How to solve when a disk operation display & ldquo; You need administrator privileges to operate XX & rdquo ;?

The reason for this history of blood and tears is that the author wants to solve the problem that the encrypted disk cannot be installed in the E disk.

But at the time, I didn't find a way to follow this idea, but I suspected that there was a problem with the administrator status of my account. So I checked the account from the computer-management and found that in addition to the chenjun account, there is also an Adiministrator.

The next tragedy happened. There is no account available to log in to the system ……

How to solve the problem of restoring a deleted account when the system is equipped with anti-virus software?

Since the original account is deleted and the account file is not deleted, the guess account can be recovered. Sure enough, Start - Attachment - System Tools - System Restore, found that there is a restore point in the morning, this restore point has all the data I need. Then the restore point is selected for restoration.

However, when the system automatically restarts, a reminder window appears, “Open anti-virus software, system restore failed”. Turn off the anti-virus software and try again.

After the inspection, it was found that although the anti-virus software was not turned on, there was an anti-virus process. Trying to end the process, but the window prompts "Cannot end the system process". I tried several kill process methods online, and they were all invalid.

I thought that when I entered the system without a account, I used the security mode, and I felt that I could use the security mode again. Then restart the computer, enter the safe mode, click Start - Accessories - System Tools - System Restore, select the restore point in the morning.

Finally, the account was successfully restored, ending the history of blood and tears.
