What is the manual method of modifying the Default Domain Policy GPO to execute a logon script without using automated tools?

First, upload the script to `\\test.com\sysvol\test.com\Policies\{GPO_GUID}\USER\Scripts\Logon`. Then create a hidden file `scripts.ini` in the same `Scripts` folder with content like `[Logon] 0CmdLine=test1.bat 0Parameters=`. Next, increment the `Version` value in `GPT.INI` by 65536 (e.g., from 3 to 65539). Finally, update the Active Directory database (e.g., using SharpGPOAbuse or by modifying the backup XML). This forces clients to process the new script on their next policy refresh.
