If you're still using Windows XP, you just won $100 from Microsoft.
The only catch is that you have to upgrade to a new Windows 8 computer.
Those who are eligible for the promotion can redeem the credit at Microsoft's online store or their retail shops -- and the fact that you still use the 13-year old Windows XP is subject to verification by Microsoft (. The offer is good for PCs ranging in price from $599 and $2,299 and will run until June 15. )
The promotion is part of Microsoft's plan to get the last remaining Windows XP users off the operating system before the April 8 end of life date. After April 8, Microsoft will no longer issue security updates to address viruses and exploits to the operating system.
The latest figures from NetMarketShare still show Windows XP pulling 30% of Windows users, though the vast majority of those are thought to be PCs from China and the enterprise space.
