Windows 7 Trim Tool
Windows 7 Trim Tool
The disk defragmenter isn't recommended for SSDs, especially in Windows 7. For SSDs, use tools designed for them to avoid damaging performance.
Keep your SSD untouched, Windows handles everything adequately.
On Windows 7, the Disk Defragmenter won’t run TRIM when you press the defrag button—it actually does the opposite. Microsoft states that during scheduled OS updates it will recognize an SSD and trigger TRIM. The tool was renamed to Optimize Drive in Windows 8 and 10; now it identifies SSDs and, when you choose one, click "Optimize" (no longer a Defragment button), it performs TRIM automatically.
