This command uses the same syntax as the regset command, but places a call to Wow64DisableWow64FsRedirection before launching the 64-bit version of regedit.exe to edit the registry. This allows you to use the native 64-bit registry to set a registry key to the given name and value.

If the key doesn't already exist, this command creates the key with this initial value.

Version Platforms
8.0.584.0 Windows


regset64 <key> <name>=<value>


Set the Level value of the specified registry key to the DWORD 2:

regset64 "[HKCU\Software\Microsoft\Office\9.0\Word\Security]" "Level"=dword:00000002

Set the testString value of the specified registry key to bob.

regset64 "[HKEY_CURRENT_USER\Software\BigFix Inc.]" "testString"="bob"

Clear the data of the specified registry value.

regset64 "[HKEY_CLASSES_ROOT\ShellScrap]" "AlwaysShowExt"=""


This command is Windows-only. It will cause an action script to terminate on a Unix agent.

Notice in these examples that square brackets [] are used to enclose the name of the registry key. Again, this is in keeping with the rules for REGEDIT4 registry files.

When you use the regset64 command, keep in mind that the BigFix client dynamically builds the .reg file that you would have had to create manually to update the registry and then it executes that resulting .reg file for you. One of the rules of the .reg file is that any back slashes \ in the value field need to appear as double slashes \\.

For example, if you were trying to assign the value SourcePath2 of the registry key HKEY_LOCAL_MACHINE\Example to C:\I386, the command that you would define would look like this:

regset64 "[HKEY_LOCAL_MACHINE\Example]" "SourcePath2"="C:\\I386"

Alternatively, you could use the escape relevance inspector:

regset64 "[HKEY_LOCAL_MACHINE\Example]" "SourcePath2"={escape of "c:\I386"}

In situations where you need to issue many regset64 commands, you might consider using the appendfile or createfile until commands to build a properly formatted regedit file, and then run regedit silently:

createfile until end-reg-edit-commands
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion]
"SourcePath2"="{escapes of pathname of windows folder}"
move __createfile setup.reg
wait regedit /s setup.reg

If the specified key doesn't already exist, it will be created by this command.
