Windows 11 22H2 Update BSOD on Steam Deck

I can't Upgrade Windows 11 21H2 to 22H2 on my Steam Deck. Always i got BSOD (Bad Pool Caller) while Upgrading. I have Dual Boot Windows 11 + SteamOS on Steam Deck.

I found this:

BAD_POOL_CALLER, also known by its BSOD STOP code 0x000000C2 (or 0xC2), means that the current processor thread is making a bad pool request. What does that mean? It could point to a situation where a piece of software tries to use a processor thread that isn't available because a different program is using it.

I would treat it as unsupported computer and upgrade it using the appropriate hacks. The easy one is to download the Windows 11 22H2 ISO and use Rufus to create a bootable USB flash drive. When prompted by Rufus make sure you check all the boxes to remove ALL compatibility checks. Also disconnect from the Wi-Fi during the upgrade to avoid any hidden online compatibility check that might affect the process.

The manual way is to copy the ISO locally or connect the USB flash drive containing it. Disconnect from the Wi-Fi, mount the ISO (Open with File Explorer) and run Setup. Wait until you see the first Setup screen. Before proceeding enable showing hidden files and not hiding known extensions. Then right-click on the desktop and create a new Notepad file. No need to open it, just rename it to appraiserres.dll without the .txt extension at the end. Now browse to the hidden folder C:\$Windows.~BT\sources and delete the original appraiserres.dll file. Now copy-paste the fake file you created on your desktop into the folder. If you see any UAC confirmation while doing these, just reply YES and input your password. After you have replaced the original file with the fake, you may proceed with the upgrade, any compatibility checks are removed, DON'T connect to the internet until the upgrade is completed and you are at 22H2. You can confirm that in Settings->System->Info

Whatever method you choose, better also to keep disconnected from the internet. I have confirmed with at least five unsupported computers that staying online will make the upgrade fail somewhere in the middle of the first stage, before even the first restart. I believe this is due to some hidden online compatibility check. Staying disconnected from the internet cannot do this check and block the upgrade, so it just allows Setup to proceed as normal. After a successful upgrade to 22H2 you can reconnect to the internet and download the rest Windows updates.
