If you want to reduce the time needed for installing your OS you can use nLite addons to create your own bootable image of Windows.
Addons are third-party applications developed by other producers than the nLite developers, designed to be included in nLite as addons. They are specially customized so that they can be added to nLite in order to create a preinstall image of Windows to ease a user's work when reinstalling Window on their computer.
You just add these addons, create your image and when you reinstall your Windows all your favorite programs will be there just like they were before. It's a fast and easy way to keep a backup especially if you have a lot of programs installed on your computer.
Skype is a free download that lets you use your computer to make telephone calls. Calls from one Skype user to another are free, wherever they are in the world. You make calls using usernames rather than traditional phone numbers, and an instant-messaging client (for text chatting) is included.
There are a number of paid add-ons: SkypeOut, for calling ordinary phones; SkypeIn, which provides a real phone number so non-Skype users can call you; and Skype Voicemail, to answer your calls when you are away from the PC. With these services, Skype can provide its users with a rich set of features at low cost. This is a business version of Skype.
