What part of WinUtil are you having issues with?

Tweaks Tab

Provide a clear and concise description of the issue.

Description
After running WinUtil (Tweaks tab, “Standard” preset) on a friend’s laptop, Epic Games titles using Easy Anti-Cheat stopped launching. EAC now shows:

Easy Anti-Cheat
Untrusted system file
\?\GLOBALROOT\Device\HarddiskVolume3\Windows\System32\amdlhk64.dll

This started right after the WinUtil run.

Environment

  • Laptop: ASUS
  • CPU: AMD Ryzen (4th gen)
  • GPU: Nvidia RTX 2060
  • Storage: NVMe SSD + HDD
  • OS: Windows 11
  • WinUtil preset used: Standard

Steps to reproduce

  1. Run WinUtil (irm https://christitus.com/win | iex)
  2. Go to Tweaks tab, select the “Standard” preset, apply
  3. Reboot
  4. Launch any Epic Games title that uses Easy Anti-Cheat

Expected behavior
Game launches normally through Easy Anti-Cheat.

Actual behavior
Easy Anti-Cheat blocks the launch with “Untrusted system file” pointing to amdlhk64.dll.

Question
Has anyone else seen EAC/anti-cheat “untrusted file” errors correlate with running the Standard preset?

List the tweaks you applied before the issue occurred.

Discord: alexmini: <@1471554971081113836> One thing I forgot to mention: during the run, the console said the tweaks were finished, but there was still a window open (looked like the disk cleanup, i don’t know for sure) that seemed stuck near the end. Since the console already said everything was done, I force-closed that window with the X button instead of waiting or cancelling it properly. Not sure if that’s related to the issue, just wanted to mention it in case it helps.
