If you have an SSD (a fast type of storage drive) in your Windows 11 PC, you might want to know about TRIM. This guide will help you check if TRIM is on, and show you how to turn it on or off easily.

What is TRIM and Why Does It Matter?

When you delete files on an SSD, TRIM tells the drive which parts are no longer needed. This helps the SSD clean up and get ready for new data faster.

Why is this good? SSDs need to erase old data before writing new data, so TRIM helps keep your drive fast and healthy by doing this cleanup ahead of time.

When Should You Use TRIM?

• Keep it ON: For everyday use, it’s best to keep TRIM enabled to keep your SSD working well and lasting longer.
• Turn it OFF temporarily: If you accidentally deleted files and want to try recovering them, turning off TRIM temporarily might help because TRIM can erase deleted data quickly.

How to Check If TRIM is Enabled on Your SSD

1. Press Windows + X and choose Windows Terminal or Command Prompt.
2. Type or copy-paste this command and press Enter:
   

   fsutil behavior query disabledeletenotify

3. Look at the result:
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   

   Output	What it Means
   DisableDeleteNotify = 0	TRIM is ON (good!)
   DisableDeleteNotify = 1	TRIM is OFF

1. Right-click the Start button and select Windows Terminal (Admin).
