What enterprise customers prize over everything is stability, and Windows 7 has time, familiarity, extensive testing and total peripheral compatibility on its side.
Those upgrading from Windows 8 to 8.1 have also run into problems, with users complaining the update broke simple things such as the ability to print.
Gone are the days when you have to distract yourself by going to make a cup of tea while your system wakes up. Microsoft engineers combined the hibernation and shutdown modes into one for Windows 8, and Windows 8.1 uses a hybrid boot mode that allows the PC to start up much more quickly.
The kernel lets it hibernate instead of shutting down completely, and the use of cores makes it possible to start-up in seconds.
Microsoft used Windows 8 as a guise under which to revamp the engine, and the results is a much faster system that consumes fewer resources than before.
This makes it a better choice than Windows 7 for low-end PCs.
Until Microsoft stops support for Windows 7, people will continue to choose it over the alternative. Following XP’s demise, the upgrade candidates were Windows 7 and Windows 8.1, and we have broken down the key features to help you decide which is the better choice (fast forward to our verdict).
Windows 8 machines only take 10-15 seconds to boot up, with some switching on even faster depending on the SSD.

This doesn’t, however, come with the return of the Start menu (thankfully confirmed for Windows 9 in 2015), instead simply switching users between screens.
To say the revised interface has had a polarising effect is an understatement, and there is no shortage of people who have complained about Metro since it was released.
