[Windows 8] Input method still remains after removing it?

Well, I've upgraded to Windows 8 recently, I tried to install Vietnamese input language method, but then I didn't feel like familiar to it, so I decided to remove it, well, everything was okay at that point.
After that, when I was working, I noticed that there's still Vietnamese input language method when I click on "ENG" button on task bar, that's weird, right? Afterwards, I searched and tried many ways (I even asked on a big forum: http://superuser.com/questions/522696/how-can-i-remove-an-input-method-completely-in-windows-8) to remove it but couldn't help... until this post:

Summary:

- Just add Vietnamese (or the language which you want to remove), then remove it again!

Hope it can help you out :)

Oh yeah, as I commented below, the above solution doesn't work, but today, finally, I got rid of it.
Actually, I almost surrendered and I have been having to stand it until today. I was starting learning Japanese, so I added Japanese Input Method to Language Bar and I got 3 entries English, Vietnamese, Japanese. The problem is using Windows+Space to switch between those 3 entries is really annoying, so I had to work my ass off on this problem once more time. And lucky me, I found this thread:

http://answers.microsoft.com/en-us/windows/forum/windows_8-desktop/remove-english-us-keyboard/16f81314-8c4f-4315-baf0-c6518449d8ae

After reading it, I took a look at my startup programs and did some "trial and error", logging in/out several times. Finally, I found out that "Unikey"  (a Vietnamese Input Method software that I was using) is the root cause of the problem, whenever it's started, it adds a Vietnamese entry to Language Bar - that sucks!

Well, I had been using Unikey for years, but at that time, I had to give it up! But then fortunately, after googling, I found another app which can do the same awesome job but DOES'T add anything to Language Bar, and it's:

http://www.trankynam.com/gotv/

I had been using that app on my Android phone, but didn't know it's also available on many other platforms, of course, includes Windows.

So... finally, after a very long time, my problem is solved completely xD

And one more thing, just a thought... that guy, TranKyNam is awesome indeed, he has a few other apps than gotv that I haven't had chances to try, but they looks cool also. I will definitely remember his name xD

Free Grep tool for Windows

It's findstr, which is already available in Windows (XP), did you know?

To get more details, you can refer this link: http://technet.microsoft.com/en-us/library/bb490907.aspx, or  type this command in the Command-line:

findstr /?

Here's a typical example to show how to use:

• If in the Terminal of Unix you type:

grep -R "hi there" \data

• Then in the Command-line of Windows you can type:

dir /B /S C:\data | findstr /f:/ "hi there"
