System maintenance is crucial for ensuring the smooth operation and longevity of your Windows environment. Regular maintenance can help prevent issues, enhance performance, and secure your system from vulnerabilities. This article will guide you through essential maintenance tasks using built-in Windows tools and commands.

1. Disk Cleanup: This tool helps free up space on your hard drive by removing unnecessary files. You can access it via the GUI or run it from the command line.

   Example:

   • Open Command Prompt as an administrator.
   • Run the following command to start Disk Cleanup for drive C:

     cleanmgr /sagerun:1

2. Check Disk Utility (CHKDSK): This tool scans your hard drive for errors and attempts to fix them.

   Example:

   • Open Command Prompt as an administrator.
   • Run the command:

     chkdsk C: /f /r

   • The /f parameter fixes errors on the disk, while /r locates bad sectors and recovers readable information.

3. Defragment and Optimize Drives: Fragmentation makes your hard disk do extra work that can slow down your computer. The Optimize Drives tool rearranges fragmented data so your disks and drives can work more efficiently.

   Example:

   • Open Command Prompt as an administrator.
   • Run the command:

     defrag C: /O

   • The /O parameter performs optimization and consolidation on the specified volume.

4. System File Checker (SFC): This utility scans for and restores corrupt Windows system files.

   Example:

   • Open Command Prompt as an administrator.
   • Run the command:

     sfc /scannow

5. Windows Update: Keeping your system updated is vital for security and performance improvements.

   Example:

   • You can check for updates manually by going to Settings > Update & Security > Windows Update.
   • Alternatively, run the following command in PowerShell to check for updates:

     Install-Module PSWindowsUpdate
     Get-WindowsUpdate
     Install-WindowsUpdate

6. Task Scheduler: Automate maintenance tasks using Task Scheduler to ensure they are performed regularly without manual intervention.

   Example:

   • Open Task Scheduler from the Start menu.
   • Create a new task to run a maintenance script at regular intervals.
