Hi, I'm Bernard, a fellow Windows user. I'm happy to help!
I understand the issue you have. There is nothing to worry about. I am here to assist. Does the pop-up occur when you start the PC or intermittently while using? Do you remember any app you installed lately that may cause the issue?
While waiting, let us run Autorun, wherein we will remove unnecessary files that are not in use and are corrupted.
Go to this link: https://learn.microsoft.com/en-us/sysinternals/downloads/autoruns
Click "Download Autoruns and Autorunsc"
Then open and run Autoruns
Delete all highlighted with Pink and Yellow color (If you cannot delete some of those, it is okay to skip)
Method 2. Do a clean boot:
A “clean boot” starts Windows with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your game or program.
- In the search box on the taskbar, type msconfig and select System Configuration from the results.
- On the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all.
- On the Startup tab of System Configuration, select Open Task Manager.
- Under Startup in Task Manager, for each startup item, select the item and then select Disable.
- Close Task Manager.
- On the Startup tab of System Configuration, select OK. When you restart the computer, it's in a clean boot environment.
