If Windows 11 is hanging frequently, it could be due to high CPU usage, insufficient RAM, outdated drivers, or corrupted system files. Start by checking Task Manager (Ctrl + Shift + Esc) for resource-heavy processes. Update Windows, drivers, and firmware. Run SFC /scannow in Command Prompt to fix system errors. Disable unnecessary startup apps and consider increasing virtual memory. If issues persist, a clean boot or system reset may help restore performance.
