Prevent rotation of ArcMap marker symbols with data frame rotation

Summary

Marker symbols rotate with the data if the data frame rotation tool is used. Use the ArcMap Advanced Settings Utility to prevent marker symbols from rotating with the data frame.

Procedure

1. Close all ArcGIS applications, and navigate to the following directory:

C:\Program Files (x86)\ArcGIS\Desktop10.8\Utilities

2. Double click the AdvancedArcMapSettings.exe file to launch ArcMap Advanced Settings Utility.
3. Select the Data Frame tab, and uncheck the Rotate marker symbols with dataframe checkbox. This automatically adds the following registry key:

HKEY_CURRENT_USER\Software\ESRI\Desktop10.8\Symbology\Settings\RotateWithTransform to 0 (DWORD value)

Note:
To reinstate marker rotation with data frame rotation, start the utility and check this box. 

4. Click Apply > Close.
