Powershell reg save vs. reg query on remote workstations

Hi guys,

I need to export registry keys from a remote computer for import into other remote machines (copy) using PowerShell V3.0.

When I use REG QUERY to view the registry keys thus:

    reg query \\[computername]\HKLM\[subkey] /s | Out-File -append .\export.log

all subkeys are recursively output to export.log as expected.

However, when using REG SAVE to actually save a copy of the registry (in order to use REG RESTORE to import keys into target computers):

    reg save \\[computername]\HKLM\[subkey] .\export.hiv

I am encountering the following error: "ERROR: The system was unable to find the specified registry key or value."

What's going on? Why can the REG QUERY find the specified keys/subkeys but not the REG SAVE?

Watch Question

Looking at reg save /? vs reg query /? it looks as though reg save cannot be run against a remote machine (and nor can reg restore).

You could try using PowerShell Remoting or psexec.exe to run the command remotely.


Yep, thanks. will user PSEXEC.

Even though this has been handled there are much easier ways to accomplish this if you have remoting enabled.

You can do a reg export instead to create a straight .reg file.
From there, you can use powershell to copy the reg file to the fixed location, and use invoke-command -computername <machinename> -scriptblock { reg.exe /s \\<server>\path\<file.reg> }
