Pull Request Overview
This PR addresses a bug in the Windows DNS configuration where stale registry entries were not properly cleaned up when the number of match domains decreased between configuration updates. The fix ensures that old NRPT (Name Resolution Policy Table) entries are removed before applying new DNS configurations.
Key Changes:
- Registry cleanup now occurs before applying new DNS match policies instead of only when match domains are empty
- Added comprehensive test coverage to verify cleanup behavior when domain count decreases
