I have a fairly new windows 10 laptop that I've been using, and today it was running very slowly. I opened up my task manager and found these background processes that are collectively taking up almost 100% of my cpu usage, but I'm not sure what they are. I ended those tasks for now but I would like to know what they are in case they ever come up again.

One of them is called ".▯▯▯000600000007bef01a39bf74345ff998" and when I click on "open file location", it leads me to the recycle bin which is empty.

Any ideas on what they might be used for?

    Is it running updates? Could be if new. Let it run, let it update, let it finish, restart and test. Then run a full Virus Scan with Windows Defender. A decently set up Windows 10 machine should use less than 5% CPU more than 95% of the time. – John Jun 17 '21 at 17:35
  • it's about 3 months old, and I don't think it's running updates. I will try the restart and full virus scan that you mentioned – Brent789 Jun 17 '21 at 17:40

    If you are suspicious of the task I would perform a Reset on your installation. Since you cannot identify the process I would choose NOT to keep your personal files. Be sure you backup your personal files. – Ramhound Jun 17 '21 at 18:03
  • There is less than a 0% chance those processes have anything to do with Windows Update – Ramhound Jun 17 '21 at 18:04

    Yup - looks like you got scammed by the botnet already - maybe download fewer hooky games/pron. Nuke & pave, don't take anything across to the new install, let it all burn.

If you want to keep your existing install as is, because the machine is new, try reviewing CPU usage.

For reviewing Windows CPU and Disk Usage (as a minimum) run Windows 10 Admin Tools, Resource Monitor.

Let it run for 15 to 20 minutes and see what is using CPU and Disk (this usage constitutes most slow downs).
