Win 7 to win 10 upgrade follow up？
Since then, two things were noticed.
1. Practically every day, several windows open-close for a spit second; not enough time to read anything. One window looks black, like the CMD app.
2. Execution of many programs, in particular opening PhotoShop, slowed down considerably.
The Task manager displays "Antimalware Service" which may cause slowdown. I am not sure what this program is and whether it's redundant.

The intermittent black windows and the slowdown, particularly with Photoshop and other programs, coupled with the "Antimalware Service" in Task Manager, strongly suggest a conflict or resource hogging issue. It's likely related to Windows 11 updates and potentially a poorly integrated or misconfigured security application.
It’s part of Windows Defender Antivirus, responsible for real-time malware scanning. It is built into Windows 10/11 for security.
