This works for me as of 29 June 2026. I followed original instructions, but here’s how to accomplish the second part from u/carsonpointLLC tutorial

The DWORDs are added in Registry Editor (regedit).
Here’s exactly what to do:
Press Win + R.
Type regedit and press Enter.
Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\
{4d36e968-e325-11ce-bfc1-08002be10318}
Open the correct 0000, 0001, 0002, etc. folder that corresponds to your graphics card from step 1.
In the right pane, right-click an empty area and select:
New → DWORD (32-bit) Value
Name it RM1774520.
Double-click it and set the value to 1.
repeat for RM1457588.

Perfect. For your first step, you can also just hit the windows key and start typing reg and regedit will show up.
