On a regular Windows Update routine I'm getting the following message:
We couldn't complete the updates, undoing changes.
The computer restarts for several more times repeating the same process, then, after system is on, checking the updates history reveals this:
Security Update for Windows 10 for x64-based Systems (KB3074683)
Failed to install on [date]
Checking the event viewer, I see this error 4 times:
Installation Failure: Windows failed to install the following update with error 0x80070003: Security Update for Windows 10 for x64-based Systems (KB3074683).
