How can I change registry values from the command line?

A. The Windows 2000 and Windows NT Server resource kits include the regfind utility, which you can use to find (and change) values in a registry location. For example, you can enter the following command:

C:\> regfind -p HKEY_CURRENT_USER\Control Panel\Desktop
"old value" -r "new value"

where "old value" is the old wallpaper name and "new value" is the new wallpaper name. You can add the -m switch and use regfind to modify remote machines:

C:\> regfind -m \\\[computer name\]-p HKEY_CURRENT_USER\Control
Panel\Desktop "old value" -r "new value"
