Whether or not Windows 7 does launch in October as previously suggested, those who have (or plan to get) Release Candidate will be happy to hear that Microsoft won't be pulling the plug until June 1, 2010, well over a year from now and 11 months after its initial expiration date. After that, you're gonna have to fork over the Benjamins for one of the retail SKUs if you wanna keep 7 alive. As for those still living in Redmond's past, the company's also extended the life of XP, at least for OEMs. Companies using the older OS will still be able to install it on netbooks for up to one year after 7's official shape date. Seeing as the new system's likely to have a more expensive licensing fee, it's probably the best move if the company plans on keeping that 96% grip on the netbook OS market.
