Change HKCU registry entries via Logon Script in Group Policy.

• Create Registry.reg file with required registry changes. E.g. following will disable “Download Windows Search” prompt in MS Outlook 2010:
  Windows Registry Editor Version 5.00
  [HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Search]
  “DisableDownloadSearchPrompt”=dword:00000001
  

• Create Registry.bat file with text:
  %systemroot%\regedit /s Registry.reg

• Open Group Policy object, go to User Configuration > Windows Settings > Scripts > Logon
• Click on Show Files (this opens a folder in \\domain-name\SysVol\domain-name\Policies\… ) and copy both files you created to that folder.
  
• Click on Add and select Registry.bat
• Deploy Group Policy object where required.
