Greetings,

There is a big difference between the old and new for this registry key UserPreferencesMask located at HKCU\Control Panel\Desktop. On 32-bit Windows, this is a 32-bit value. On 64-bit Windows, this is a 64-bit value. Example: 9012038010000000 (or 90,12,03,80,10,00,00,00) with 8 pairs of 2 instead of 4 pairs of 2.

I've been Googling a lot trying to figure out how to determine what options are actually set by the above example. I found a resource at MSFN forums with a text file attachment, but I am unable to download it because I am unable to login or register an account due to an IP Driver/database error message that the forum produces, so I am not sure if this text file has what I am looking for.

You can find the Microsoft TechNet documentation for the 32-bit version of this registry key at http://technet.microsoft.com/en-us/library/cc957204.aspx. It is no use. From my research, such as at https://social.technet.microsoft.co.../thread/d95ce351-ef0c-415d-ac55-80553b74ce52/, the values for the 64-bit version of this registry key are totally and entirely different from the 32-bit version; the same values do not enable the same functions.

So, I'm kind of at a moot point. :( I don't know where to go or how to reverse engineer this 9012038010000000 value to know what it is applying and doing.

EDIT: Found it. See http://www.sevenforums.com/tutorials/1908-visual-effects-settings-change.html under OPTION TWO. And thanks to http://communities.vmware.com/thread/332587?start=0&tstart=0 that I was lead to that article.
