I don't recommend Tweak-SSD. Instead I would use the software provided by the drive manufacturer. Windows 7 and later automatically recognizes and configures the OS for an SSD, for XP and Vista I previously posted my recommendations here: viewtopic.php?p=13817#p13817
For XP and Vista you will especially want the utility from the drive manufacturer (e.g. Intel, Samsung) to periodically run the TRIM command. These utilities will normally also check and/or optimize other OS settings. Scott.
