Windows 10: How do you replace a possible corrupt System Registry

My question is does Windows 10 update ever clean the System Registry? Or is all of your old data left there forever?


I believe my Desktop's, System Registry is corrupt with old data that is no longer used on my PC. I wouldn't doubt that there is data there from way back to my Windows 7 installation.


So, I want to clean my entire System Registry.


" Does a clean install also clean the system registry ? "

Please a yes or no will do!

Edge corrupted possibly by a trojan, settings menu does not work properly

Hi Dan,

To resolve the issue, we suggest that you check for corrupted Windows system files. System File Checker (SFC) is a utility in Windows that scans for corrupted Windows system files. If it finds a problem, it will try to replace the problematic system files
from a cached version that’s on your PC. If SFC can’t replace the files, the Deployment Image Service and Management Tool (DISM) can check the corrupted files then download and replace the files through Windows Update.

To run System File Checker (SFC), follow these steps:

• In the search box on the taskbar, type command prompt, press and hold (or right-click)
  Command Prompt, then select Run as administrator >
  Yes.
• At the command prompt, type sfc /scannow (note the space between sfc and the /). Scanning will take a few minutes.
• Do one of the following, depending on the results of the scan:
  • If SFC finds corrupted files and replaces them, restart your PC and check if the issue persists.
  • If SFC doesn’t find corrupted files or finds corrupted files but can’t replace them, try using the Deployment Image Service and Management Tool (DISM).

To use the Deployment Image Service and Management Tool (DISM), follow these steps:

• In the search box on the taskbar, type command prompt, press and hold (or right-click)
  Command Prompt, and then select Run as administrator >
  Yes.
• At the command prompt, type dism.exe /Online /Cleanup-image /Restorehealth (note the space between dism.exe and / and each switch (/)).
• If DISM finds corrupted files and replaces them, restart your PC and check if the issue persists.

Note: You need to be connected to the Internet to use DISM, and it might take several minutes to finish.
