I use Windows 7 Home Premium 64-bit on my computer. Previously there was no problem. I have a new computer that I bought less than a year ago. I used it as usual, but when I opened it again the next day, I couldn't login to Windows, I wasn't recognized as an administrator, the password failed and access was denied.
Then I tried to get in through safe mode, deleted the password, opened Regedit, and I saw that there was a .bak file in the profile. After searching the internet, I tried to create a new profile and remove the duplicate file, but I still couldn't login. Then I returned it back to its original position from safe mode again. I could login to my computer in safe mode. I didn't find all the data I had stored on the computer. Then I opened the local disk [ C ] -> users -> homepremium where I found all my files without any loss. But in the users folder, I saw my profile had duplicated up to 7 profiles >> user.temp.001 - 007.
I used my computer as usual while backing up my data. The Windows Update updated automatically (I didn't change any settings), The next day I couldn't login anymore. It said the group policy client service failed the logon. Access denied. I tried to get in through safe mode as before, but I couldn't, just login and then log out, and repeat. I tried to get in through safe mode from the command prompt to open System Restore, but I also couldn't, just login and then log out.
What should I do? I haven't finished backing up all the data that is stored in my computer because my external hard drive was damaged (I backed up the data to a DVD). I can't lose my data again (with my external hard drive broken) because I have important files. Please help.
