Key Features

This operating system supports Unicode. Instant search bar now recognizes more languages.

This OS supports multi-touch control .

All versions of the OS include 50 new fonts. The existing fonts are refined to correctly display all the characters. Windows 7 is the first version of Windows, which includes more fonts for displaying non-Latin characters than for displaying Latin characters. The font control panel has also been improved - by default it displays only those fonts for which the layout is installed in the system.

Windows 7 supports aliases for internal folders. For example, the Program Files folder in some localized versions of Windows was translated and displayed with the translated name, but remained in English at the file system level. In addition, the system (except for the version of Windows 7 Starter and Windows 7 Home Basic) contains about 120 background images that are unique to each country and language version. So, the “Russia” theme is included in the Russian version with six unique high-resolution wallpapers.

An additional advantage of Windows 7 can be considered a closer integration with the manufacturer of drivers. Most drivers are detected automatically, and 90% of the time are backward compatible with drivers for Windows Vista.

Windows 7 also improves compatibility with older applications, some of which cannot be started in Windows Vista. Especially it concerns old games developed under Windows XP. Also in Windows 7, Windows XP Mode appeared, which allows you to run old applications on a Windows XP virtual machine, which provides almost full support for old applications.
