Amazing indeed, but whenever someone says the whole team of Microsoft, including Bill gates could not explain it, it sounds really fishy. So I look up over the internet and found very interesting explanation

Magic #1
Some device names are reserved and forbidden for folder names that includes CON, PRN, AUX, NUL, COM1 upto COM9, LPT1 upto LPT9 etc. [I believe someone wrote about this previously in the group]. So you can't create folder with those names on usual windows environment. But interestingly you can still do this by using MS prompt

md.c:con
Now go and see in your C drive.
Want to delete it? Do it by using command
rd.c:con
Magic #2
Try with UNICODE (from drop-down list of Encoding) while saving the file and see the result. However, the default setting for encoding type is ANSI. This is a very interesting bug upto Windows XP, but Windows Vista supports the texts on Notepad under ANSI encoding as well.
Magic #3
rand() is a function that is used to add sample text quickly to an MS word document for testing purpose. The support team of Microsoft explains it, see the following link

Hope to see more of these interesting posts in future.
