Wasn't support for the XP going to end soon anyway? If that's the case an upgrade would be the only option. But again Microsoft's brainless pricing of a dumbed down OS is hurting everyone.
The official end of support for almost all versions of XP is 08/04/2014.
It is? I had no idea. But yeah, I've always found XP to be very reliable, so I never bothered upgrading.
Most likely, after the end of support I will switch over to an offline environment for my workstation and use a linux distro for online web surfing.
(At least until until I get a look at Windows 9, or possibly I'll look into MAC OSX ~whatever version.)
I've more than enough games (not played or completed) to last past then; I have the CD version of Arx Fatalis (from when it released), and haven't ever completed it yet.

*(Though I use the GoG version and Arx Libertatis)
