Whenever I insert a USB/Thumb drive in a USP port, a new WINDOW pops up on my desktop that shows the contents of the the drive just inserted.   Other computers with XP that I use don't do this (and this ONE didn't until I started using a new Sandisk device).   To me this is annoying..   How do I change my system/configuration back so that these windows don't automatically pop up?    Thanks!!Click Start then choose My Computer.
Right click on the drive and select Properties.
Then choose the Autoplay tab near the top.
Now select an action to perform and choose Take no Action.
Then click Apply.

Good luck!JJ 3000 -  Thanks very much for your reply..   I tried this & then ejected the thumb drive - and reinserted it - but unfortunately it did not solve the problem.   (I had actually already tried changing this autoplay setting - but didn't get there same way you described.)   When you go to "Start" then "My Computer" - you have to have the thumb drive inserted, or you only see the hard drive partitions "C:", etc.. and the 2 CD/DVD drives.   I inserted the thumb drive (shows as "J:" in my config.)...  When you right click - and then select the 'autoplay' tab it lists several file TYPES (pictures, video, mixed media, etc..) and I believe you can set a default action (or "take no action") for each of these.  (I selected the latter for all of them.)   In any case when I did this  and then I "stopped" the thumb drive & reinserted it - the same window still automatically pops up on the desktop....    If you or anyone has other suggestions - they're greatly appreciated.      Thanks.Did you re-boot for the changes to take effect ? ?Yes...   I did reboot.   Still did not work.    Does anyone have any more ideas???    ALSO would appreciate if anyone would let me know whether your system always automatically has a window to pop up with its contents whenever you insert a thumb(USB) drive into a USB port??

Thanks,
JR
