I originally upgraded from Vista to the release version of Windows 7. I've seen posts saying that it was much smarter to backup your stuff and do a clean install. Would it be wise to instead, back it all up now and just do a fresh install?
Only if you are having problems! Maybe you got lucky and things worked the way they should have in theory. I would do some searching on partitioning. I put my OS and programs on one partition and the data on a second. That way if you reinstall your OS is doesn't wipe your data, but you want it backed up in case. Windows Disk Management will handel the partitioning.
