Aero Peek Aero Peek expands on Vista's Aero graphical interface. If you have many windows open, Peek brings the window you want to focus on to the front, while turning all other open windows into transparent "glass sheets." Peek also works on the desktop. If you mouse over the "Show Desktop" control at the far right of the taskbar all windows on the desktop turn to glass, allowing the entire desktop to be seen.
Sharing with HomeGroup
HomeGroups let you easily link Windows 7 computers on your home network to share pictures, music, videos, documents and devices such as a printer. In order to s
et up a HomeGroup, a user's Network Location needs to be set as "Home" in the Network and Sharing Center. When you create a HomeGroup, you specify which media files, folders and devices you want to share, and create a password so that o
nly people with that p

assword can join the
HomeGroup.
Media Streaming Options
Media Streaming in Windows 7 has been simplified to share photos, video and music with other PCs on your home network using the new Homegroup feature. Remote Media Sharing, a new feature in the Windows 7 release candidate, allows users to stream information over the Internet to share media remotely. Media Streaming Options lets you restrict
which specific PCs have access to your media by choosing "more streaming options..." from the Windows Media Player "Stre
am" menu.
Play To
Once Media Streaming is enabled on your Windows 7 PC, the "Play To" feature lets you to send media to other Windows 7 PCs or devices in your network and play it
using a remote control window. From Libraries

within Windows Media Player or Windows Explorer, you can right-click on your media and send it off to another devic
e. For example, you can send video clips to a television, or music to anot
her laptop that's connected to speakers.
Aero Snap

Maneuvering between
windows is a pain, and comparing the content of two windows side by side requires awkward resizing that never quite works. Aero Snap is a feature that allows users to snap any two windows side by side. You grab a window and move your mouse to the edge of the screen and the window will fill half the screen. Repeat with the other window and they are locked next to each other.
