Introducing my friend Reg

Registry Tool | Admin Arsenal

A command-line tool that I have found very useful lately is reg.exe, the command-line registry editor. It is particularly useful to make changes to computers remotely using Admin Arsenal’s batch file deployment or remote command.

It has a number of different commands (see them by running reg /?) but the ones I use most are ADD and DELETE. It is available on all current versions of Windows so you don’t need to worry about deploying it. It’s particularly helpful to make a configuration change to a number of computers at a time without using a GPO and waiting for it to be applied. Recently I needed to enable unsolicited Remote Assist on a bunch of computers and reg.exe came to the rescue.

I created the following batch file:

reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v fAllowUnsolicited /t REG_DWORD /d 1 /f
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v fAllowUnsolicitedFullControl /t REG_DWORD /d 1 /f
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server" /v AllowTSConnections /t REG_DWORD /d 1 /f
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0 /f
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fAllowToGetHelp /t REG_DWORD /d 1 /f

Then using Admin Arsenal’s software deployment, I pushed the batch file out to the computers and voilà Remote Assist was enabled.

Next time you need to make registry changes on more than one computer, keep this option in mind.
