Windows 7 is one of the most successful and popular operating systems from Microsoft. Despite the release year, it is still installed on many personal computers as the main OS. The recognition of the "seven" was deservedly - because of the stability, convenience and optimization. This article discusses this operating system, and in particular the version of "Windows 7 Professional".

OS history
The first release of this operating system was released at the end of 2009. The rather unfortunate predecessor of Vista did not give the company the right to make a mistake. The new operating system came out less than three years after Vista, which is a very short time.
Despite this, the software gained tremendous popularity and held leadership among users of all platforms in the world until March 2017, when Windows 10 took the lead.
Early 2015Microsoft officially stopped supporting the "seven" and the release of updates, completely switching to Windows 10. This did not greatly affect the position of the hero of the review, since a large percentage of people still consider it the best operating system.
In Windows 7, just like in Vista, Aero mode has appeared. It replaces the standard interface design. Compared to its predecessor, the "seven" Aero has been radically redesigned. With the release of G8, the platform switched to a new interface - metro UI. However, Windows Aero is still praised by users for its convenience and conciseness.
