Regedit with Group Policy

Currently I have a couple of registry edits which I perform to increase the security of the network. The edits are performed in the following manner:

1) Changes are exported to .reg file
2) .reg file is placed in netlogon share
3) “run command on logon” in group policy is modified to contain “regedit.exe /s file.reg”
4) group policy is applied to all authenticated users

This accomplishes the task but is sloppy in my consideration.

Does anyone know of a way to apply registry edits through GP in a more ‘sanitary’ manner?
