I've had similar issues with Windows 10 Pro version 21H2. To improve your system performance and boot time, here are a few steps that worked for me:
- Run System File Checker: Open Command Prompt as an administrator and type
sfc /scannow
. This will check for corrupted files and repair them.
- Disable Startup Programs: Go to Task Manager > Startup tab, and disable programs that you don't need at startup.
- Check for Malware: Sometimes malware can slow down your system. Run a full system scan with your antivirus software.
- Install Updates: Make sure all the latest Windows updates are installed, as they often include performance improvements and bug fixes.
Also, if these steps don't help, consider creating a modern user profile or even resetting Windows if nothing else resolves the issue.
