I've got a T5630w and I didn't manage to activate The Recycle Bin to work properly.
In c:\Recycler\ folder I found 2 folders (1 for Administrator & 1 for User), so I've been able to restore the option to use the Recycle Bin but I just can make a shortcut on the Desktop (it's work fine but it's not the true Recycle Bin).
Than, I try to edit the register file ...
and I try pgedit.msc without any result.
Does HP disable the Recycle Bin by an other mysterious way ?
