Run Windows 8.1 For 90 Days Free
 

I wonder if a 90 day test drive would change some people's opinion of Windows 8.1? For Windows 8 users, the decision to upgrade to 8.1 is virtually a no brainer. But those of you running previous versions of Windows would have to shell out $120 for Windows 8.1 or $200 for Windows 8.1 Pro. Instead, you can install the Enterprise evaluation edition first to see if 8.1 is worth your hard-earned money.
