Hi, wrecko
Welcome to Microsoft Community.
We understand that you are experiencing system slowness while using Windows 11. From your description, this could be caused by corrupted system components, third-party software interference, disk corruption, etc. We suggest you try the following options:I.Perform a clean bootThe method is as follows1. Tap Windows+R and type msconfig2. Open System Configuration and select General tab - Selective Startup.3. Remove the checkmark of Load startup items.4. Go to the Services tab - click Hide all microsoft services in the lower left corner, and then click Disable all.5. Click OK and restart your computer. (Be sure to select Hide all Microsoft services first and then click Disable all, otherwise it may cause unforeseen problems such as not being able to access the system.)See if the problem recurs.*Disclaimer: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.**These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by step so that it will help you get back on track.*II. Try to repair the system1. Search for CMD, find the command prompt, and choose to run in administrator mode.2. Enter the following commands one by one, and be sure to execute the next command after the previous one is completed.DISM /Online /Cleanup-Image /ScanHealthDISM /Online /Cleanup-Image /CheckHealthDISM /Online /Cleanup-Image /RestoreHealthSFC /ScannowIII. Try to use chkdsk to detect the disk.1. Click Win+X to open “Command Prompt (Administrator)”.2. In the Command Prompt window, type chkdsk <disk letter>: /fFor example, to check and repair partition D:chkdsk D: /fEnter to start the chkdsk disk checker to scan partition D. Checking other partitions is similar.Note: Please check your disk drive other than C drive first, checking C drive requires a reboot to execute, type Y and then press enter.*Disclaimer: Running chkdsk can check the file system and file system metadata of a volume for logical and physical errors. To avoid any trouble for you, do not cancel or interrupt chkdsk, and back up important data.*More information please refer to this chkdsk | Microsoft Learn.If the problem still exists after you execute the above solutions, you can provide pictures or videos about the problem, we need this information to understand your specific situation more intuitively and give further solutions.
