Another thing I have found to be useful is to
Open Regedit
Locate key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\MemoryManagement\PrefetchParameters
Change EnablePrefetcher from 3 to 5 and reboot twice.
This key tells the operating system to remember the programs you have launched and allows them to load quicker. After time this list starts to build up even with programs you used 1 time.
This will purge that list
