Windows 7 Services and OCer Level Tweaks
If you are performing tweaks at this level then you should already know how to get to such places as Services and the Registry. To keep the pretenders at bay, we will not go into great detail about how to get to these areas.
Platter drives need to be defragmented around once a week, but solid state drives keep files organized in house. Windows 7 should automatically disable this feature when it detected your SSD, but you should verify that the service is not running. You can find this setting in the Services area.
Disable System Restore
If you are not using your machine for system critical applications and can afford to "lose it all" in the blink of an eye, you can disable System Restore to gain both performance and drive capacity.
Superfetch is designed to cache files used often, but with the low access times of SSDs this option can be disabled. You may find that slower SSDs will actually benefit with this option enabled after a few weeks of use. Feel free to enable this feature if you find your system starting to run slower. You can find this setting in the Services area.
Prefetch loads pieces of program files into RAM and is one of the new tricks Microsoft has used to make Windows 7 seem faster to users. By disabling this feature you will free up system RAM and allow your SSD to run like it was meant to.
Getting to Prefetch requires experience with Regedit.exe. Once you are in the register follow this path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
Find Enable Prefetcher, right click on the right pane then choose modify. Change the value from 3 to 0, hit OK. Once completed and you have backed out of the registry, you must restart your PC for the changes to take effect.
