Autopilot.dll WIL error

Looks like the fix is to reset the TPM!! Woo-hoo!! I wasn't using bitlocker, but understand that more complexities are involved.

I reset it via typing "tpm.msc" in the search area to the right of the start menu symbol.

You are then forced to re-enter your Microslop password again and afterwards re-entering your PIN...

Hi Pekaaa1:

I finally tried clearing my TPM as instructed in the MS support article Troubleshoot the TPM (i.e., Windows Defender Security Center | Device Security | Security Processor Details | Security Processor Troubleshooting | Clear TPM) and this appears to have stopped my ModernDeployment-Diagnostics-Provider / Autopilot.dll WIL errors. See my 03-Mar-2023 post on page 2 of in SageGhost's thread AutoPilot.dll WIL error was reported Event 1010 - Causes Crashing/Issues Any fix? for further details. I'll monitor my Event Viewer for a few more days and will post back if the errors start up again.

I do not have BitLocker disk encryption enabled on my Win 10 Pro v22H2 laptop so I did not need my 48-digit BitLocker encryption key to re-boot my machine, but like MisterFlamp, I did have to reset my Windows Hello PIN to sign into my device. That didn't go as smoothly as I expected, but that was partly my fault because I use two-factor authorization (2FA) to protect my Microsoft Account from unauthorized changes and have 2FA set up so that the 6-digit verification code is sent to a secondary e-mail address instead of my phone number (it's hard to read your emails when you're stuck on your Windows login screen :-)). I was eventually able to retrieve my verification code and reset my Windows Hello PIN (see my comments in SageGhost's thread) and all is well now.

I have the same issue as reported below

this has resulted in a 3rd. party installed CRM system repeatedly crashing over a number of months. No reported errors elsewhere and not being a computer boffin I am reluctant to fiddle.

I have in the past day removed my 2Tb WD external hard drive from the USB and the CRM seems to be behaving.

Have MS developed a solution????

Unfortunately I have limited computer expertise. That being said; I snooped around and learned this was added to my system 10/16/2022. That’s about the time I updated from 21H2 to 22H2.

I found onecoreuap when I did a search in Windows system32 directory looking for onecoreuap.

When I click on properties; due to my limited knowledge and not understanding what I’m looking at, I noticed when I clicked on “Details” at the bottom it displays “Remove Properties and Personal Information”. Needless to say I didn’t click on it since I don’t know the consequences.

I don’t know if this information is of any value or means anything. Possibly someone more knowledgeable can sort it out.

i am showing same hundreds of times per hour as well.....
