How do I customize keyboard shortcuts in Windows XP?

I don't know where they are defined or how to change them (I don't you really can change most, if you can at all), but here is a http://support.microsoft.com/kb/301583 of them.

Try http://sourceforge.net/projects/hotkeybind/files/. You find a short description http://www.techmalaya.com/2008/05/23/windows-shortcut-keys-hotkeybind/.

If the conflicts are ones that start programs, then they are defined as shortcuts in .lnk properties - however there are no defaults so you -- or someone -- has to have set them. You can go into explorer and do a properties on each .lnk file -- or if you have some programming skills you can do as I did -- see bottom of this answer. I found this was implemented "horribly" in XP -- apparently the start menu "tree" of .lnk files is NOT scanned and loaded into a little table. So if you haven't used a shortcut in a while it will have to look thru and open every .lnk file until it finds the right one. Instead I prefer Macro Express, and while fee-based, is definitely worthwhile. I wrote my own "find all shortcuts" program, which is in KEDIT and thus not "portable" (for it relies on non-free Kedit to run). But the LOGIC might help someone else do a search: The logic is this: read the 65th and 66th byte of every .lnk file in the documents and settings\ files. The 65th byte is the "key" with a decimal 220 meaning "\"; and the 66th byte is a bit of "what other keys go with it": '00000110' = "Ctrl+ Alt " '00000101' = "Shift+Alt " '00000011' = "Shift+Ctrl" '00000100' = "Alt " '00000010' = "Ctrl " '00000001' = "Shift " P.S. I probably could rewrite this in AUTO-IT to be portable if there is a need and no substitute.
