How to enable / disable TRIM support for SSDs in Windows 10

This guide will show you how to check the current status of TRIM support for SSDs and to enable or disable TRIM support for NTFS and ReFS file systems in Windows 10.

The TRIM command is essential to maintain the performance of SSDs at an optimal level throughout its life cycle. TRIM proactively removes invalid data from SSD memory cells to ensure write operations take place at maximum speed.

Because the memory block must be erased before it can be reprogrammed, TRIM improves performance by actively deleting pages that contain invalid data, allowing the SSD to write new data without having to do so. Delete command takes time.

TRIM support for SSDs is enabled by default and is recommended to always be enabled. If turned off, there is a risk of SSD fragmentation instead of optimization.
