Thank YouVista does not support TRIM, Microsoft was too lazy to add a few extra lines of code. But... "Yes, we can. Yes, we did." ©
After installing Vista on the SSD, you need to install "O&O Defrag" pro-version 15 or higher (or buy, or download online cracked), then in the "settings" (tab "free spase optimizations") to set the schedule for SSD optimize with TRIM (I recommend every 6 hours). That's all, the program will run the TRIM command on a schedule in the background.
