Set binary registry setting through GPO

I've got a REG_BINARY registry key that I'd like to set via GPO. However, the GPO interface to add registry settings simply has a 'Value Data' text field.

I can set the type to REG_BINARY, but what format is the text field expecting the data in so that the key is correctly set?

Should I be converting my data to Hex before entering it here, or should I be doing this in a completely different way?

Solution 1:

I've never personally tested it, but according to this example, it should be in Hex format.

Solution 2:

You could use a bat file to do it and run is as a start up script

Solution 3:

I just faced a similar issue. According to an export of the key, the reg-file consists of the following:

"key-value"=hex:01,\
  00,00,00,30,0c,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00

In order for the Group Policy Manager to read this data, it should be entered as following. Upper case letter and no commas:

01000000300C000000000000000000000000000000000000
