+- Download the latest available DISA-provided GPO baseline zip file: https://public.cyber.mil/stigs/gpo/
+
+- Unzip the GPO baseline file on your computer
+
+- Open the unzipped folder and browse to the desired baseline to update
+
+- To identify the STIG GPO baseline associated with each GUID, you have to navigate into the GUID directories and open gpreport.xml. The <name> tag near the top in the xml will identify the STIG baseline provided
+
+- Depending on the baseline, the `Machine` and `User` policies maybe under the same GUID or separate GUIDs.  In either case, the following steps still applies
+
+  - Open `{GUID}\DomainSysvol\GPO\Machine` and copy `registry.pol` to the `stig/<baseline>` folder, renaming it to `machine_registry.pol`.  Skip this step if `registry.pol` is missing or contains no policies (e.g. File size is very small)
+
+  - Check for `audit.csv` and `GptTmpl.inf` files under `{GUID}\DomainSysvol\GPO\Machine\microsoft\windows nt\` and copy them to `stig/<baseline>`
+
+  - Open `{GUID}\DomainSysvol\GPO\User` and copy `registry.pol` to the `stig/<baseline>` folder, renaming it to `user_registry.pol`.  Again, skip if `registry.pol` is missing or contains no policies (e.g. File size is very small)
