SOLVED: How To Block A Windows Update

We recently dealt with a series of clients who were having difficulty installing a January 2024 Windows Update KB5034441 because it inquired required the Windows Recovery Partition to be at least 200MB in size and they just didn’t have it.

If you’re working on physical machines, it’s not a problem to expand the partitions using a tool like WinFR Free or Partition Magic, but if you’re working on enterprise server is running on something like VMware you’re going to want to be a little more careful and several of our clients just refused to expand their WinPE partitions.

The patch in question only related to systems that had encrypted drives and we believe the hack that could use exploit the weakness in the original configuration required physical access. Our clients felt safe that physical access would be something hackers would not be able to achieve and none of them had or planned on having encrypted disks.

After a few months of waiting for Microsoft to release a better patch they announced that they will not be and that the only way to get the patch installed is to manually expand the partition so our clients were just unwilling to take that risk.

The problem is if you don’t get that patch installed it shows up and errors out every time you do a Windows Update which is quite annoying.

How To Hide / Block a Windows Update Patch

Years ago you could simply pick and choose the patches that you wanted to install but now you cannot with Windows 10 and Windows 11 cumulative updates.

  • Fortunately, Microsoft built a little tool called “Windows Update Show Hide” which lets you hide or show any pending Windows Update
  • Unfortunately, Microsoft has withdrawn that utility so it’s no longer available directly from them
  • Fortunately, it’s available from us as we still have a copy of the last version they released
