Hello, I just installed windows 7, and have a few important questions. 1 - When a clean install is done, going from XP to 7 is there the folder windows.old created, or is that only done when it is an upgrade? 2 - Every day, a few times every day I am having programs freeze on me. I have to reboot to "safe". I check the events viewer and it says that the program hang. So it basically tells me nothing! 3 - I also have been having the BSOD, sometimes with the nstor. Is that the Nvidia? 4 - When installing some of my proggies I have had permission denied on a few of the .dll/s. I just wanted to make sure that it was ok to add the Admin to those dll/s. I didn't change the system permissions just added the Admin. I was possibly planning on reinstalling win7 if these errors and freezes continue, unless someone has a suggestion or a tweak to possibly make them stop. Thank you so much!
