Step 3: Go to downloads, execute the file.
Step 4: 3 New icons on your desktop, double click CryoUtilities and enter the password you entered in step 1.
Step 5: Swap file from 1 to 16(if you have space for 16gb) should only take about 20-30 seconds.
Step 6: Swap value from 100 to 1.
Step 7: Swap disabled trim to enabled, run trim right now.

IF YOU UNINSTALL THE SCRIPT IT WILL NOT REVERT BACK TO YOUR ORIGINAL SETTINGS.
