I have Win10 on a Toshiba Satellite laptop. The "busy" blue circle mouse pointer is constantly on. I had been using Win10 without this issue for months. It only appeared after I did a restore from a restore point that was just days old (which I created before trying to resolve a different, unrelated issue). My windows updates are up to date. I've rebooted several times.

What I don't know is, is this a mouse pointer issue or an actual busy process issue. I've monitored Task Manager. My McAfee real-time scanner was consuming 30% CPU (yet another new, I think unrelated, issue I have to resolve). I've turned that off, but the issue persists. Any time I look, overall CPU usage is at 45-50% with no one process ever consuming more than 8% tops. Since I wasn't in the habit of monitoring CPU usage I don't know if that number is normal or not while just running Outlook and Chrome with several windows.

The web is full of possible solutions. I've tried a few with no luck.

It seems odd this would only start after a restore back to a state where the issue didn't exist. Is this a clue? No idea.

Any thoughts, advice, links to diagnostic steps or "the" solution would be appreciated.

Update: Issue appears to be caused by a Java update, specifically the update notification pop up of all things. See below for more info.
