Software for HP 2840 printer won't install on XP without USB drivers (eg. virtual PC)

Copy the installation files from CD to hard disk. Find the file "HPZchk01.exe". Replace it with a "do nothing" exe file. Windows Notepad.exe will also do as a last resort.

Hack to convert Windows XP Home to Windows XP Professional

  • Open Registry Editor (regedit).
  • Navigate to HKEY_LOCAL_MACHINE/SYSTEM/ControlSet00X/Control/ProductOptions, where X is the highest number.
