Thanks for responding. Now, I'm not saying a System Restore wouldn't help if the issue happens again, but, my question is if (which I should had said in the OP but forgot...) I have Steam in my D drive, which I bought Skyrim years ago is on there. Should I tell System Restore to protect the D drive by "Only restore previous versions of files", or is it pointless to, and only the C drive will work? Again, I just want some sort of insurance (if it was registry corruption, that is) that the problem can be reverted and I won't need to reinstall Windows again. I know how to do a hard save in Skyrim. But that too, I'm hearing even with this, may or may not remove all traces of the mod(s) if I fall back to it. This isn't as simple as just doing this if it starts to happen again. If it's the registry, I need an "advanced" backup. I have no proof it was a mod that caused the issue in the first place. The only thing I know, it's something I did. But to know what that something was, I need help from my computer to save it. Only then, will I 100% know the exact cause and how to prevent it. I know I'm working myself over this. But I just got the damn thing fixed. I have to make sure it doesn't happen again, so I can freely play with no worries.
