How to make sure TRIM is running on Windows 7 PC after installing new SSD?

How can I make sure TRIM is working after I install a new SSD on a Windows 7 PC that came with a HDD (will be reinstalling Windows 7)?

Verify That TRIM Is Enabled In Windows 7

"Windows users need to make sure that TRIM is working properly, especially if they notice that the performance of the Solid State Drive seems to drop significantly over time.

We would like to introduce two options to find out if TRIM is enabled in the operating system."

1. Open a command prompt window. Run as administrator.

2. Enter this command: fsutil behavior query DisableDeleteNotify

3. If you get DisableDeleteNotify=1, TRIM is not working. If you get DisableDeleteNotify=0, TRIM is running.
