  • May offer a cleaner scan compared to /scannow.


2. Disk Cleanup

  • Command: cleanmgr
  • Purpose: Frees up disk space by removing unnecessary files such as temporary files, system cache, and old Windows updates.
  • How to Use:
    1. Open Disk Cleanup from the Start Menu.
    2. Select the drive you want to clean (usually C:).
    3. Choose the file categories to delete and click OK.

3. Check Disk (chkdsk)

    1. Open Command Prompt as an administrator.
    2. Type chkdsk /f or chkdsk /r and press Enter.
    3. Restart your computer if prompted.
  • When to Use: If you suspect file system corruption, bad sectors, or experience slow performance.


4. Temp Folder

  • Location: C:\Windows\Temp or %TEMP%

    • In Chrome: Go to Settings > Privacy and Security > Clear Browsing Data.
    • In Edge: Go to Settings > Privacy, Search, and Services > Clear Browsing Data.
  • When to Use: If web pages are loading incorrectly or to protect privacy.


6. Disk Defragment

  • Command: dfrgui or defrag
  • Purpose: Optimizes the arrangement of files on the disk for faster access (for HDDs, not necessary for SSDs).
  • How to Use:
    1. Open Defragment and Optimize Drives from the Start Menu.
    2. Select the drive to defragment and click Optimize.
  • When to Use: Periodically for HDDs to maintain performance (not applicable to SSDs).
  • Note: If more than 15% free space in the drive, use the GUI interface, else use the command-line interface


Best Practices

  • Use these tools together periodically to maintain your system’s health and performance.
  • Always back up important data before running tools like chkdsk or Disk Cleanup to avoid accidental data loss.
