Windows Server 2008 R2 Standard - Cannot download Windows Updates

I'm attempting to update a production server that hasn't had a Windows Update installed in almost 3 years.

When I attempt to download any update, even if I select just one, the download hangs at 0% consistently. The first time I downloaded the updates (97 updates), it hung at 46% for 12+hrs.

I stopped the download, restarted the computer, restarted the Windows update, and ever since then, it hangs at 0%.

The event log is indicating that the installer, TrustedInstaller.exe, is crashing everytime I try to re-download the updates.

Faulting application name: TrustedInstaller.exe, version: 6.1.7600.16385, time stamp: 0x4a5bc4b0

Note: The other day, it let me know that I would need to download an update to the installer before installing Window's updates (humourous).

I ran this, and I'm not sure if it was successful or not, but I would assume so, since I was able to start downloading the updates up to 46%.

At this point I'm wondering if I should just install SP1 directly on the server. I assume it's a roll-up of all the major updates since, but I could be wrong.

Check your windowsupdate.log (C:\Windows) for errors.

Stop Windows Update and BITS services

Delete C:\Windows\Software Distribution folder

Reset your WMI Repository --> Open CMD and type winmgmt /resetrepository

Start BITS and Windows Updates services

Try again.
