Backup & Security features in Vista

Speed up your PC’s performance:

Windows Vista introduces a new concept for adding additional performance to a running system. Windows ReadyBoost™ lets people use flash memory on a USB 2.0 drive, SD Card, Compact Flash, or other memory form factor to provide additional memory cache—memory that the computer can access much more quickly than it can access data on the hard drive. Insert a USB 2.0 memory drive with at least 512 MB capacity. When prompted, click use this device to speed up my computer.

Recover a previous version of a document:

Windows Vista introduces a new feature: Previous Versions. This allows you to “roll back” the clock to an earlier version of a file that you may have accidentally saved over or edited. In the Documents Explorer, open a document, edit it, save it, and then close it. While selecting the document, choose the Previous Versions option on the command bar, which will bring up a list of previously saved versions of the individual file. Choose a previous version and Windows Vista will restore your file to that version. Careful: all edits since that version will be lost.
