[SOLVED] Code 1 Windows Update encountered an unknown error - Win7 x64

Let's try this.

Delete Registry Key



  1. Click on the Start button and in the search box, type regedit
  2. When you see regedit on the list, right-click on it and select Run as administrator.
  3. In the left hand panel of regedit, you will see a list of registry keys. Navigate to the following key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\ApplicabilityEvaluationCache
  4. Right-click on it and select Permissions...
  5. Click Add.
  6. Click Advanced.
  7. Click "Find Now".
  8. Scroll down and double click on Everyone.
  9. Click OK.
  10. Single click on Everyone and then tick the "Full Control" box under Allow.
  11. Click OK TWO times.
  12. Right Click on the key ApplicabilityEvaluationCache and choose Delete.
  13. Click Yes.
  14. Reboot.
  15. Try updates.

In your next reply, please confirm that the key was successfully deleted, tell me if there are any changes in regards to the error try updates and attach CBS.log if they fail.

It's 3.15 A.M. here and I'm calling it a day. Good night.

I'm sorry. There IS an ApplicabilityEvaluatinCache key. I am unable to change the permissions on it. "TrustedInstaller" is the only account with Full Control. Logged on as Administrator, I am unable to change permissions or delete the key.
 
FRST Fix
NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system
1. Please download Farbar Recovery Scan Tool and save it to your Desktop.
Note: You need to run the 64-bit Version so please ensure you download that one.
2. Download attached file and save it to the Desktop.
Note. It's important that both files, FRST64 and fixlist.txt are in the same location or the fix will not work (in this case...the desktop).
3. Run FRST64 by Right-Clicking on the file and choosing Run as administrator.
4. Press the Fix button just once and wait. If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
5. When finished FRST64 will generate a log on the Desktop (Fixlog.txt). Please post the contents of it in your reply.
6. If the fix succeeds, attempt the update again.

Updates still fail......
 
The manual installation attempt failed. Please see the attached cbs.log file. The date and time stamp don't appear to have been updated since the most recent attempt at installation.

Re-booting with the anti-virus software disabled did not fix the issue. Our A/V software in our vSphere environment is agentless, so there really isn't a way to un-install it. There were four other security updates that got installed on my most recent attempt at windows updates. This is really perplexing. I have never experienced an issue like this in over 20 years of working on windows/computers. I am starting to think about just waiting for the May cumulative update to see if that works. And if that should fail I am thinking about creating a brand new OS layer for the VDI environment, although that is quite the task and requires re-creating all of our application layers also.
