For most home PC users, upgrading to the latest version of Windows is pretty straightforward and easy, assuming you can afford to! But for companies that have a large number of Windows workstations in use, upgrading your computers can be a huge (and expensive) process and therefore doesn’t happen as often as with home users.
Many companies are just now moving off of Windows XP after many years of satisfaction with the 12 year old operating system. In fact, Windows XP will not be supported after April 8, 2014. Most companies were wise enough to stay away from Windows Vista when it came out but are now realizing its time to upgrade. Microsoft is having trouble getting home users to switch to Windows 8 and it seems the same thing is happening with corporate users.
Forrester Research released a report saying that Windows 7 is used in around 50% of all enterprise installations even though Windows 8 has been out for some time now and has a business or enterprise version of the OS. This is especially true for companies that are finally upgrading from Windows XP. Of the 273 IT professionals who are going to be upgrading from Windows XP, only 2% said they were going with Windows 8 compared to 69% who said that they were going with Windows 7 instead.
The main reasons that corporations are going with Windows 7 over Windows 8 is that Windows 7 is closer to XP and will take less getting used to an require less training on. Also, Windows 7 has been around since 2009 and has proven itself to be a stable operating system. And for companies who do in house development, Windows 7 works better when it comes to compatibility.
