A messy dump of some notes on figuring out what's wrong with Windows Updates. The security check against defaults is quite useful:
- fixed Windows Genuine Advantage on Assistant PC so IE7 and SP3 can install. i tried a few things, the one that worked was just going to a MS website other than windows update that requires the WGA activex plugin. shrug.
- still no luck - IE7 does not go.
- check log: SE_BACKUP_PRIVILEGE
- http://www.ss64.com/ntsyntax/security_groups.html -- backup operators is by default empty

Start/Run --> SecPol.msc
Then go to
"Local Policies > User Rights Assignment"
Verify that the "Administrators" group is a member of the following
policies:
Back up files and directories
Debug programs
Manage auditing and security log
Restore files and directories
Take ownership of files or other objects

Win7:
On multiple machines I have seen error 8024402c - the computer has been setup to get updates from a central server, which isn't working or isn't set up right. To go back to normal "Internet" updates:
KEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
Chage the value of the UseWUServer from 1 to 0
Restart Windows Update service
Win10:
First
Try the built in Windows Update Troubleshooter.
Second
Similar to others, SoftwareDistribution can be deleted.
See: https://support.microsoft.com/en-us/help/971058/how-do-i-reset-windows-update-components
I think the most likely bit is:
net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc (cryptsvc locks catroot2 folder in W2K8)
Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat"
Ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak
Ren %systemroot%\system32\catroot2 catroot2.bak
reboot (or manually restart services).

Windows 2008 (maybe others) it is SAFE to rename/delete the SoftwareDistribution folder - see https://support.microsoft.com/en-ca/kb/2509997
