i think i know how,
but it haven't been tested yet.
first you set your users pic to a blank 1,
s you will see only the frame.
after that you use a res hacker to edit explorer.exe.
in the explorer.exe you go to bitmaps and then navigate to those files and replace them with blank images as well,
7013, 7014, 7015, and 7016
the 7013 is the task bar 1 (not proven only by scale)
so just replace your acc pic to blank pic
and the 7013-7016 bitmaps to blank images
you can also wait for me to upload the edited 1 a made.
im uploading it right now
here is my edited explorer.exe,
MEGAUPLOAD - The leading online storage and file delivery service
note, i use win 7 ultimate 32bit,
so if you use other o/p pls make a restore pont first.
and not responsible for nothing that might happen to your win/comp
