I recently installed Windows 7 Pro x64 and I had a few questions about tweaking some things. On Vista I could easily add/remove links from the nav pane in explorer, but now there's this Homegroup item I just can't get rid of. I tried this reg hack and it worked at first, but now it's back. Is there a more permanent solution to get rid of it? A bit redundant with Network being down there, and stupid MS for not letting us remove junk. 
Also, in Vista I used the Ave ThumbnailResizer to increase the size of the taskbar thumbnail previews, but it doesn't work in 7. Anyone else know of a way to do it?
Thanks.
