Why doesn't Win7 x64 turn off Prefetch, Superfectch, Readyboost, etc. ?

post #1 of 5
Thread Starter 
According to Microsoft, if Win7 x64 recognizes your OS drive as SSD (mainly when it is not included in the "Select Disks" section of the defragmenter) it will automatically turn off the unnecessary features that Win7 offers namely Superfetch, Prefetch, Readyboost, etc.

Now, my SSD (Corsair Force GT 60GB) is detected by Win7 x64 properly and even has a max 7.9 score under WEI but when I check the registry these features are still turned on with the value of 3. What gives?

Also, am I right in assuming that TRIM is working whether the SSD has an MBR or GPT partition style? I ask this because I decided to take the new GPT partition style for my system (UEFI boot).

The type of filesystem shouldn't matter tbh. You can disable the superfetch functionality via the services.

The TRIM will work as long as you have the AHCI enabled in your BIOS.

Did you re-install from an image when you added your SSD?

For Windows 7 a fresh install is best for SSD, then it does all the things you say and customises itself based on the HW at the time of install.
If you restore from an image from a mechanical disk then you must manually set these after the install.

As far as I understand what Microsoft wrote in their blog is that although these features are still on in the registry, they are actually disabled when your drive is SSD. But I didn't take any chances and disabled them manually in the registry anyway.

No, I did a clean install in my Bnew SSD.

Oh ok. Yeah I guess that's the only way. Now why will Microsoft not show it in the registry if they are disabled by default?
