>>>Hi everybody,
>>>
>>>I have a little hacker, who somehow made Date/Time/Language options regional settings unavailable. If I click on Date/Time, it opens a Window to adjust time. But if I click on other options, nothing happens. How can I make it work again?

>>>Thanks a lot in advance.

>>Because my Windows at Home is installed w/o any users or other security I can't be in much help, but check:
>>Control Panel->Administrative tools->Computer management->Local Users and Groups and see if there is something suspicious there.

>I re-started my computer and was able to access it, but I don't see a language bar icon in the TaskBar. I can not find, how can I add it. I need it to know which language I'm in.

Control Panel->Regional and Language Options->Languages tab->Details->Language bar->Show Language bar on Desktop
