 This is how I made it happen on Windows Vista. I picked up (click on and
 drag) the disk clean from list on start up and wanted to put it up to the top
 of the menu. The menu closed and here I was holding the disk clean up under
 my pointer the only choice I had was to drop it on my desk top. Then I went
 back to start up and drop it where I wanted it at the top of start menu. Then
 the short cut that was on my desk top I delete it. When going back to disk
 cleanup after a disk clean up was preformed. I no longer can do a disk
 cleanup from the one that is top of my menu. I can find it by typing in tools
 and using it from the performance information tools only (typing in disk
 clean up I get nothing now in the search from start). I delete the none
 working one from my menu now. I like to know how I can put disk clean up  
 back on my start menu????? I know how from there  to put it on the top of
 menu without using pick up and drag now ......lol big problem that caused it
 to start with.

Next time it does something like that, hit Escape before releasing the
mouse button.  That will cancel the drag operation.

Right-click start button, 'explore' (or 'open', but I prefer to have
the folder tree so I have a better visual indication of where I'm
doing something).

Open 'Programs' (or any subfolder thereof), right-click -> New ->
Shortcut, enter 'cleanmgr.exe' for the location.

Entering the full path is not necessary, but it's in windows\system32
in case you wanted to know.

Click Next -> in the next step you can enter any description you like,
but keeping the original name (Disk Cleanup) may not be a bad idea ;)
