1) If you go to My Computer > Disk Drive > Properties > Autoplay, you get a choice which program to use to open, data, music, audio,video,etc. If you choose these 'open with' types, the drive will open in a window without a drop down box. I hope this is what you mean.
2) Don't understand. The window should open with the menu of the entire disk/partition, and 'My Documents' is just one folder in a long alphabetical list. There's some default missing if yours is like that, unless you open in Windows Explorer. If you do that try 'explorer /e' or '/s' from the run command.
3)My Documents is set up as a default to place My Music Etc. in a containing folder. There is nothing to stop you deleting everything in it, or renaming, or not using it at all. The 'send to' file is an option which can be regulated to include any folder you can think of, if you want to save data.
There are a few defaults in XP that have increased my workload by several 1000%. I would like to know how to disable them permanently.
First is the drop down box when I put in a CD. Nothing but a Microsoft commercial, freezing the computer and blocking the screen. How do I get rid of that programming.
Second is My Computer. Every time that I go to my stored files I have to click Folders to see some common sense organization. Then, it opens with My Documents expanded. How do I fix them both.
Third is My Documents. Worst time waster ever invented. Anytime I go to my files on the disk I am rerouted to My Documents, and it opens expanded directing me to folders creating by Microsoft and whomever. Same is true when I'm using programs, I am rerouted to My Documents. I would like to totally remove this time wasting program.
