Correction - Yahoo! Data Grid CLSID

Pretty much every news outlet appears to be reporting the incorrect CLSID for the Yahoo! Data Grid ActiveX component.  Alert reader Iain pointed this out to us.  It appears that the original mistake happened somewhere back in the chain of things and has simply been perpetuated...

The actual CLSID of the Yahoo! Data Grid: 5F810AFC-BB5F-4416-BE63-E01DD117BD6C

Almost all of the stories that we've seen have listed the CLSID having an extra "2" on the end.

And yes, I was bitten by the issue...  The programs that I wrote to set killbits used the incorrect CLSID.

So... I've gone back and altered the killbit setting apps.  The updated files are available at the links listed below:

The GUI version can be found here (KillBitGui-Feb08.exe - 4096 bytes - MD5: 9428b9c3778b68e768448ca52c7d8dfd)
The CLI version can be found here (KillBitCLI-Feb08.exe - 4608 bytes - MD5: 30c151ab6de460f5844e9b5826495911)

I'll also update older diary posts to reflect the correct CLSID because they have been linked from other sites.

(A big "thank you" to Iain for pointing this out...)

You need to update your link for the command line version. You forgot the tliston part.
