Hello!

If you haven't already submitted a support case and is still getting this error, here are some things you can try. You need to run these tools and see if any of them report errors that can't be fixed.

To fix this problem, you have to try the following:

  1. You have to check Disk Error first.
  2. You have to check the system file checker.
  3. You have to check the system update readiness tool

If the above solutions come up as clean, you have to scan your system with another anti-virus or anti-malware software. It is highly recommended to use Microsoft security essential from Microsoft Corporation.
