Code 80070246 Windows Update encountered an unknown error

Applies To:
Hi.  I've reviewed other threads but this seems to be different.  

Get "Code 80070246 Windows Update encountered an unknown error".  It is Windows Update itself that is failing.  The PC runs Vista Ultimate and was until recently up to date with all recommended updates.  Windows Update now shows:
- Most recent check for updates: Never
- Updates were installed: Never
- "Windows could not search for updates" Code 80070246 Windows Update encountered an unknown error

Can Windows Update be uninstalled and reinstalled?

Answer

Hello hhmcaust,

Thank you for posting.  System resources, such as file data, registry data, and even in-memory data, can develop inconsistencies during the lifetime of the operating system. These inconsistencies might be caused by various hardware failures or might be caused by software issues. In some cases, these inconsistencies can affect the Windows servicing store, and they can cause software updates not to work. The System Update Readiness Tool tries to resolve these inconsistencies.

I am providing you the link to be able to download and run the System Update Readiness Tool.  This should correct your problem.  Here is the link:

Let us know if this resolves the problem.

Thanks,

Jack
