Otherwise some applications will not load the patch.

I suppose it's true for drivers installed by Windows Updates, not by bundle from Nvidia site. Right?

No, drivers from NVIDIA will need this patch.

As a followup, anyone using the DCH drivers must update these. Most users will have DCH drivers.

@doctorpangloss I noticed the same, were you able to patch the files in this directory? Seems like it might be harder than just running the patcher as System.

As an update, I have successfully patched these files by taking permissions of them.

Precisely, how should we patch these files, and what file ? Because, I installed the new driver, patched it, did the bump for limit. Using ffmpeg test i can start a lot of stream, but when I try plex transcoding, I'm still limited to 5

Install gsudo, then run the copy commands as Trusted Installer:

choco install -y gsudo
sudo --ti cp source.dll C:/Windows/.../destination.dll

Alternatively, use icacls to temporarily take ownership of the destination, then revert to trusted installer. Maybe consult ChatGPT for details.
