How to ensure TRIM is enabled on Windows 10 to keep an SSD at top performance

What is Trim?

TRIM is an essential feature for an SSD to keep it on top performance and helps the drive to last much longer. TRIM is an ATA command set that was originally designed for the purpose of keeping a Solid State Drive at its optimal performance throughout its lifespan.

How to check TRIM is enabled in your Windows 10 PC

Making sure that TRIM is enabled on Windows 10, you only need to use a command using the Command Prompt with administrator privileges.

Use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (Admin).

Type the following command and press Enter:

fsutil behavior query DisableDeleteNotify

Tips:

If after executing the fsutil command with the DisableDeleteNotify you get a result of zero (0), then it means that TRIM is enabled, and no further action is required. However, if after running the command you see a result of one (1), then it means that TRIM is disabled.

How to enable TRIM on your Windows 10 PC

When TRIM isn’t enabled on Windows 10, you need to do the following:

Use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (Admin).

Type the following command and press Enter:

fsutil behavior set DisableDeleteNotify 0
How to enable TRIM on your Windows 10 PC

After running the command, you will notice the same DisableDeleteNotify = 0, which indicates that the feature is enabled.

By the way, if the TRIM of this SSD is enabled, the deleted or lost files on this SSD will be damaged and you cannot recover these files using data recovery software.

How to disable TRIM

If at any time for any reason you need to disable TRIM, you need to do the following:

Use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (Admin).

Type the following command and press Enter:

fsutil behavior set DisableDeleteNotify 1
How to disable TRIM

For TRIM to work, both the operating system and the Solid State Drive must support the feature, and it must be enabled in the operating system.

While we’re focusing the guide for Windows 10, you can use the same commands on Windows 7 and Windows 8.x.
