I've run the Windows Update Diagnostic tool. I've followed the instructions from Fix Windows Update corruption errors such as 0x80070002 and 0x80070057 to a dead end in the console with 'error 87' -- A few days ago I migrated my hardware to a new case. The components did not change. I did, however use different SATA ports for my optical, HDD and SSD. Windows booted, my apps ran, but my browser (chrome) began warning me that the certificates for websites such as chase.com and google.com had expired or been revoked. Microsoft websites msn.com and hotmail.com were not affected. I opened windows update and the date of the last scan was listed as never. I don't remember if I began the update process or not. If I did it must not have solved my problem because I decided to try system restore. The restore wizard railroaded me into a re-install and all of the info on my SDD was wiped after selecting the initial 'keep files' option. Windows Update succeeded in installing all updates but this one and I'm at a loss and feeling very frustrated at the apparent lack of control I have over my machine. Hell, just when fetching the CBS file for this post I figured I'd be clever and skip the 'copy to desktop' step. 'send to>compressed folder' is denied administrative permission and I'm the only user. As far as this machine is concerned I should be Jesus ****ing Christ. Guess what changing the file permissions to 'full control' for my user via properties>security does? IT LIES TO ME. *phew* It feels good to blow off a little steam. I appreciate your help and look forward to learning as much as I can from this site so these problems aren't so impossible to me anymore.
