The Windows 7 beta version is a very good version of Windows. If you haven’t heard, Windows 7 is the next version of Windows coming out. Microsoft that this version will better the Vista debacle. Although Vista is pretty stable right now, it has had trouble regaining the confidence of computer users. So, Microsoft is trying to push out the latest release of Windows 7 as fast as possible.
The beta version of Windows 7 was available for release months ago. It is no longer available on the Microsoft site. For 
those lucky ones who use the Windows 7 beta version, apparently Microsoft released that there is not an easy way to upgrade from the Windows beta 7 version to Windows 7 full version. There are several complicated steps to follow to perform the upgrade. Further, Microsoft recommends to avoid performing the upgrade from the beta version if possible and just use Vista for now.
We haven’t performed the upgrade as of yet since the full Windows 7 version is not available, but if Microsoft says it will be a troublesome upgrade, we’ll take their word for it. Try to skip this computer upgrade and just install a clean Windows install of version 7 when it comes out. Avoid this tech issue if you can.
