The win7 system account accidentally deleted how to do

win7 system account accidentally deleted, there will be restrictions when managing the computer disk, how to solve such a problem? Let's take a look at the methods below.

How to solve the operation of a disk operation "You need administrator privileges to perform XX operations"?

The reason for this history of blood and tear is that I want to solve the encryption disk. Unable to install the problem in the E drive.

Each time you paste a file into the E drive or remove the file from the E drive, you will see no administrator rights. For this reason, the encrypted disk cannot be installed on the E disk.

It is puzzling that from the control panel - account management you can see that the chenjun account is already an administrator.

After the online search, the reason for this phenomenon is that some security processing is automatically performed when the system is installed. To solve this problem, simply right-click on the E drive, select Properties - Security, and add a series of permissions to the account or group.

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. So the brain cramps, it feels that it is an account problem, then delete the chenjun account and change the Adiministrator account name to chenjun.

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

How do I enter the win7 system without an account password?

The original account has been stopped. Use, but other accounts can't get in. When preparing to reinstall the system, the following methods were found from the Internet:

Step 1: Restart the computer, press F8 when booting, and then a mode selection interface appears. Choose a secure interface with a command line. Then the system will jump to a dos interface.

Step 2: Enter the following command at the command line to create a new account and add administrator privileges:

1NET USER abcd /ADD NET LOCALGROUP administrator abcd /ADD

3 Step: Restart the computer and select the abcd account to enter the system.

[If you simply forget the password, you can proceed to step 4]

Step 4: Computer-Management-Local Users and Groups, double-click the original account to select the password.

Delete account abcd.

How to solve the problem of recovering deleted accounts when the system is equipped with anti-virus software?

Because only deleting the original account and not deleting the account file, 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 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.

Thinking of using a safe mode when no accounts are entered into the system, it is vaguely felt that a safe mode can be reused. 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.

Summary

Control Layout - The account displayed in Account Management and Computer Management is slightly different, mainly based on the control panel.

After accidentally deleting the account, you can actually restore the account in direct security mode, no need to create a new account to enter the system.

The method of entering the system without account and password will bring security risks to the company. From the perspective of security, the company should cancel the security mode of the office computer from the technical level or set permissions for it.
