Step 1: Remove the temporary folders of Windows Update.
1. Restart the computer.
2. Keep pressing the F8 key until the Windows Startup menu appears.
3. Choose Safe Mode, and press Enter.
4. After we log on, please click Start, click Run, type in "cmd" (without quotations) and press Enter. Please run the following commands in the opened window to remove the folder.
- Type in "RD /s %windir%\softwaredistribution" (without quotations) and press Enter. Please press Y when you are prompted to remove the folder.
- Type in "RD /s %Windir%\System32\Catroot2" (without quotations) and press Enter. Please press Y when you are prompted to remove the folder.
WARNING: Please do not remove the folder "Catroot" which is a system folder.
5. Please also browse to C drive and delete the folder WUTEMP. If you cannot see the folder, please click start, run, type in "cmd" and press Enter. After the DOS command window pop-ups, please type in "RD /s C:\wutemp" and press Enter to delete the folder.
Step 2: Reset the permission of the local hard drives.
========================================
1. Click Start, click Run, type "%windir%\help" (without quotation marks) and press Enter to open the Help folder.
2. Click Start, Run, type "%windir%\system32" (without quotation marks) and press Enter to open the System32 folder.
3. Open the attachment secedit.zip, copy and paste the file secedit.exe into the folder System32; copy and paste the file secedit.htm into the folder Help.
4. Click Start, click Run, type the following command and then press ENTER.
secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose
Important: The command is complicated, therefore I suggest you copy and paste the above command into the Run box.
After running the command, you will receive a "Task is completed" message, and a warning message that something could not be done. You can safely ignore this message.
