Perform a clean boot of your system

A clean boot, also known as a clean startup, is a troubleshooting technique used in Windows operating systems to diagnose and isolate software conflicts or issues. By performing a clean boot, you start your computer with a minimal set of drivers and startup programs, allowing you to identify and resolve problems that may be caused by conflicting software or services.
