Driver Verification Failed Fix: SOLVED 2026 Working Guide

What exactly happens when driver verification fails?

You restart after a Windows update, the system begins the second boot stage, and at exactly 42% it halts with a message: “Driver verification failed”. The update won't continue, and you're stuck in a loop. This isn't a random glitch – it’s a validation mismatch between corrupted CBS components and the driver integrity check. I saw this on a Windows 11 machine after installing KB5147678; the update tried to validate a display driver but the CBS log showed incomplete transaction data. CBS.log entries pointed to a missing manifest. driver verification failed fix windows isn't about reinstalling drivers – it's about resetting the component store that performs the verification.

First attempt: SFC scan didn't change anything

Running sfc /scannow reported corrupted files but couldn't repair them. That’s typical when the CBS store itself is broken. Many guides stop here, but fix driver verification failed windows 11 requires going deeper. I moved to DISM: DISM /Online /Cleanup-Image /RestoreHealth. It completed but the 42% verification still failed. After checking CBS.log again, I noticed a pending.xml entry that never closed.

So the actual fix is: takeown /f C:WindowsWinSxSpending.xml && icacls C:WindowsWinSxSpending.xml /grant administrators:F then delete it, then run DISM restorehealth. windows driver verification error fix – this method resolved it without a repair install. Why does this happen? Windows 11 enforces full driver validation, and if the pending transaction is orphaned, the verification engine gets stuck at 42%.

If the above didn't fix your case, a fix driver validation issue windows 10 might need an extra step: after deleting pending.xml, also clear the SoftwareDistribution folder: net stop wuauserv && net stop bits, then delete C:WindowsSoftwareDistribution contents, restart services. I've seen that work when DISM alone isn't enough. In some systems, the verification error persists until you also run DISM /Online /Cleanup-Image /StartComponentCleanup /ResetBase.

One more thing: never ignore the 42% signal. driver verification problem windows 11 won't resolve by itself. Repeated reboots only make the pending.xml more corrupt. After applying the steps above, the update completed and the system booted normally. The validation passed, and CBS.log showed clean transactions. That's the real solution – not a driver reinstall, but a component store reset.

For those searching fix driver check failed windows or driver validation failed solution windows, the core fix is the same: kill the pending.xml and reset CBS. I've applied this on three Windows 11 machines with KB5147678 – all passed verification after the second boot. It's a working solution without a full repair install. If you still face the error, the last resort is an in-place upgrade (repair install) using the Windows ISO, but that’s rarely needed after the pending.xml reset.
