Windows Cannot Set a Default Printer

Windows Cannot Set a Default Printer

Release

Windows 2000,Windows XP, Windows Vista, Windows 7

Problem

When we try to set a default printer, after changing the default printer in the printer’s control panel it reverts back to the previous default printer.

Solution

To fix this problem we need to change device value in registry.

    Open registry editor and locate the path

“HKEY_CURRENT_USER/ SOFTWARE/ MICROSOFT/ WINDOWS NT/ CURRENT VERSION/ WINDOWS”

  On the right pane Change entry for Device that has winspool,Ne00; delete whatever printer there is in the entry and just leave winspool,Ne00.Close the registry editor and restart the windows explorer.
