|According to a Microsoft posting on PCWorld, end of support for XP will only affect security updates and phone/technical support. It will not affect the ability to activate XP.|
I don't want to open a can of worms here, but...
There is still a huge user base on Windows XP, including me. Many old machines just can't run Windows 7, they max out at 512MB RAM, drivers were never made, or programs (especially MS DOS ones that are prohibitively expensive to recompile) are incompatible. This last one is a big deal in many corporations.
...so in the end I expect Microsoft's hand will be forced to extend XP support at least one more year, a last minute reprieve until April 2015.
If I'm wrong, we've got 9 months to go until the viruses start spreading and taking over the internet.
Sasser, Blaster, anyone?
