Windows 11 eats up my drive space

The biggest offenders are the Windows.old folder (40GB) and this mysterious file in C:\Windows folder with a name "D" (10 GB): Are these really necessary? Thanks in advance for any hint!

    To free up space on Windows 11:

    1. Delete Windows.old:
      Use Disk Cleanup:
      • Search for "Disk Cleanup," select your C: drive, and choose Clean up system files.
      • Check Previous Windows installations and delete.
    2. Investigate the "D" File:
      • Check if it's a system or log file. If unnecessary, delete it or move it.
      • Use tools like TreeSize Free to analyze large files safely.

    Backup important data before making changes!
