I'm watching 4k movies on a Samsung TV (as a monitor, Win11, HDR10+) with MPC-HC + madVR and every few minutes it freezes for about 4 seconds. I have a RTX 4050 laptop (Asus TUF A17).

I have had this problem in the past (like last year) and solved it somehow, but I cannot remember exactly what I did (I'm not very tech savvy, but I'm good at finding guides and subreddits to follow instructions, also some AI).

Any ideas what could be causing this? I keep trying everything I find and it doesn't seem to solve it (tried resetting MPC-HC and MadVR settings to default, then playing with different options, but did not work). It only stutters when I use madVR or MPC Video Renderer as the DirectShow Video output (the others don't freeze like this, but they are very bland and pale, I suspect it's because they ignore the HDR? Using them is not an option).

Some games that I've played and uninstalled after (from their own folder by running the uninstaller.exe) still remain here in the windows 11 Installed Apps section. If i press the Uninstall button under them, it gives me an error ("Windows cannot find... [specific game's folder]/unins000.exe").

Is there any way to get rid of these? (without installing the games again then uninstalling them from here... that would take tens of hours)
