Windows 10: Local Security Authority Process extremely high memory and disk

A couple of weeks ago, LSAP started taking up around 10-20 gb of memory, and logging in also started taking an insane amount of time. However, after around 10 minutes of being logged in, LSAP goes down to around 1/2 gb. Is there any reason why LSAP should be taking up that much memory, and is there any way to reduce it?I am running Windows 11 Pro 21H2

System and compressed memory high disk usage during file copy

Thank you Amarjeet_Paul.

I spent many more hours than I had hoped this past week reading and trying others' suggestions from this community on how to reduce high RAM usage due to ntoskrnl.exe. The "System and compressed memory" process remained the top consumer of RAM, using 500-900MB,
among all other processes running. I deemed it to be the likely culprit in making my computer use frustratingly sluggish. After completing your
third step, steps 1. & 2. provided no improvement in my case, the "System and compressed memory" process RAM usage has plummeted from the top of the Task Manager Process list to the bottom, running at a remarkable 0.1MB! That's a whole lot less than
1% of the targeted process' gluttony. You're hired! Ps. I'll be keeping an eye on the process' use as I get back to normal operations, and be back if it floats to high in the list. Or if the registry fix you suggested has compromised use in any way. Please
explain in simple terms what the insertion of your registry modification is doing.

Thanks again.

Geoff
