Hi all, I wonder if anyone can help me with this simple batch file. I want to load this batch file at t-12 during an unattended install and customise the install for a specific user & organisation. This will mean that I can use this disk on multiple install, if necessary. the batch file includes @echo off SET /P PCOWNER=Please Registered Owners name: REG ADD HKLM\SOFTWARE\Microsoft\windowsNT\currentversion /v RegisteredOwner /t REG_SZ /d %PCOWNER%/f echo %PCOWNER% PAUSE Eachtime I test this batch file, it says successfully installed but the system properties show the original registered Owner, even after re-booting. I am sure I am making an obvious and simple mistake................please help
