LGTM, Can we append some tests to serialize the new settings? I think we already have a preference setting somewhere so you only need to touch the settings.xml and update the test.

[reddyashish]

Yes, looking into the tests now.

Oops, there is some conflict to address with #13355

@QilongTang Added the BackupInterval and HardwareAcceleration property to the preferences-serialization tests. MaxNumRecentFiles is already added to this test and we have 2 separate tests for the loading of PythonTemplate. We also have a CanUpdatePythonTemplateSettings() test in the CoreTests class that checks: changing the PythonTemplate. So that should cover it.
