身分證字號規則：
字母(ABCDEFGHJKLMNPQRSTUVXYWZIO)對應一組數(10~35)，
令其十位數為X1，個位數為X2；( 如Ａ：X1=1 , X2=0 )；D表示2~9數字
Y = X1 + 9*X2 + 8*D1 + 7*D2 + 6*D3 + 5*D4 + 4*D5 + 3*D6 + 2*D7+ 1*D8 + D9
如Y能被10整除，則表示該身分證號碼為正確，否則為錯誤。

How to remove MSN Messenger advertisement?

When you have the HEX editor running, follow these steps:

1. Make sure you are not running messenger. Right-click its icon in the system tray, and from the menu select Exit
2. Now you'll need to locate the messenger executable msnmsgr.exe, it will normally be in \Program Files\MEN Messenger\
3. Make a backup of the file. Right-click msnmsgr.exe and from the menu choose Copy. Now right-click on an empty area in the same folder, and select Paste from the menu. The backup will be named Copy of msnmsgr.exe. If you ever want to get back to the original file, simply delete msnmsgr.exe, and then rename Copy of msnmsgr.exe to msnmsgr.exe
4. From the menu in XVI32, choose File > Open, locate msnmsgr.exe, and open it
5. From the menu, select Address > Goto, select hexadecimal, and enter D236D, press OK
6. The value selected will be 74, simply type EB to replace it (so 74 becomes EB)
7. Repeat step 5 & 6, but for the value to search for now enter D23AA (step 6 stays identical)
8. When done select File > Save from the menu, and exit XVI32
9. Reopen Messenger 6, now without the ads!
