90% memory usage shortly after installing windows 10, I have very little open. My fan has been on full blast for a while now. Kinda similar to this guy.
But I don't have as high non-paged kernel memory value. I"m going to explore that result for now, can anyone else give me a good idea as to why its so high?
Don't worry, the high memory "usage" of the SYSTEM process is fine and by design. Instead of paging out data to the page file and (mostly slow HDD), Windows 10 compresses the data and stores it in the SYSTEM process.
Read my link for a much deeper answer.
To analyze the CPU usage of the Windows search indexer you have to use xperf. Install the WPT (part of the Windows 10 SDK), open a cmd.exe as admin and run this command:
xperf -on LATENCY+DISPATCHER+FOOTPRINT+VIRT_ALLOC+MEMINFO+VAMAP+REFSET+MEMINFO_WS -stackwalk VirtualAlloc+VirtualFree+PROFILE+CSwitch+ReadyThread -buffersize 2048 -MaxFile 2048 -FileMode Circular && timeout -1 && xperf -d C:\TEMP\HighCPUAndMemoryUsage.etl
If you have enough data of the memory usage grow + CPU usage (1.5 - 3 minutes), press a key to stop tracing.
Open the ETL in WPA.exe and analyze it for CPU usage and memory usage grow.
Just after the upgrade to Windows 10, the system re-index all the datas to make the system more efficient.
On computers that hosts a lot of indexable datas, it can take some time.
But when it will be finished, you will get back your memory and performances. the system will only index the new elements.
