I have a laptop that runs Windows 10. I don't usually shut it down or restart it. I do restart it occasionally. Prior to updating to Windows 10 version 1903 I had no problems with memory. But since it updated to 1903 forcefully, my memory goes up to %97 daily, then Windows lags horribly for 30 minutes, completely freezing every now and then, then the memory slowly starts to drop to below %50 and then starts increasing for about 12 hours and the cycle keeps repeating. I've updated my graphic's card driver, updated Windows again, googled for a solution, but couldn't find anything. Windows task manager doesn't show which program is using about half my memory, which is 16GB. Does anyone have an idea how to find the culprit?
