Ok first thing is first, I'm not very good with computers, so if you go step-by-step it'll be great. I got a laptop not too long ago, and it came with Vista Home Premium. I disliked Vista after awhile, having problems with it, and Windows 7 seemed like a good idea. I installed Windows 7 today, and everything was fine. Except, I have Windows 7 Enterprise Edition, not Home Premium, so I wasn't able to just click "Upgrade", and chose the other option, the custom install option. I installed everything and it said all my old folders and what not were in Windows.old . My computer came with a 250gb Harddrive, and it was down to 90gb (About), and it was like that when I went into My Computer. The problem is, I can't really access/uninstall my old programs to install new ones onto Windows 7, and really need the space. What do I do? I'm sure this has been answered before, but I just need to get this fixed, sorry.
