I just stumbled upon some cool W7 tweaks on SevenForums and figured I'd post them here.
The first one is a tweak to change the hover delay on Aero Peak/thumbnail previews in the taskbar. The original link is here, but I've written a resume here.
Open regedit.
Navigate to "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced"
Right-click and create a new DWORD called "ExtendedUIHoverTime".
Choose decimal and enter a time in milliseconds. I've chosen 200 and that works out fine.
Close regedit and restart explorer either by terminating and restarting the proces or logging out/in/restarting the computer
The next one also concerns the taskbar. It's a tweak to enable easy cycling through previews by clicking on the taskbar icon. Copy+pasta:
Launch regedit.exe (Win+R, then paste regedit.exe)
Navigate in the left tree control to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
Go to Edit->New->DWORD (32-bit) Value
Name the value LastActiveClick
Hit enter to assign the value and change it to 1
Restart Explorer and you're good to go.
My last tweak for you is really awesome. By creating transparent shortcuts in the taskbar you can group items in an easy way. Go to LifeHacker and find out how.
