This line in a cmd window does what you want:regedit /S C:\Firefox_dde_reg_files\Firefox_dde_remove.reg
* Firefox_dde_remove.reg is the .reg file in the previous post
* C:\Firefox_dde_reg_files\ is just where I put it for a test - you can put it where you want
* You could use the PowerTools Startup Manager to set up regedit /S C:\Firefox_dde_reg_files\Firefox_dde_remove.reg (or whatever you choose to call the location) to run when windows starts
* Or you could set up a regedit shortcut with a Target something like this:
C:\Windows\regedit.exe /S "C:\Firefox_dde_reg_files\Firefox_dde_remove.reg"
