cachecpu-cachememorywindows 8
I am having the following problem: I am having a completely new Notebook with 8 GB RAM and Windows 8. I do not use software that requires a lot of RAM and I do not have a thousand programs running. Despite, Windows keeps on complaining about the fact that I would not have enough RAM available. When I checked this via Task-Manager I saw that I only used 1.5 GB RAM and the rest was "used as cache" whatever this means.
My question is now: Is there any way to get my RAM from this cache-guy back?
actually you can click on the 'Show processes from all users' at the bottom left corner of the task manager to see a clearer picture. it seems to be a system process eating up the ram. you can also try using the Process Explorer tool from Sysinternals.
I also have this in Windows 8 as you can see in the xperf Trace I captured and viewed in WPA:
There is no fix for this because the memory usage comes from the WindowsUpdate client DLL when it scans for Updates (wuaueng.dll!CAgentUpdateManager::FindUpdates). The rest of the memory usage comes from loading the Update database C:\Windows\SoftwareDistribution\DataStore\DataStore.edb into the RAM.

Clear your ram cache with RAMMap's emptystandbylist option.

Alternatively, wj32 (writer of Process Hacker at sourceforge) has written a small cmdline app to do the trick. Find it in this thread.

Have not found a way to do this from Powershell yet, but if you are a good programmer you can find what you need in the source code of Process Hacker.
