Witch Windows OS is best?

Windows 7 is best

Support for Windows XP SP3 ends on April 8, 2014

Well Windows 8 in my opinion is great in that its modern, sleek and intuitive, and its much easier than reported to use. Windows 7 is the best out the two for compatibility as Windows 7 has an XP mode, which essentially runs programs designed for XP and below on Windows 7, and they may not work on Windows 8 if you have an old/designed for XP/Lower OS without XP mode on Windows 7, however if you have no software that's essential, or is made for example, Windows 2000, then Windows 8 is your best bet, but 7 is best for compatibility. Also Windows 8 has apps that are made specifically for it.

All in all, I'd say go with Windows 8 as its easy use (might take a while such as a day or two to get custom to it), but Windows 7s best for compatibility, but if you have no old software to run on it, then 8s your best bet.

Also XP Support runs out in April 2014

You could Install Android 4.4.4 on your computer, it was released yesterday

What's going to happen with your computer next year when M$ stops supporting W7, It's all ready 4 years old now, MS are NOT going to support W7 like they did with Xp.

You can Download and try out the latest January 29th 2014 Free Linux Operating system from Zorin. I am running it on a 14 year old Dell 1100 laptop that has no hard drive installed in it and 512 megabytes of Ram,

I boot it up from a usb Flash/jump drive. It's fast, I can get on the web using a wireless usb Linux can do things Windows 7 or 8 can't do. I recommend you

Check out Zorin here it costs you nothing to look, and you will learn a few things, here is their website go do the tour of the free Operating System,

I like Windows 7 and Windows 8.

Support for XP will end this April, using it after that time will be an increasing security risk. Windows 8 64 Bit (not 8.1) is probably the most stable providing its clean installed with correct drivers and a Legal copy. Windows 7 64 is also good not quite as quick as Windows 8, but the advantage is its more compatible with known software.

windows 7 is a better platform .. windows 8 is buggy and crap .. buy win 7 retail if you can

i would recommend Windows 7 as is use it personally.
