můžeš zkusit dokopírovat dll - C:\WINDOWS\system32\kbdgr.dll, C:\WINDOWS\system32\kbdit.dll - a doeditovat registry, jestli to bude stačit:

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout\DosKeybCodes]
"00000407"="gr"
"00000410"="it"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layouts\00000407]
"Layout Text"="Německé"
"Layout Display Name"="@%SystemRoot%\\system32\\input.dll,-5011"
"Layout File"="KBDGR.DLL"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layouts\00000410]
"Layout Text"="Italské"
"Layout Display Name"="@%SystemRoot%\\system32\\input.dll,-5015"
"Layout File"="KBDIT.DLL"
