I have a serious memory leak issue that has been going on in my system since March of this year.
Since I upgraded to Windows 11, the lsass.exe program has been leaking memory slowly over the course of a six-hour period before the virtual memory reaches 99%, causing my PC to crash and forcing me to restart the system to bring it back down.
From my research and patience, I have found no such solution to this issue except for 22h2 systems, which this is not.

i found this from Dell.

which seems to indicate it could be caused by Dell Support Remediation software.
also other reports of corrupt drivers and recommendation was install drivers direct from manufactures web site.

the other one was Vram. maybe changing the Vram cache settings.

not much of a help but it is a start until MS come out with a fix.
best of luck. Steve ..

Yeah, I've had these pages saved on my browser for a long while now. When I said I've been doing a lot of research for this issue, I meant it.

Neither of these have helped me really at all, and that first one only applies to 22h2 systems, which mine is not.
It has great ideas for sure, but none of them here either apply to mine or help the issue dissipate.

this is a bit of out of the box thinking and a very old'ish trick.
the only trick i can think of which used to help with leaks and memory loads is to unload the DLL's
this is meant to done auto on Win 11 but i have found on occasion that its not always as auto as it should be.

as stated its out of the box thinking and could very well not work.
you can delete the reg entry afterwards if it is of no help.

best of luck. Steve ..
