ok. i've got the framework for an application built; i have all my tweaks in a database and a way to output them properly using a php script. however, a few are specific to my needs, and need to be called out that way. i also went through and looked at MSDN for every single one i could find in a specific group to find the real nice "description" of what it does and such. i want to get the app online though so i can get the general public to voice off whether or not some tweaks are good, adding in others, helping classify misclassified ones, etc. i did a pretty good job, there should be no dupes (or maybe only a couple left) and tried my best to confirm all the data before committing it. question: if i have numeric data like a 1 in REG_SZ, and the field really "wants" a DWORD of 1, is that the same thing? or is datatype truly important. obviously you can't put text in a DWORD, but sometimes numbers (even boolean type stuff) is in a REG_SZ field. just wondering. here's the output of my first run today. i will add on better classifications and groupings and hopefully the ability to solicit feedback about specific ones to either modify their value, change description, or remove unneeded/bad ones. i will also add classifications like "memory" "filesystem" "third party" etc. - and then also a classification for generic setting or personal setting. hopefully then, i can have a script where you can pick and choose the components you want and generate a .reg file off of that. for example, if you don't want some of your special folders on D:\ like i have mine setup in the file below, you'd be able to skip that. http://mikehost.com/~mike/tmp/tweaks.txt please note, i applied this to a vanilla XP box and now i get an error on logon: "cannot load the user's profile" .. "not enough storage is available to process this command" so, one of these is messed up. possibly one of the memory ones, i think i aimed it more towards my athlon 64 machine - and i tried these tweaks on my p4 2.4 machine. any feedback is appreciated - just email me mike@mike2k.com, and i'll have more information up soon on the registry engine.
