Hi pat! :smile9:
What OS are you using?
What antivirus are you using?
What firewall are you using?
Are you using an SSD hard disk drive as a system partition?
Have you tried to launch sfc /scannow
(from an elevated command prompt)?
Does it show errors? (like: couldn't repair some files)
If it shows errors, run this command from an elevated command prompt (put your pc username in place of YOUR-USERNAME), post the results here, select them, click show/hide button
(when you reply to this post):
findstr /i /c:"hashes for" /c:"cannot repair" /c:"this component" %windir%\logs\cbs\cbs.log > c:\users\YOUR-USERNAME\desktop\sfcdetails.txt
