System and compressed memory

[Peter Koppa]

Hey,

My Windows 10 updated itself recently and I noticed that I have a process named "System and compressed memory". This process uses up a lot of HDD occasionaly, making the PC unusable.

As far as I could notice it well, it uses a lot of HDD when I'm downloading. Why? I don't think it happened before.

Is this a clean installation of Windows 10 or an upgrade for your previous OS? Please state the previous OS if this was an upgrade. Please state your full systems specs so we can verify you have undergone BIOS updates or if they are needed.

Regarding your high HDD usage you can try and perform a system restore to a point prior to your update and see if the issue is alleviated. Please be sure to back up your critical data in case something goes wrong.

A real world scenario is where the HDD, RAM and CPU are taxed but if either one is taxed or is taxed too high then it is a glitch within the OS. The usual glitch is the issue with too much ram being used by "services and compressed memory".

Upgrade of my previous os. My previous OS was Windows 7 Ultimate 64 bit.

My system is:
Intel Core i7 3790
Gigabyte Z97P-D3
Gigabyte G1 Gaming GTX 970
Corsair VS550
2x4 GB Kingston HyperX Blu 1600Mhz
WD Caviar Blue 1TB 7200rpm SATA3 HDD

I tried reinstalling Windows 10 from a DVD but the installation seems to get stuck at 66% at "Preparing files for installation". The HDD activation LED indicates that it's working, and also the DVD player LED, but it does nothing. I waited for 35 minutes, but it didn't make any progress, so I reinstalled my Windows 8.

By the way it uses too much ram I think too, because it was around a 1 GB or something. But I didn't really care about that, because I had plenty of free ram. However the high HDD usage ruins gaming, and even downloading. Before the update I could download with 30 MB/s. After it, according to the Task Manager, the downloader app (Chrome) was downloading with 14 MB/s, and using that much HDD, meanwhile "System and compressed memory" used about 20 MB/s HDD. After the download finished the "System and compressed memory" also stopped using HDD. Interesting. In GTA V in a car I had about 20 FPS on places where I had 60 before in car, but if I was standing and the computer wasn't loading, then I got 60 FPS, so it's definitely the problem of HDD.

So I don't know what System and compressed memory is but it doesn't work properly. At least for me.

When encountering problems caused soon after a Windows update its best to do a system restore. The OS's files have been corrupted thus the issue otherwise what has been included in Windows 10 is necessary for its functionality.

I gave it a try and install Windows 10 again. The same situation. Perhaps it's only for me then. :/

System and compressed memory is Superfetch. Sometimes it works fine, other times it thrashes around the HDD. Over time it will calm down.

If you want to disable it, just go to Services and disable it.

It may be the "Killer Network Manager" software. If you uninstall it, the issue goes away, but so does network as it uninstalls the network adapter drivers as well. The good new is, there is a fix.





First, go to http://www.killernetworking.com/support/driver-downloads/item/killer-suite and download the new version, but do not install it yet. Just save it and know where the file is located.





Then, uninstall the current version through the control panel. You will have to restart the computer. Once the computer is back up, run the new software installer. The new version that was released January 2016, doesn't seem to have that same issue.





Just a FYI, the "Killer Network Manager" software is part of Qualcomms Aethos Killer Wireless-AC / Wireless-N and wired E2200 / E2400 network cards. Without the software, you have no internet.

UM, No, it does not stop system and compressed memory when you disable SuperFetch, all it does is disable SuperFetch and system and compressed memory still runs notskrnl is the key component for system and compressed memory, If you are not apart of the solution then you are a part of the problem...
