Hi, I've had Windows Vista for a little over a year and I have been completely discontent with it. It's gotten so bad to the point that now everytime I start up, I get a bunch of random corrupt file messages, drivers that need to be reinstalled, etc. Also, over the course of time, a bunch of my folders and programs just become randomly corrupt and I have to reinstall them. I am very happy that Windows 7 will be coming out in a couple of weeks. I was just wondering, will merely upgrading from Vista to Win7 while keeping all my files and programs intact fix my issues? Or should I play it safe by backing everything up and performing a custom install and wipe everything out and start fresh? Would doing this make a difference? Also, if you guys do advise me to perform a custom install, I would want to get the Professional version since I currently have Home Premium right now. My other question is would installing Professional weigh down my computer more than Home Premium would? Would my computer be slightly slower because of the more powerful version of this OS? Thank you very much for your help.
