TL;DR
- Make a copy conhost.exe from System32.
- Open it with a hex editor (I use HxD).
- In HxD, go to Search - Find - Hex-values.
- Search for 881d9e530a004885c07477ff15b32e08009084c0.
- In Windows 10 version 2004, replace ff15b32e0800 with 909090909090. If using Windows 10 version 20H2, replace ff15b32e08009084 with 9090909090909090.
- Save file and copy it back to System32 (take ownership of original conhost.exe in order to replace it).
- Profit!
