Windows 10

I managed to mess my drive up to the point that Windows wouldn't boot. Trying to keep all of my data, I copied the folders in C: to another drive, reinstalled Windows and copied them back. Now, when I try to log into my account, with the same name I had before, I get an error saying an error occured with the password. Trying to change the password is no good as my nework adapter is not working, because Windows, unlike Linux, can't seem to ship with the necessary drivers. In order to install drivers, I need to log in and now you see the problem. I tried adding a new user through CMD in the recovery, but I can't seem to choose that user when trying to log in. I also cannot see the user with the corrupted password when i run "net user", but I do get a return listing some of the default accounts, along with a line saying the command couldn't complete. Now I'm running low on ideas, so any help would be greatly appreciated.
