Administrator Command Prompt
The second option requires no third party software. Users need to start a command prompt with elevated rights. This is done by clicking on the start orb, then All Programs, Accessories, right-clicking on Command Prompt and selecting Run as Administrator.
Now execute the command "fsutil behavior query DisableDeleteNotify" and take a look at the result.
Two results are possible:
DisableDeleteNotify = 0: This indicates that TRIM is enabled and working on the operating system.
DisableDeleteNotify = 1: This means that TRIM is not enabled, and that SSDs will therefor not benefit from it.
If TRIM is not active on the system, which can be the case if the SSD has not been properly recognized, if it is to slow or if drivers have not been properly installed.
TRIM can be enabled with a similar command if it is not enabled in Windows 7. To activate TRIM issue the command fsutil behavior set disablenotify 0.
