erhm.... seems like that process "Shootergame" is eating up your disk performance. Maybe it is best to look at this particular process.

I tried to google it: http://steamcommunity.com/app/346110/discussions/0/594820473979122823/

good luck

even if I don't have starded that game its 100 % and if 15 mb is used by that it wouldn't be 100 %

I know that game: "ARK: Survival Evolved". If this happens regularly, check your disk for bad sectors with 'CrystalDisk Info'.

Yes but if I end it , my disk is 100% sometimes on the moment I run steam and windows edge and my disk is still 100%

I suspect that you don't understand what you're looking at. The disk column in the task manager shows MB/s for each process. Megabytes per second, not just megabytes [*]. It's the disk read/write throughput, how much data is read or written each second, not how full the disk is. 100% means reading/writing is occuring at the maximum rate the disk supports. Which is good, you want processes who do lots of disk input/output to be able to use the full speed the disk supports. You did not say your computer is terribly slow, so do you really have a problem?

If you really have a problem, a site like http://answers.microsoft.com/ is more appropriate for your question. This website is about computer security, not specifically about Windows and not about every aspect of using Windows, just security. Your question does not seem to have anything to do with security, it's more about performance or about interpreting the taskmanager user interfacce. Asking your questions in the right place probably gives you better answers and helps to keep other forums on topic.

[*] Try to be exact when reading and writing units, please. The /s part changes the meaning completely. And mb is not the same as MB, m = milli, M = mega, b = bit, B = byte. 15 mb is 15 millibit, not 15 megabyte. ;-)

If you have Nvidia cards in a SLI setup on Windows 10, then Nvdia just released an update to fix this.
