I do NOT have AVAST. I do have Malwarebytes and Microsoft Security Essentials.
A CBSPERSIST was created as of 5/24. CBS.LOG is ACCESS DENIED and is, I am sure, since the 5/24 date. I have run TWEAKING.COM free edition this morning and saw no problems. How would I get a copy of the CBS.LOG with Access Denied?
After that is figured out, I could run KB4474419 direct again.
When is CBSPERSIST created from CBS.LOG?
