Configuration of Polish characters in Windows 7 and 8 is strightforward but apparently not widely known - some people try to use symbols instead.

Control Panel>Clock, Language, and Region>Language>Add a Language>Polish (polski)

Make sure that keyboard layout is Polish Programmers. Use ALT+SHIFT to change languages and right ALT+a,e,c,s,z,n,x.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Lanmanworkstation\Parameters

DirectoryCacheLifetime (Dword file, set to zero)

Here is how to do that, pretty unexpected procedure which is a result of an OS developer weakness and somebody's creativity:

• net stop spooler
• go to C:\Windows\System32\spool\PRINTERS
• delete everything
• net start spooler

• bcdedit /set nointegritychecks ON
• shutdown /r /t 0
• install your drivers
• and then when you are done with the installation: bcdedit /set nointegritychecks OFF
• shutdown /r /t 0
