five minutes to admin status

You’d think that a work or home computer would be reasonably secure since companies like Microsoft have 70,000 employees and perhaps some of them are dedicated to the task of keeping you safe.

Would it surprise you to know that it takes me on average about five minutes to hack into a Windows (NT/XP/7/8/10) computer?

No, really. In about two minutes and with physical access to the computer in question, I can insert a USB drive, boot it into another operating system and make a couple of adjustments. Rebooting then without the USB drive (perhaps another three minutes), the system is hacked and I have admin access.

If you wanted to protect your computer from this kind of hacking attempt, you’d need to physically lock it up when you’re not there.


Not that I use this technique, but there’s even a hack now in which something innocent-looking like a keyboard or USB thumb drive or a camera could go rogue. We’re used to devices like this to be well-behaved. If it’s a keyboard, it behaves like a keyboard. But just because they usually behave, that doesn’t mean that someone couldn’t program it otherwise.

In this case, hackers pushed code to the small firmware area of a USB drive so that it initially behaved like a USB drive… only later to change its mind and report to the operating system that it now wanted to be a keyboard. I don’t think anybody saw that coming.

So… re-formatting the USB drive would make the problem go away, right? No. In this case, the actual code is on a different chip in the device so you—the consumer—have no way to get to that chip.

But it gets worse. The device could pretend to be an Ethernet card or almost anything else. It could log your keystrokes, alter files, send emails using your email program, install software, it could transmit your keystrokes via radio waves so that someone remotely could pick them up.

If you wanted to protect your computer from this kind of hacking attempt, you’d be super vigilant about which devices you plug into your computer.


As if that weren’t enough, someone hacked what is quite possibly the most used wi-fi chipset in all mobile devices, the Broadcom chip. At least six billion smartphones are affected by this exploit which was described this summer.  If an Internet worm is created which uses this exploit, it could jump from one device to the next and right past login prompts, anti-virus software and firewalls without stopping.

If you wanted to protect your computer from this kind of hacking attempt, you’d need to immediately upgrade your smartphones and other portable devices which include wi-fi.


At the moment, there doesn’t appear to be an unhackable operating system. I can’t imagine being someone in the military or the government or in charge of a bank right now because it’s just an ugly time for security. You seemingly can’t trust even a computer mouse in a world like this.

I suppose it’s best then to suggest that you backup your important data frequently enough so that you don’t lose everything at some future date.


so many operating systems, so little time

Sometimes you need to do many things with the same hardware. Say, for example, you might need both Windows 10 and a Linux-type of operating system on the same computer. Here are some of your options for this.

You might say, “why would I want that?” There are times when you want to try out something new. You might need to test software compatibility with something you don’t have currently. You might purchase some new software or a printer which isn’t compatible with your current setup. Or, like me, you might be endlessly curious about the possibilities. You might want to create a smartphone app and need to see how that looks on a variety of phones.

Boot from a “Live” media

In this case, you have Ubuntu on a CD or on a USB thumb drive. You boot to this media and select the live option from the menu (“Try Ubuntu without installing”). You then get a Desktop experience running Ubuntu (Linux) on your existing hardware and you don’t even have to install it in the classical sense. Once you shutdown this system and remove the media, nothing whatsoever has changed on your original hard drive.


I’ve used both methods (CD and USB) and will attest that the latter will boot up faster than anything you’ve seen before, I’d guess.


  • It’s very fast to boot this way from the USB drive.
  • You can try another operating system without making any changes whatsoever to your existing computer.
  • It makes short work of hacking a Windows-based computer if you don’t know the password(s) and accessing the files on its partitions.
  • It seems to be wonderfully compatible with a variety of computers and laptops without fussing with drivers.
  • Each session takes advantage of all the available RAM.


  • Unless you change the defaults, any changes to your Desktop and configuration are lost upon restarting this session.

Set up two partitions and select one upon startup

In this case, you shrink the size of your existing hard drive’s partition to make room for another operating system.  You then install the new operating system to this second partition.

Upon restarting the computer, you then select which partition (operating system) you’d prefer.


This technique is often called “dual booting”.


  • The settings you change will be saved from one session to the next.
  • In many cases, you can access files on the other partition(s) if you know where to look.
  • You can take advantage of fast hardware like that on an Apple computer to use other operating systems like Linux.
  • Technically, you could install Windows 7 on one partition and Windows 10 on another.
  • This technique can be extended to many operating systems on many partitions.
  • Each session gets all the available RAM.


  • You have to reboot in order to get back to the other operating system to use its tools and software.
  • In the case of OS X, major version upgrades usually try to overwrite the menu at the beginning which would normally allow you to select the other partitions. It’s almost as if Apple doesn’t want you to do this and breaks things on purpose, of course. If you’re technically-minded, you can fix this each time however.

Set up a virtual manager (VM) and “spin up” an operating system

This seems to be the preferred and newest method these days. You run a virtual machine manager, create a virtual computer using this technique and then install the new operating system to this.


You then boot up the virtual computer and you see this as a window on your Desktop.



  • You can copy/paste from a Windows application into a Linux session’s Terminal session or any similar combination of from/to.
  • For demonstrations, you can easily show that something works with multiple operating systems (without rebooting or bringing multiple laptops).
  • Depending upon how much hard drive space, RAM and processor speed you have, you could potentially run several virtual machines at once.


  • Technically, it’s the most challenging of the various options and the learning curve is steep.
  • It may require more RAM memory than what you currently have for this to run well.

Progress so far

I have plenty of experience using the first two methods above (live- and dual-boot) but have recently been working with the VM option, as described below.

Dual-boot MacBook

I’ve setup my MacBook Pro to boot both OS X and Ubuntu. It seems to work great so far. I hope to next setup a VM so that I can emulate a Raspberry Pi computer within the MacBook itself (for development purposes).

HP Laptop

I’ve setup my HP laptop to boot Ubuntu and have added a VM which has Windows 10 loaded in it. Remarkably, the Windows 10 install actually works better than the original (native) installation on this laptop.

Multi-boot Raspberry Pi computers (IoT re-purposing)

Since the Raspberry Pi (3 and Zero) computers have an easily-replaceable microSD card in them, I now have a small library of different images with which I may boot any individual computer. It’s just important to label each to avoid confusion.

So I might pull the microSD card for the robotic tank project out of a Raspberry Pi, replace it with the card for the closed ecosystem or for a different project altogether. Once it boots, it’s now a completely different computer, if you will.


Multi-boot 3D printer

Technically, the Robo C2 printer has a Raspberry Pi computer inside so it makes it easy to boot to different versions of the software. This is useful when you’re modifying things to add on new features, for example.

Smartphone software on a workstation

I’ve also had the opportunity of installing Android on a standard Dell Vostro 200 desktop computer. (It’s good for testing software and websites.)

Cloud-based alternatives

There are entire services available at Microsoft, Amazon and presumably Google in which you “spin up” a virtual computer and remote into it.

Amazon’s offering is called EC2 and I’ve had the opportunity to use it in the past. In the span of two hours, I was able to spin up or “instantiate” a virtual SQL Server in a datacenter somewhere, to upload a corrupt database, fix it there and then to download it back to me. I then killed that virtual server. The total cost was something like $4 to “borrow” their virtual hardware for a couple of hours. Compare this to the cost of purchasing an actual server, paying for Microsoft licensing, waiting for everything to arrive, setting it up, etc. I literally saved thousands of dollars with a service like this.

Microsoft’s offering is called Azure. I can’t say that I’ve used it yet but it works essentially in the same way that EC2 does: define an instance, spin it up and remote into it.

Looks like Google’s offering is their Compute Engine. It sounds like they’re trying to play “catch up” to both Amazon/Microsoft on this one.

There’s another player in this space, appears to be offering remote sessions into what are likely discreet/physical Apple computers. For all practical purposes, it would likely behave like a virtual computer might.

Private cloud

And finally, I had the opportunity to re-purpose about eight Dell Vostro 200 computers from work into a MaaS (metal as a service) private cloud. The underlying layer of software which did the cloud part is called OpenStack which allows you—like Amazon itself perhaps—to be the host for spinning up virtual servers.

It takes a lot of work to get the initial one or two computers running for this. But then, using a concept called Juju charms, you select what are essentially recipes of things to install which have complicated inter-dependencies and it seems to make it all work for you. Seeing these things run is pretty impressive given that this is in the free, open-space world.

The future

It’s hard to guess what’s next in this series of events. We may soon be running a VM with Windows 10 on a wearable single-board computer like the Raspberry Pi 3 or similar. In theory, then, you might wear a pair of Google Glass(es) or the Microsoft HoloLens which would interface with the Pi computer via Bluetooth. Given the lack of a keyboard, presumably the interface might be like the Amazon Echo/Alexa service: you ask for something, the system must recognize the command, submit it to a server and display the results or iterate through them via voice.

And yet, given the augmented reality (AR) side of things, you might say “keyboard” and a virtual reality keyboard could appear on the physical horizontal space in front of you and you just “type” on an imaginary keyboard to input data.

The interfaces could evolve to project these virtual keyboard-type interfaces onto an imaginary glass wall in front of you, much the same as you see in sci-fi movies these days. These glass-like devices probably would incorporate an outward-facing camera to catch and interpret your hand movements into discreet commands like typing, page-forward, scroll-down, dismiss window, etc.


taking the bite out of offers an online service in which you can digitally apply postage to an envelope.  They even include a nifty/free digital scale to attach to your computer.


The problem of course is that in order to make back the cost of that “free” device, wants to charge you on a monthly basis to use this service and most people decide that it’s not worth those charges.  I often see these sitting idly on someone’s desk and it’s only useful for measuring the weight of something.  Without their service, you’d then need to manually lookup the postage and then count the right number and types of stamps.

I’ve written a Windows program which will do all that for you, weighing the envelope, calculating the postage and letting you know how many stamps of which kind to put on it.


Here is the new repository on  You can run it directly or build the program yourself if you have a copy of  Visual Studio, to include the free Community version.  Your computer will need the .NET Framework 4.5.2, for what it’s worth.

the rise and fall of the microsoft empire


Our historical timeline begins in 1975 when an unlikely duo—Paul Allen as Batman and Bill Gates as his awkward “Boy Wonder”—started Microsoft Corporation.  I’m guessing that ro-sham-bo was involved in this decision but incredibly somehow Bill was made the CEO when the company got its start.  Maybe dropping out of Harvard gives you that kind of confidence.



Nothing really significant happened until they managed to modify an existing operating system for the IBM PC in 1981 from another company and rename this to MS-DOS. Significant sales of the IBM series of computers and those of their competitors then launched a thirty-year stretch of dominance in the business world in the area of operating systems, software and development platforms.

For most of us, we reasonably dismissed Apple’s hardware and the MacIntosh operating systems as nothing we could seriously use in business outside of the marketing department.

Consumers bought new versions of software and that license was good for life.  It could often be transferred from one computer to the next as long as the last one was de-registered first.  If you built software for Windows, you likely used a Microsoft compiler to do so and you paid for that.  In fact, the Microsoft Technet collection of CDs was quite expensive.


About six years into the “Internet Tidal Wave” as Bill would call it, Microsoft was starting to lose its way.  They tried to dominate in the browser wars but never quite managed to quash the competition.  Others saw their efforts in this area as annoying.  Their software for creating programs, Visual Studio, first hit the scene about four years prior to this.

Google was founded some five years prior and was just beginning to get attention from an investor before they had anything real yet.  In 1999 they moved from their garage to an actual building in Palo Alto.  Yahoo’s popularity as a search engine from a decade ago was waning.  Google’s ad-based revenue from keywords was paying off; they’d planted a money tree which eventually created an entire forest of money trees for them.  It wouldn’t be long until Microsoft’s executives behind closed doors would consider Google their biggest threat.

About this time Apple created a very clever method of provisioning content for one-and-only-one device within the music-delivery space.  The iTunes store would turn out to be the goose that laid the golden egg, as seen in the following revenues.  And yet, it would take years for either Microsoft or Google to realize the beauty in this fulfillment model and to come up with their own versions.


The “Internet of Things” concept started gaining in popularity at this time.


Microsoft’s attempts at copying Google’s success (MSN Search, Windows Live Search, Live Search) now culminated in the introduction of Bing as their default search engine destination for all things Microsoft.

Apple introduced the first iPhone and the first iPad about this time, noting that the same provisioning model from iTunes was incorporated into both via iOS.  The subscription model of sofware licensing was born with this, if you think about it.  If you wanted to write a program for either, you needed to use Apple’s software to do so.

Google has just introduced Chrome as a browser and would begin their campaign to slowly break Internet Explorer.  The same was true of the Android phone and its related operating system.  It would take a few years for Microsoft to catch up to either the iPhone or the Android before releasing their own app-savvy smartphone offering.

Amazon some three years prior had introduced the beginning of what would be a full complement of cloud-based services to support web development.  It would take Microsoft two full years to realize that they needed to be in this space and they didn’t have their offering ready for a few years more, too late to effectively compete. had just celebrated their first year online, hosting over 46,000 repositories by then.  The world of open source was the very antonym to the way that software had been developed prior to this.

The free Ubuntu operating system was released about four years prior to this, backed by the well-funded company Canonical.


Microsoft releases Windows 10, “the last version of Windows” (they claimed).  Rumors suggested that Windows would eventually go from a version-based license model to an annual-subscription model with respect to pricing.  I think it’s safe to say that the market hasn’t really embraced either Windows 8 or Windows 10.

The subscription-based model for Office 365 was introduced four years prior to this so the writing was definitely on the wall:  Microsoft wanted to depart from their former methods of making money and to chase the monthly subscription model.


The world of open source was offering new programmers a wealth of free code.  All they had to do was to take it and make it their own.  Formerly, Microsoft-friendly coding languages like C, C++, C#, VB and .NET dominated the playing field but this graphic shows how the game had changed.


And here we are, present-day.  That curious number 42 now describes the number of years that Microsoft has been around.

Yesterday evening, I attended a very geeky meetup of perhaps fifty or sixty coders and only saw one Windows-based laptop.  Almost everyone had a MacBook of some kind.

I just spent about two hours today installing the free Visual Studio Community 2017 software so that I could—in theory, anyway—alter a free copy of the source code for TightVNC software.  Out of the box, so-to-speak, Visual Studio doesn’t want me to build this project since it uses an earlier target platform (Windows 7 or 8, one would assume).

Microsoft only wants me to make things for Windows 10.

So rather than making it easy for me to build a program that will happily work with Windows 7, they’re forcing me to jump through hoops in order to add the necessary pieces for this to happen.

Add two more hours to this and I find that my installation does not want to download the earlier pieces to allow this to happen.  I’m forced to then upgrade the code to Windows 10 compatibility mode… only to find that the build fails with 528 errors.

The main crux of all these errors appear to be:  “we can’t find common files”.  It’s a very amateur sort of error from a company that’s been providing compilers for several decades now.

I have to think that Microsoft doesn’t want me to do anything with Visual Studio unless it benefits Microsoft.  And this is the core of the reason why I suggest that they’re doomed.

Every time a coder like myself runs into obstacles like these, the usual seed that’s planted inside their head is “this would be easier with another free compiler or another language from someone else”.


Fast-forward another five years and Microsoft will have lost ground on many fronts.  New software development here, there and everywhere will be via some language which wasn’t popularized by Microsoft on computers which aren’t Windows and with browsers which aren’t Internet Explorer or Edge.  Our toasters and refrigerators and our cars will be powered by the Ubuntu operating system or perhaps Debian, a similar free Linux flavor.  These appliances will be connected to our wi-fi and even to the Internet but there won’t be a scrap of anything Microsoft about them.  They’ll be coded up with something that isn’t C#, doesn’t use .NET and doesn’t need Visual Studio in order to compile it.

The only thing with a Microsoft pedigree with some staying power could be some of the websites and services currently served up at Microsoft’s datacenters via Azure.  But Amazon or Google could kill that by simply lowering their own prices for cloud-based services.

iphone without itunes

You know how Apple can be sometimes; they feel the need to control everything. So for a Windows-based computer, they want to force you to install the entire iTunes collection of software just so that you can get to your files on your iPhone. As an I.T. person, to me that’s just way too much software to be adding to someone’s computer setup.

Why not?

You might just ask “why not?”  Why not just install iTunes? One of the subtle changes that iTunes makes in terraforming your Microsoft computer for its own needs is to install a variety of software to make things more Apple-friendly.

For example, in an Apple-based network the Bonjour service allows lookups for printers normally but allows for almost any device to broadcast its existence on your network. The downside to adding a different printer lookup service is that you might have a number of printers already which broadcast via Bonjour and can now be seen by your computer this way.  And yet, you might not have a working Microsoft driver installed to make all this happy. The printer when added simply doesn’t work and yet it seems to work for everyone else on the network who didn’t install iTunes. Rule of thumb for success: don’t arbitrarily add services and things unless you exactly know the ramifications for doing so.

Rule of thumb for success: don’t arbitrarily add services and things unless you exactly know the ramifications for doing so.

The problem

If you simply plug in your iPhone into a Windows 7—based workstation you’ll see it download and install a default driver. Unfortunately, the Internal Storage section of this device won’t show anything in it.


The fix

Unbelievably, the fix is much easier than I’d imagined. Immediately upon tethering the iPhone the very first time to the Windows computer the iPhone will buzz twice (telling you not that it’s now charging but it’s trying to tell you that it’s displaying a notification).  The message is crucial to your success but Apple in its infinite wisdom doesn’t decide to wake the phone up for you.  You need to manually wake it up first to see it:


Select the Allow option here and suddenly Explorer will now present you with a DCIM folder, below this a 100APPLE folder which contains your images.


Why is this considered a smartphone?

That’s a good question to ask. Why would Apple decide to block access to the phone on a Windows computer by burying its head in the sand when an important access message is being hidden behind a sleep state? I suppose they could suggest that if the phone is sleeping then the rightful owner may not be in control of it and that nobody should have access as a result.

But why not simply bubble that information up to Explorer with a dialog box so that the user will know the status? It just silently doesn’t see anything at all for the device.

If you read the many support threads on the Apple site nobody ever mentions such an easy solution. The reason of course is that Apple wants you to install all of their software on your Windows-based computer, too. The biggest reason is that the iTunes application is a shopping cart and you’re a consumer to them.
