RAMMap v1.63 Empty Working Sets does nothing on Windows 11 26H2 (build 26300.xxxx). Worked fine on 25H2 before the September 2026 quality update

Hi ExoticGuest,

Thanks for explaining what happens. If selecting Empty Working Sets in RAMMap causes the whole PC to crash and force-restart, I’d avoid using that function again for now while we narrow down what’s triggering it.

When this happens, do you see a blue/green screen or any stop code before the PC restarts or does it restart immediately? Could you also run winver and share the full OS build number and confirm that you’re currently using RAMMap v1.63?

For now, I’d avoid using Empty Working Sets again if it’s causing the PC to restart. I’d also check Settings > Windows Update and install any newer cumulative update currently available for your build.

If the crash created a dump file, please don’t upload it publicly, since dump files can contain sensitive information.

Let me know what you find from the checks above and I’ll be happy to help you narrow this down further.

The screen turn out black , total black . appear bottom part of screen a long error , somehow by that long code error check something . . . also in middle of the screen goes a load count from 0-100% and then when reach its restart . . .

Version 26H2 (OS Build 26300.9550) and yes im ussing RAMMap v1.63 .

Exactly now i avoid use that option from the program . . . cause no matter if i use good ammount of ram or less . . . it goes to the black screen ! ! !

I miss that option to work . cause sometime it help bring back ram . Long time on pc like more 8hrs and ussing a lot of tabs . . . pc somehow get to not respond anymore or very very slow .

Hi ExoticGuest,

Thanks for confirming those details. Since you’re already avoiding Empty Working Sets, I’d continue doing that for now.

The black screen with the 0–100% progress is useful information. If it happens again, could you take a photo of the screen and share the stop code/error name shown near the bottom? You can cover or crop out anything personal before posting it.

That error should give us a much better idea of what’s causing the crash when RAMMap tries to empty the working sets.
