All this sounds wonderful but my laptop keeps telling me to reset my TPM every other time I start it up. I found that the reset shown above does NOT resolve the problem but if I just reboot the laptop the TPM suddenly starts working like magic. This seems to be some sort of issue in Windows 10 1803 as it never appeared before the last update 1709.
I have two ASUS ROG laptops and they both do this behaviour. Restarting always fixes it.
^^ Have you tried FIX 2?
Hi
I have the same problem and in windows defender it can be fixed following the instructions but it says ‘back up your computer as you may lose data’ so of course I have not backed up ever so it puts me off doing the fix. I see that you did not warn of this possibility above so do I assume I will not lose data or that I will?
^^ Thanks for pointing it out 😊 I’ve added the warning now. Make sure you backup first and then clear TPM.
