===== Windows XP Home vs Pro =====

==== Convert Windows XP Home to HomePro Light ====
 
  * Boot with a Vista installation DVD or [[http://www.nu2.nu/pebuilder/|BartPE]] CD, then run //regedit// from this environment
  * Load hive c:\windows\system32\config\system (from harddisk, file //system// without extension) into HKLM\HomePro
  * Delete content of key HKLM\HomePro\SYSTEM\ControlSet001\Control\ProductOptions\ProductSuite (do not delete key)
  * NOTE: If you need to update the service pack, the ProductSuite needs to be set back to "Personal" for the update
  * Unload hive and reboot into your new HomePro system
  * Run //regedit// from your new HomePro system
  * Edit key HKLM\SYSTEM\CurrentControlSet\Control\Lsa\forceguest from "1" to "0". It is not necessary (and not possible) to disable option //simple file sharing// in folder view.
  * The new functionality for your new HomePro system is now activated
