Using keyboard shortcuts
can greatly increase your productivity, reduce repetitive strain, and help keep
you focused. For example, highlighting text with the keyboard and pressing Ctrl
+ C is much faster than taking your hand from the keyboard, highlighting the
text using the mouse, clicking copy from the file menu, and then putting your
hand back in place on the keyboard. Below are our top 10 keyboard shortcuts we recommend everyone memorize and use.

Ctrl + C or Ctrl + Insert

Copy the highlighted text or selected item.

Ctrl + V or Shift + Insert

Paste the text or object that's in the clipboard.

Ctrl + Z and Ctrl + Y

Undo any change. For example, if you cut text, pressing this will undo it. This can also often be pressed multiple times to undo multiple changes. Pressing Ctrl + Y would
redo the undo.

Ctrl + F

Open the Find in any program. This includes your Internet browser to find text on the current page.

Alt + Tab or Alt + Esc

Quickly switch between open programs
moving forward.

Adding
the Shift key to Alt + Tab or Ctrl +
Tab will move backwards. For example, if you are pressing Alt + Tab and pass
the program you want to switch to, press Alt + Shift + Tab to move backwards
to that program.

Windows Key + Tab to switch through
open programs in a full screenshot of the Window.

Ctrl + Back space and Ctrl + Left arrow / Right arrow

Pressing Ctrl +
Backspace will delete a full word at
a time instead of a single character.

Holding down the Ctrl key while pressing the left or right arrow will move the cursor one word at a time instead of one character at a time. If you wanted to highlight one word at a time you can hold down Ctrl +
Shift and then press the left or right arrow key to move one word at a time in that direction while highlighting each word.

Ctrl + S

While working on a document or other file in almost every
program pressing Ctrl + S will save that file. This shortcut key should be
used frequently anytime you're working on anything important.

Ctrl + Home / End

Move the cursor to the beginning or end of a document.

Ctrl + P

Print
the page being viewed. For example, the document in Microsoft Word or the
web page in your Internet browser.

Page Up / Space bar and Page Down

Pressing either the page up or page down key will move that page one page at a time in that direction. When browsing the Internet pressing the space bar will also move the page down one page at a time.
If you press Shift and the Space bar the page will go up a page at a time.

Windows 7 is simpler to use, more responsive, and full of new possibilities. So i decided to put some reasons to buy Windows 7.
here a my Top 5.

A better desktop & Smart Search

A better desktop. Windows 7 gets you around your PC faster than ever. The taskbar has bigger buttons and full-sized previews—and you can pin programs to it for one-click access. Jump Lists provide shortcuts to files, folders, and websites. And Snap, Peek, and Shake give you easy (and fun) new ways to juggle all those open windows.
Type in the Start menu search box, and you'll see results instantly, grouped by category—documents, pictures, music, e‑mail, and programs. Search in a folder or library, and you can fine-tune your search with filters like date or file type—and use the preview pane to peek at the contents of your results.

Easy sharing with HomeGroup & Built for Speed

Sharing files and printers on your home network should be simple. With HomeGroup, it finally is. Connect two or more PCs running Windows 7, and with a minimum of fuss you can start sharing music, pictures, videos, and documents with other people in your home.
Windows 7 has key performance improvements to take up less memory and run background services only when you need them. It's designed to run your programs faster and to sleep, resume, and reconnect to wireless networks quicker. And with 64-bit support, you can take full advantage of the latest in powerful 64-bit PCs.

Better wireless networking & Windows Touch

Connecting to wireless networks on your laptop—formerly a bit of a hassle—now takes just a couple of clicks. Choose from the list of available networks in the taskbar, click one, and then connect. Once you've connected to a network, Windows will remember it so you can connect again later automatically.
Use your fingers to browse the web, flip through photos, and open files and folders on a touchscreen PC—for the first time, Windows includes true multitouch technology. With gestures for zooming, rotating, and even right-clicking, it's a whole new way to work with your PC.

Plays well with devices & Watch, listen, and stream

Device Stage, a new feature in Windows 7, works like a home page for things like portable music players, smartphones, and printers. When you plug a compatible device into your PC, you'll see a menu with information and popular tasks like battery life, how many photos are ready to be downloaded, and printing options.
Internet TV, part of Windows Media Center, gathers programming from sites all over the Internet—shows, sports highlights, video podcasts, and more. Add a TV tuner, and your PC becomes a digital video recorder you can use to watch, pause, and record live TV. And with new features in Windows Media Player 12, you can enjoy your media library around the house—or around town.

Internet Explorer 9 and Windows Live & Nag-free notifications

Windows 7 unleashes the full power of Internet Explorer 9, from its stunning hardware-accelerated graphics to the ability to launch favorite websites right from your taskbar. You'll also get the many possibilities of Windows Live, free: create photo albums and movies, chat in HD, and share your stuff anytime, anywhere.
Action Center, new in Windows 7, puts you in control of maintenance and security messages. You can turn notifications on or off for things like Windows Defender or User Account Control. If Windows needs your attention, you'll see a notification on the far right of the taskbar. Click it, and you'll get suggested fixes for any problems.
