Windows 10: High CPU and RAM use by Lanmgr Server

This is not good.


The svchost.exe hosting lanmanager server is using up 2.5 mb per second.

This has started around 2020-08-11 with the windows update.





I can kill the process but it will be reborn to eat more memory...

RAM leaks and high CPU usage

Sorry to seem so negative, folks, but am I the only one who thinks it's disgraceful that the onus seems continually to be on users to fix the ridiculous RAM leaks and high CPU usage problems that were caused by the Fall 2017 Creators Update?

I received the Creators Update for Windows 10 Pro near the end of the year -- not surprisingly, since I'm currently living in eastern Europe. Installation went smoothly, but from the outset, I began experiencing significantly higher RAM and CPU usage. These
were issues that I'd not experienced before. I did a bit of research, and discovered that the errors don't really seem to depend on system hardware or idiosyncratic configurations. Instead, the problems appear to lie clearly with the update itself.

I'm lucky enough to have a very robust system: i7 Haswell-E 5820, factory overclocked and liquid-cooled; 32 GB of RAM; GTX-980; fast SSD as my program drive, etc. I also have a Rainmeter skin that shows me RAM and CPU usage in real time. On boot, I used
to see only about 2.25 GB of RAM being used; CPU would settle to 1-2%. Since the Creators Update, RAM usage on boot is routinely from a low of about 4.25 GB to as much as 7.5 GB, and CPU usage regularly shows prolonged inexplicable intervals of 20 - 35% usage,
and occasionally even more.

I've tried the various suggested measures to alleviate the problems, with minimal (and only temporary) success at best. I've had no success at all in trying to get information directly from Microsoft through Support. It's worth noting that all the various
suggestions to deal with these problems involving taking steps to cripple Windows functionality in order to reduce system overheads, thereby depriving users of some of the very benefits the OS is supposed to provide. Microsoft doesn't seem to be bothered by
that; in fact, it seem quite content to allow users to flounder around in the mess created by the update.

Does anyone have a definitive solution for the RAM leakage and CPU usage problems (short of turning to an alternative OS)? Is there any word as to whether Microsoft will address these problems soon?

RAM has unusually low frequency and CPU usage is high

Hi Tim. I'm Greg, an installation specialist and 9 year Windows MVP here to help you.

Test the RAM overnight to stress it with the best bootable test memtest86, following these steps which test both the sticks and the slots:

Compare the install you did with this gold standard Clean Install of Windows which will stay that way as long as you stick with the tools and methods given, has zero reported problems, and is better than any amount of money could buy:

The reason I ask you to do this is because no one of millions who have followed the install in that link have ever come back to report problems that I have seen. It is also a great learning experience that will make you permanently the master of your PC because
you will learn what works best and have applied it with your own hands.

If you're confident in the install then go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done:

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account. Then continue
with the other steps to go over your install most thoroughly.

I hope this helps. Feel free to ask back any questions and keep me posted. If you'll wait to rate whether my post helped you, I will keep working with you until it's resolved.
