Step3) Check if Windows image is corrupted or not.
Execute the following commands in Windows Power Shell with admin privilege. 

C:\WINDOWS\system32>chcp 437
C:\WINDOWS\system32>DISM.exe /Online /Cleanup-image /ScanHealth

Step4) If the Windows image is fine, need to make Windows Registry clean.
Use Windows registry cleaner like CCleaner to clean up registry.
Note : Palo Alto Networks doesn't have recommended applications to accomplish this task, any applications are fine.

Step5) If the customer cannot accept the risk to use Windows registry cleaner, re-installing Operating System itself can fix the issue.
