Windows 7 have a nifty feature which combines the windows of opened applications under the same taskbar button. If you don't like it you can always turn it off.
Not only that you can share files — like documents, images, and PDFs — without having to email them as attachments. You can share the whole folder containing the documents.
If you know how many years or months you got left until the retirement or any other event or project in your life, Excel can return you the exact date and the number of days left to reach it.
