Check the activation of the TRIM command - Windows 10

After a certain time of use, SSDs lose performance because they can not recognize the free blocks of those used. The TRIM command has been implemented in SSDs and operating systems to indicate which blocks of data are not being used and thus to avoid these performance losses. Here is how to verify that the TRIM is active under Windows 10.
1-Right-click the Start button.



2-Click Command Prompt (admin).



3-Enter the following command and press Enter.

fsutil behavior query DisableDeleteNotify

4-If the command returns DisableDeleteNotify = 0, the TRIM command is activated.

5-If it returns DisableDeleteNotify = 1, the command is not enabled. In this case, enter the following command to activate it.

fsutil behavior set DisableDeleteNotify 0
