Optimizing Windows 7 For The Ssd And Trim

Now that you have gotten everything done as far as firmware, and image restored and have a working Windows 7, we can do some things to make Windows 7 a bit 'friendlier' to your SSD and make things faster to boot.

FWIW, Microsoft did a great job in pre-optimizing Windows 7 for SSD use. Except for installation, over 95% of Windows 7 operations are READS, perfect for your SSD. You COULD just use it as is and things would be fantastic. BUT, there are some things to verify first.....

1: Verify that TRIM is enabled as in the prior messages.
2: Make sure your AHCI controller is using a TRIM compliant driver as in the prior messages.
3: Make sure the defrag program is disabled for the SSD... Admin tools/Services set Disk Defragmenter to disabled. I use auslogics disk defrag (free) for my other drives manually. U almost never have to defrag an SSD. It can lower its life expectancy.
4: Page File. There has been much debate about this. The idea that no one needs a page file is a bunch of crap. I have tried it both ways, moitoring writes and reads, and YES, it IS used even with 8 Gigs of RAM. I left mine at 2 Gigs, but it is just fine at 1 Gig. Writes to the page file are sequential now. Page file is also read at boot time to speed things. Keep it on your SSD where it belongs.
5: Superfetch/prefetch/bootfetch: Windows 7 does not always turn it all off as it should. The purpose of these things are to pre-load the programs you load from slow hard drive to fast memory (cache) in case you want to run them. With your SSD, there is no need. We will disable them and free up some memory and resources and stop a LOT of writes to the SSD.
To disable Superfetch, etc: Admin tools/Services. Select superfetch and set to disabled.
Run regedit and change the following values: HKLM/System/CurrentControlset/Control/Session Manager/Memory Management/Prefetch Parameters and change the key valus of Enableboottrace, enableprefetcher, enablesuperfetch all to 0 and exit regedit.

This will disable MOST of the superfetch/prefetch stuff... The boot prefetch will get disabled in the next part along with some un-necessary logging that is done (and writes a lot).
