System Update Keeps Showing Same Update

Question

Hi,
I just did a system recovery from the partition on a ThinkCentre MT-M 9636. The O/S is now back to its original condition. Before doing any MS updates, I updated the BIOS, downloaded the latest version of "System Update" from Lenovo, and have applied all the urgent/recommended updates. However, there's one update that keeps re-appearing as needing to be installed, even though it's already  been installed multiple times.
It's "Rescue and Recovery Critical Patch for Windows Update (KB917422) - Version 1.00.0005". In fact, I think I manually downloaded & installed it from Lenovo before I even ran System Update.
Any ideas why this is happening and how I can get around it? I want to make sure the machine has all the latest drivers/patches/etc. from Lenovo before I start the MS updates. Thanks in advance for any assistance.
Regards,
--- Gary

It sounds like the details which System Update has on that update which tells it when the update is already installed must be flawed.  You can manually confirm it is installed by checking the registry at this location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr​entVersion\Uninstall\{83E5061B-A69A-46AD-A780-1DA6​569FF283}
The DisplayVersion value should be 1.00.0001
