Yeah the regedit didn’t work for me either.

I'm on Big Sur beta 6 from internet recovery last week - have bootcamp eGPU working on bootup using 1903 v1 with ms hotpatch and windows updates disabled using april red bootcampdrivers... I'm gonna ride this setup until it stops working.  I'm afraid to even try the new bootcamp drivers lol.

To follow up: The registry edit did not work, but replacing the pci.sys file with the one provided by @Shiraz at the below link, works fine in the latest build of Windows 10:

Could Big Sur really be the issue why I'm unable to get my eGPU working on any of the OSes on my MacBook? I have Big Sur as my main OS, it was confirmed to me that automate-eGPU EFI won't work with Big Sur (and since I have R9 280 I can't even use purge-wrangler) so my eGPU is totally useless there, but also on Windows? I thought the error 12 was just something difficult to get rid of, but after following the guides, it's just not going away.

Does anyone have any REAL working method to STOP windows updates?  every single time I boot into my 1903 v1 install .285 build it immediately starts installing updates in the background... I have to boot back into parallels and uninstall the update each time in order to get my eGPU to work in boot camp again.  I have tried disabling/deleting the windows update option in task scheduler, disabled "windows update" service in services.msc, applied the no windows update patch in the registry and used the local GPO editor to block updates - even tried setting up a fake WSUS so it cannot connect and get updates... sheesh it's just ridiculous how persistent it is to update when I don't want it too.  🙁

So to be clear with your signature that could have updated by now - you are running bootcamp win 10 v2004 (stable, not fast ring) with the pci.sys hack while using Big Sur beta 9 without any problems? Smile What version of drivers are you using for your 5700xt?  bcd april red?  Does it boot up properly every time or do you have to port dance or hot plug, etc?

I think I might just update Big Sur past beta 6 and update windows completely to 2004 and use the pci.sys to avoid all these windows updates I'm fighting Smile

@erik_tank, I’m nervous to suggest this as I’m not 100% sure it stops all updates, I think it does, but it’s been a while since I had to do so (current build works fine with new windows) - set your home WiFi as a metered connection and then don’t allow downloads over metered connection.

Yeah that's a pretty sneaky way - I'm just not sure if it'll cause problems with latency or network traffic... I use my eGPU in bootcamp to play VR wirelessly Smile

I tried updating to 2004 today, latest updates, no dice for my system.  Tried replacing the pci.sys file from my previous 1903v1 build which works, and I get a BSOD at startup.  

So I'm sticking with 1903 and fighting windows updates for now I guess.  Hopefully the metered connection trick works.  Thanks Smile
