I just tried the latest update and encountered a different error. Seems MSFT Win 8.1 Update 1 is still not ready for prime time.

Windows 8.1 Update for x64-based Systems (KB2919355)
Installation status: Failed
Error details: Code 800F0922
System got to 89% then said it couldn't complete the updates and that it would back out the updates. 15 minutes later, I'm back where I started.
Is it possible windows defender or other virus scanner blocked this update?

There's a possibility that the user I was responding to may not have read them elsewhere.

New article with nothing new in it--same suggestions which you may find in virtually every thread in this forum.
Buck,
Microsoft has just published a new article to try and resolve installation issues. It might help, so go through those steps first before reinstalling: http://windows.microsoft.com/en-us/windows-8/install-latest-update-windows-8-1
Have you tried resizing your recovery partition? I know it's kinda risky as you mentioned, but it seems better to me than reinstalling Windows completely.
