First of all: you dont really change the extension, but you can make a file appear exactly like it is another file type. Example: make an .exe file completely look like a .jpg. Having the .jpg extension and icon, but as soon as double-clicked to execute as programmed.
1) Go to "control panel", and then to "date time language and regional options". Click "add other languages"
2) In the "languages" tab, check "install files for complex script and right to left languages (including Thai)"
3) Just below, also check "install files for East Asian languages"
4) Click "details", and then, in the "advanced" tab, check the "extend support of advanced text services to all programs" option
5) Click apply. You have to put your windows dvd in your dvd drive for the new languages to be installed. When the installation is completed, you have to restart your pc.
6) Now, how this works- example:
a)you have the file "sexy_alfdp.exe"
b) right click it and click "rename"
c) as the current name is highlighted click just after "l"(just before "f") and right click just over there.
d) select "insert unicode control character" and then click on "RLO start of right-to-left override"
MAGICALLY your file("sexy_alfdp.exe") now is transformed to "sexy_alexe.pdf"!
Just have in mind that wherever you click "RLO start of right-to-left override", all text after that point, is being reversed (arabic-like), showing last letter to be first, and so on. So you can give to any file, any extension you like!
7) Last step: use the "resource hacker" freeware to change appropriately the icon of your file. If it has a .txt extension it has to look like a .txt file also. Using the freeware is a piece of cake. In terms of shortening this thread and respect to the program's creators I will advise you just to google it!
If you encounter any problems just post it in a reply, I'll be glad to help.
This thread and its writer do not support any misuse of this method towards illegal actions. I strongly disapprove using this method to cheat in any way.

I forgot to mention that the file will retain its new form into any pc, either it has the Asian languages installed or not. With any options applied different to your pc's actually!
