Quick fix steps

Frequently Asked Questions

Does this mean my PC can't handle Windows 11 at all?
Not necessarily — this is a general upgrade failure code that's often caused by an incompatible driver or third-party software, not a hardware compatibility limit. Checking PC Health Check separately confirms actual hardware compatibility.
Is it safe to just keep retrying the upgrade?
Repeatedly retrying without addressing the underlying cause (usually a driver conflict) tends to fail the same way each time — disconnecting non-essential peripherals and updating drivers first improves your odds.
