Windows 7 RC help and support corrupted

I installed windows 7 RC on my samsung NC10. It ran quite fine for a few days.
Suddenly today when I opened the "help and support", i saw this meaningless screen, other topics are also corrupted. please see the screen-shot and please help .

Well apart from it being 'reusable' backwards, I'm unsure.
I'd run a virus scan just to make sure everything is ok...

What language are you using?

I am using standard en-US .
And I m sure that the system is clean. I installed the same version in my PC and that runs fine. Sometime s I solve this wierd problem by overwriting the help files from the working win 7 (from my pc) , but after a few days, it reverts back

Was this an upgrade or clean install (the pc with the odd word)?

I did a Google search, ened up with mostly broken links, but did find this page.

No explation what elbasuer is

Vista User Guide - Google Books

Nice find... Still, it's pretty weird though?

Definitely weird, I never come across that before

If you have a Vista Computer, try copying the Winhlp32.exe and winhelp32.exe.mui to the proper directories.

make a copy of both files first.

I'm just wondering if it's something that has been left in there by a wayward engineer?

Don't ask why, but I typed the word into the Help and Support and got 0 results.
