Yeah, so I upgraded from vista to 7 but the upgrade was working very slow, so I went to do a complete fresh install. And, well, I wanted to keep the registries for some of my installed games because I either lost the install disc or the downloaded installer, and I copied them to another hard drive. Now after the reinstall, I added all the backed up registeries from my previous install(I know, incredibly dumb) to my new install, and well, I put my backed up games back in old folders, and they worked smoothly. But, for some reason, randomly after each night, all my history gets erased. I mean all, like all the browsers, I have IE, FF, and GC, and my windows history, like the recent items, get erased.
