A while ago my CPU started being taken up by seeminly random internal processes, causing slowdowns. However recently this has become debilitating. The Task Manager is unresponsive, as are windows explorer, the start menu and the task bar, for a short time after startup I can access the task manager and so on, but after a few minutes they stop working. 'Appmodel' seems to be taking up 100% of my CPU, ive tried to restart it and I get Error 1061. Ive tried restoring my files from a backup, but that has changed nothing. I cant even right click the recycle bin to free up some space. My laptops a couple of years old but not ancient, and im using windows 10
