Drive optimization


# Analyze and optimize a Windows drive.




Updated 
October 5, 2026




Open Defragment and Optimize Drives, select the local drive, and choose Optimize. For an elevated command prompt, use defrag C: /O /U /V so Windows applies the operation appropriate to the drive’s media type.




## Use the graphical tool




1. Search Windows for **Defragment and Optimize Drives**.
2. Select the correct volume and choose Analyze when available.
3. Choose Optimize and allow Windows to apply the operation appropriate to the media.




## Use an elevated command prompt


` defrag C: /A /U /Vdefrag C: /O /U /V `


` /A ` analyzes the volume. ` /O ` performs the proper optimization for each media type, while ` /U ` shows progress and ` /V ` provides verbose statistics. Network drives are not supported.




## With Screensie




Screensie does not label this as a one-click repair. An authorized technician can use Command Center’s confirmed CMD console to run the standard ` defrag ` command and receive bounded output without taking over the screen. Use PCInfo first to confirm the drive and free space.

## Common questions




**How do I optimize a Windows drive?**




Open Defragment and Optimize Drives, select the correct local volume, and choose Optimize. From an elevated command prompt, defrag C: /O /U /V lets Windows choose the operation appropriate to that media type.




**Can I analyze a drive before changing it?**




Yes. Run defrag C: /A /U /V to analyze the selected local volume and review the report. Replace C: only after confirming the intended drive; network drives are not supported.




## Use the right tool remotely




Inspect storage in PCInfo, then run only the confirmed operation you intend.
