Here is a hot readyboot tip for windows7. especially if you are running in low memory.
What is 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.
How can I use that?
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.
You’re Done!
