Windows includes built-in tools to safely maintain and improve the performance of both SSDs and HDDs even while you're using your PC. Below are best practices, what\u2019s automatically handled, what you may want to do manually, and important warnings.\n\n---\n\n## What Windows 11 Automatically Does\n\n1. **Scheduled Optimization**  \n   Windows regularly runs optimization tasks on all local drives:\n\n   - For HDDs (mechanical hard drives): it performs *defragmentation* \u2014 reorganizing file fragments so the drive reads them more efficiently.  \n   - For SSDs and NVMe drives: it performs *TRIM* operations, telling the drive which blocks no longer contain valid data so the storage controller can clean them up later. ([support.microsoft.com](https://support.microsoft.com/en-us/windows/defragment-optimize-your-data-drives-in-windows-54d4fed1-c96e-46db-b843-8c6b34bd27a4?utm_source=openai))\n\n   By default, optimization runs weekly. You can view or change this schedule in the \u201cOptimize Drives\u201d tool. ([support.microsoft.com](https://support.microsoft.com/en-us/windows/defragment-optimize-your-data-drives-in-windows-54d4fed1-c96e-46db-b843-8c6b34bd27a4?utm_source=openai))\n\n2. **Drive Identification**  \n   Windows automatically detects whether a drive is SSD or HDD and chooses the appropriate optimization action. ([serverman.co.uk](https://www.serverman.co.uk/software/microsoft/windows-11/win11-optimise-drives/?utm_source=openai))\n\n---\n\n## What You Can Do Manually When Windows Is Running\n\nThese operations are safe to perform while Windows is active:\n\n- **Optimize Drives (built-in GUI tool)**  \n  Go to *Start \u2192 Defragment and Optimize Drives*. Select C:, then \u201cAnalyze\u201d (for HDDs) or simply \u201cOptimize\u201d to force a defrag (if needed on HDD) or retrim (on SSD). ([support.microsoft.com](https://support.microsoft.com/en-us/windows/defragment-optimize-your-data-drives-in-windows-54d4fed1-c96e-46db-b843-8c6b34bd27a4?utm_source=openai))\n\n- **Via Command Prompt or PowerShell**  \n  \u2003 \u2003 - `defrag C:` or `defrag C: /O` \u2014 performs the right action for the drive type (defrag for HDD; TRIM + minimal file reorganization for SSD) ([serverman.co.uk](https://www.serverman.co.uk/software/microsoft/windows-11/win11-optimise-drives/?utm_source=openai))  \n  \u2003 \u2003 - `defrag C: /L` \u2014 force TRIM (or retrim) on an SSD ([serverman.co.uk](https://www.serverman.co.uk/software/microsoft/windows-11/win11-optimise-drives/?utm_source=openai))  \n  \u2003 \u2003 - `Optimize-Volume -DriveLetter C -Verbose` in PowerShell, as admin, also works. ([elevenforum.com](https://www.elevenforum.com/t/optimize-and-defragment-drives-in-windows-11.3212/?utm_source=openai))\n\n- **Freeing Up Space**  \n  Whether you have an SSD or HDD, sufficient free space is important \u2014 especially for defragmentation on HDDs, but also for SSDs to allow good garbage collection and wear levelling. Removing unneeded files, clearing temporary files, etc., helps. ([learn.microsoft.com](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/defrag?utm_source=openai))\n\n---\n\n## Important Considerations & Limitations\n\n- **HDD vs. SSD**  \n  You *should defragment* an HDD when fragmentation rises (usually over ~10%), but for SSDs, traditional defragging is generally unnecessary and can increase wear. For SSDs, TRIM is what matters. Windows makes that distinction automatically when using the built-in tools. ([makeuseof.com](https://www.makeuseof.com/defrag-hard-disk-drive-windows-11/?utm_source=openai))\n\n- **While Operating System Is Running**  \n  Because Windows is using system files, swap/page files, etc., it can\u2019t defragment parts that are locked in use \u2014 for instance, certain system files or OS metadata. That\u2019s normal. Windows skips those or does boot-time optimizations if needed. ([learn.microsoft.com](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/defrag?utm_source=openai))\n\n- **Drive Health & Wear (for SSDs)**  \n  Avoid filling an SSD to near capacity. Also, minimizing unnecessary writes helps prolong SSD lifespan. So don\u2019t over-use write-heavy tools, and make sure TRIM is active. ([windowscentral.com](https://www.windowscentral.com/microsoft/windows-11/10-essential-maintenance-tips-to-keep-your-windows-11-pc-running-longer?utm_source=openai))\n\n- **File System Support**  \n  Drives must use NTFS, FAT, exFAT, or ReFS for the built-in optimization tools to work properly. External, networked drives or unusual file systems may not support all features. ([support.microsoft.com](https://support.microsoft.com/en-us/windows/defragment-optimize-your-data-drives-in-windows-54d4fed1-c96e-46db-b843-8c6b34bd27a4?utm_source=openai))\n\n- **Administrator Rights**  \n  To manually run defrag, TRIM, or optimization commands, you\u2019ll need administrator privileges. ([learn.microsoft.com](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/defrag?utm_source=openai))\n\n---\n\nIf you want, I can walk you through the specific steps for your configuration (SSD or HDD) so you can trim or optimize your C: drive right now. Do you want to do that?"
