I don't know how to fix this problem.
I followed Step 1 of https://support.microsoft.com/en-us/kb/957310 but this is what happened:
Microsoft Windows [Version 10.0.10240]
(c) 2015 Microsoft Corporation. All rights reserved.
Beginning system scan. This process will take some time.
Beginning verification phase of system scan.
Verification 33% complete.
Windows Resource Protection could not perform the requested operation.
Can someone help me please?
