Windows 8.1 Update has been available to download for a couple of days now but the installation process has been anything but smooth for many. Hundreds of posts have piled up on Microsoft's Answers forum regarding a myriad of errors associated with the update as highlighted by InfoWorld.

The majority of posters appear to be experiencing issues about a third of the way through the installation process. Errors 80070020, 80073712, 800F081F, 80242FFF and 800F0922 are all common and have cropped up while attempting to install the update or while trying to run the DISM.EXE diagnostic process.

Some users aren't getting specific error messages at all. As poster StefanA noted, the installation process quickly reached 74 percent then slowed to a crawl until it reached 89 percent. At that point, the installation aborted without a specific error message. A further message simply said the updates couldn't be completed and that Windows was undoing changes.

Microsoft has released a few fixes and workarounds but trouble still seems to persist.

It's a big problem in its own right but it's compounded even more when you realize the update is mandatory for all Windows 8.1 users. Users of said operating system won't be able to receive further updates from Microsoft starting next month unless they get Windows 8.1 Update.
