By almost nothing, I mean Firefox, & some background network applications that are entirely passive và would never use this much memory.

Related services: UxSms, TrkWks, SysMain, PcaSvc, Netman, CscService, AudioEndpointBuilder, TabletInputService

The only thing I can think of is that I was running Virtualbox with Ubuntu for a little while but that is limited to lớn 2GB of memory & it"s no longer running.

Edit: I am most interested in the question of why/how? Likely a leak somewhere but given the services listed above, do any stvà out as being a potential culprit?

svchost.exe pháo is the process that runs all your Windows services. One of them has gone mad apparently. Right-cliông xã on svchost.exe cộ and select "Go to Service(s)". That will tell you which service it is, and you can use Services Manager to lớn restart or disable it if you don"t need it.

This happens after updating to Windows 7 Service Paông chồng 1. Memory leaks can happen when the background service for Windows Update (netsvcs) is enabled. You can find more info here, among other places. See Awa"s answer here lớn verify that Windows Update is at fault.

One inelegant solution lớn this issue is khổng lồ turn off Windows Update và install all updates manually. Run services.msc and phối Windows Update & Background Intelligent Transfer Service khổng lồ Disabled. See here for general instructions on services.

However, several updates lớn fix this issue have sầu been rolled out by Microsoft. When you first run Windows Update in a new installation of Win7 SP1, it will insist on installing Windows Update Agent 7.6.7600.320 (KB2887535), before it lets you check for other updates. Let it bởi vì so or apply the update manually if installing offline. After doing so, you might not be able to install other updates automatically until this issue is resolved.

Then, manually download và install the following update:

https://tư vấ

This updates the Windows Update Agent lớn version 7.6.7601.18979.

This is the newest update in a series released by Microsoft khổng lồ address the issue. Each has been replaced by a newer version, and it seems that you only need to install the newest one. However, if this does not fix the issue, you can try installing an older update in the series, or perhaps install them all sequentially. In chronological order, consult the following updates: (June 2015) (July 2015)https://tư vấ (August 2015) (September 2015)

Then, according to this answer, install this update: (20-Oct-2015)

This updates the WUA lớn version 7.6.7601.19046. Theoretically, you should be able to lớn just skip khổng lồ this step & be fine. However, this update claims to not replace earlier updates, which is why it might be advisable khổng lồ install the aforementioned update(s) first.

Lastly, it might be advisable to lớn disable the two aforementioned services before manually installing these updates, then re-enable them afterwards. I think you should be fine either way, though you might want khổng lồ restart your machine after each update, just to be sure.

Reports vary, but this should fix your troubles with Windows Update hogging memory & CPU :)
