I'm not sure what to think of a guide that "highly recommends" to install "QuickVerse Bible 4.0" AND "PC-Study Bible 2.1" ...?
Also, disabling the task scheduler, NTP and windows file sharing? Disabling Windows updates without suggesting an offline update package? yeah, no, thanks.
To me at least half of this guide sounds like snake oil or cargo cult.
But yeah, some things might be useful for some people. The trick is finding the needle in the haystack
I use Win2003 daily on more powerfull PC (i5-2400, 16GB RAM) and its indeed blazing fast. When cache is warm, everything starts pretty much instantly, so SSD is not really needed. Cache FTW!
