New owners of SSDs often ask if they need to do anything to enable Trim in Windows 7.
Trim is built into Windows 7 and most if not all new SSDs thru firmware updates have this feature automatically enabled.
Before Windows 7 offically lauched a year ago many SSDs needed a wiper.exe program run to perform a Trim action aka garbage collection.
To check if Trim is enabled in Windows 7 on your SSD run
fsutil.exe behavior query DisableDeleteNotify
from an elevated command prompt
Click on the Start Button>All Programs>accessories>Command Prompt
Right Click on Command Prompt and pick Run As Administrator
enter the command
fsutil.exe behavior query DisableDeleteNotify
Enter
It should respond back with:
DisableDeleteNotify=0 if TRIM support is ready and active.
If it's not.. type
fsutil.exe behavior set DisableDeleteNotify 0.
Remember to change to "AHCI" in BIOS before you install the Windows 7 operating system (or change in the index after) on a new SSD otherwise it will bluescreen.
