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 orThis PC in Start menu/screen or Desktop and select Properties from the menu.
In Windows XP, see what's written in the System section.
In Windows Vista, 7, 8 and 8.1, see what's written in the Windows edition section.
To check whether your OS is 32-bit (x86) or 64-bit (x64), see the System type line in Windows Vista and later. In Windows XP, if there's no mention of "x64" in System section, then the OS is 32-bit edition.
Windows 8 and 8.1 can be fully controlled with touch screens. If you do not have keyboard and mouse with your Windows 8/8.1 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 Modern UI/Metro apps and items on App bar and menus, touch the item once.
- To reveal Back and Forward buttons in Modern UI apps, touch an empty space.

- 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 Modern UI apps that support the feature.
