Use the System File Checker tool to repair missing or corrupted system files.
To do this, follow these steps:
Open an elevated command prompt. next to Windows start button, perform a search for cmd.exe and press enter key.
The top search result should be Command Prompt.
Right click on the “Command Prompt” result and then Left click on the drop down list to select “Run as Administrator.” When asked for further run permission, click YES. The black command window should then open with administrative privileges. This is known as an elevated command prompt.
If you are running Windows 10, Windows 8.1 or Windows 8, you should first run the inbox Deployment Image Servicing and Management (DISM) tool prior to running the System File Checker.
Type the following command code in the black elevated command prompt, and then press Enter.
DISM.exe /Online /Cleanup-image /Restorehealth
It may take several minutes for the command operation to be completed.
Now, after DISM has been run, in the same elevated black Command Prompt window, next run the system file checker (sfc.exe) to scan for and repair corrupted or missing system files, as follows.
►CMD Command
sfc /scannow
Check to see if this corrected the problem. If not, then move on to the next possible fix.
