The quickest way to find out details about installed Windows is to use keyboard shortcut Windows Key+Pause. The latter key might be named Pause/Break on some keyboards.
Other method is to right-click My Computer/Computer in Start menu or Desktop and select Properties from the menu.
In Windows XP, see what's written in the System section.
In Windows Vista, 7 and 8, see what's written in the Edition section.
Windows 8 can be fully controlled with touch screens. If you do not have keyboard and mouse with your Windows 8 tablet, you can use the following gestures. "Touch" here means the same as "press" or "tap".
- To scroll horizontally or vertically, touch an empty space with your finger (not on Tiles, icons, App bar, menus, etc) and drag to the left and right or up and down. The faster your dragging gesture is, the further scrolling goes.
- To launch Metro apps and items on App bar and menus, touch the item once.
- To reveal Back and Forward buttons in Metro apps, touch an empty space.
- To select items (for example, Tiles on Start screen), flick them - touch an item and drag down a little.
- To reveal Charms bar, swipe in from the right edge of screen.
- To cycle between open Metro apps and the Desktop, swipe in from the left edge of screen and lift your finger.
- To reveal a list of open Metro apps, swipe in from the left edge of screen and then, without lifting your finger, drag back to the left a little. You can then touch/tap an item to view it full screen, or drag an item to the right to view two Metro apps side by side.
- To reveal App bar, swipe in from the top or the bottom edge of screen. To hide the bar, touch anywhere outside App bar. The bar is available only in these Metro apps that support the feature.
- To simulate mouse right-click in traditional Desktop programs, touch and hold for a second.
