Windows 10: Running sfc /scannow more than once

I've run across the suggestion that when running sfc /scannow it should be run two or three times, even if you received the message Windows Resource Protection did not find any integrity violations. My understanding has been that if no integrity violation are found you shouldn't need to run further scans. True of false?

Run CCleaner and sfc /scannow?

Hi,

How often should I run CCleaner and sfc /scannow?

Thanks

 

sfc /scannow won't complete

Hi,

As per the information, I suggest that you run SFC in Safe Mode with admin privileges and check if the same issue occurs.

If the issue persist, you can check for the following:

1. Scan the Hard Drive for Errors

The first thing to do is to tell Windows you want to perform a file system check on the hard drive to ensure there are no errors. If there are errors on the drive, 'sfc /scannow' may fail.

To scan the drive for errors, do the following:

• Open an administrative command prompt. In Windows XP, click Start -> Run, and type in "cmd.exe" and press Enter. Click Start and type in "cmd" (no quotes). Wait for Command Prompt or CMD.EXE to appear in the list of options and right click it, then select
  "Run as Administrator".
• A black command prompt window will appear on the screen. Highlight the following text with your mouse: "chkdsk /x /f /r" (do not include the quotes), then right click over the highlighted text and select Copy. Next, go to the command prompt and right click
  in the middle of the window and select Paste from the dialogue menu. The command you copied should have output to the command prompt. If it did not, repeat this step until it does. After the command is output, press Enter on your keyboard to execute it. When
  prompted, press "Y" to have chkdsk scan your hard drive for errors on the next reboot.

2. Enable the Hidden Administrator Account

Next we'll enable the hidden administrator account so that you can perform the 'sfc /scannow' command in a clean environment.

To do so:

• Highlight the following text with your mouse: "net user administrator /active:yes" (do not include the quotes), then right click over the highlighted text and select Copy. Next, go to the command prompt and right click in the middle of the window and select
  Paste from the dialogue menu. The command you copied should have output to the command prompt. If it did not, repeat this step until it does. After the command is output, press Enter on your keyboard to execute it.
• Please note that you will most likely want to disable the administrator account after you have finished making changes listed in this document, otherwise anyone will be able to login to your computer as the administrator user without using a password and
  make changes to the system without any authorization. You can disable the administrator account using the exact steps you just took above, except you would replace "net user administrator /active:yes" with "net user administrator /active:no".

Hope this helps

Regards
