My computer has 8gb memory and always used up to 96%memory, I tried so many method and finally I have ended the process of coreServiceShell in Resource Monitor, the Physical Memory recovered immediately from 86% to 43%, I think it is a virus. dL
I had increasing memory usage (coreServiceShell.exe) on powering up my system recently. Also same issue with windows media sharing service. So I disabled WMSS and coreServiceShell.exe behaved itself - problem solved (I think) Peter H.
CoreServiceShell.exe is the PRIMARY guts of TrendMicro AntiVirus software and should never be deleted if someone has installed a legitimate copy of TrendMicro. As far as not being essential to Windows, it may not come from Redmond but it protects Windows far better than MS Security Essentials could ever hope to. Robert Weaver, 52 year retired IT
According to me, "the Trend Micro" is the best antivirus I've ever accidentally installed. Much because of I don't have to care, the program will automatically remove most threats. When it comes to coreServiceShell.exe it helps a lot when Using programs like, "Tunngle" or "Hamachi". To automatically create the "links" rather than fiddle with port forwards. Malcom

It randomly starts using 50% or more of my cpu and slows my pc down for 20-40 minutes at a time. When it starts doing so, I have no choice but to wait and hope it stops because Task Manager cannot kill the process I have used file.net

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command.
