Windows 8.1 And SSDs
Prefetch
As I had found earlier (Windows 8.1 RTM And SSDs) Windows 8.1 IS NOT optimizing itself for SSDs. This is a direct result of pulling WEI / Winsat assessment.
– All 4 machines SSDs were correctly identified as such (check defrag).
– All prefetch settings were:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
“EnableSuperfetch”=dword:00000003
“EnablePrefetcher”=dword:00000003
– ran winsat formal, rebooted. Prefetch settings changed to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
“EnablePrefetcher”=dword:00000003
The EnableSuperfetch value was removed.

ReadyBoot
ReadyBoot is also disabled by running winsat formal. Key:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WMI\Autologger\ReadyBoot]
“Start”=dword:00000000
Start value changed from 1 to 0

I recommend you run winsat formal.
Press the Windows + R keys and type winsat formal .
Now check the folder C:\Windows\Performance\WinSAT\DataStore for the scores.
Go to the above key ( press the Windows + R keys type regedit) and remove the EnableSuperfetch value.
