Holy cow, I wrote a book!
a customer had a question about migrating from Windows 2000
to Windows XP.
(That's right, this customer was still using Windows 2000 in the
Specifically, they noted that in Windows 2000,
they can select multiple languages in the
"Language settings for the system" portion of the Regional Options
and they couldn't find the corresponding control panel setting
in Windows XP.
In Windows 2000,
"Language settings for the system" provides the option to install
support (such as code pages, keyboard layouts, and fonts)
In Windows XP,
the big list of language groups was reduced to three
The Basic category is always installed.
To install the Complex or East Asia categories,
use the "Supplemental language support" section of the
Regional and Language Options control panel.
Someday, that customer might upgrade to Windows Vista,
so I may as well answer the question right now.
In Windows Vista and onward,
things were simplified even more:
All language groups are installed at all times.
The dialog box went away completely since there were no options remaining.
As it turns out, the customer's problem had nothing to do
with language support.
Of course, they didn't come out and describe the problem they were
rather, they reduced the problem into multiple pieces,
and then asked for help on one specific piece.
They tried out a solution based on this new information,
but it didn't solve the problem,
because as it turns out,
the Language settings for the system control panel
was a red herring.
If they had told us what their original problem was,
we could have told them
"But this setting will do nothing to solve your problem.
What you really need is over there."
Tomorrow, we'll look at the customer's actual problem.
(So please don't try to guess or you'll ruin the surprise.
I can't believe I had to write that.)
