Win7 – Faster Thumbnail Previews

The taskbar shows thumbnail previews of opened windows when you hover the mouse over the program icon. By default, it takes a little time for the preview to appear. Make the previews appear faster with this registry tweak:

Use Windows Key  +R to get a run box
Enter regedit and hit your ENTER KEY
Navigate to HKEY_CURRENT_USER\Control Panel\Mouse.

On the right, open the MouseHoverTime key and changes its value from the default 400 to around 150. Decreasing it further may cause problems.

Win7 – Boost performance with ReadyBoost

ReadyBoost improves your system performance by using faster USB Flash Drives instead of slower hard disks for system operations. It works best using flash drives with at least 1 GB of storage.

Simply insert your flash drive, and if it meets certain performance benchmarks, Windows 7 will ask you if you want to use it for ReadyBoost and recommend the size to reserve.
