As Windows 10 is released so is Microsoft ending its mainstream support for its older products like Windows Xp whose support was ended 2 years ago.
Windows 7, which was being the most widely used version of windows, is now shutting down its mainstream support too.
According to Microsoft product support lifecycle database all version of windows 7, which includes Windows 7 Starter, Home, Home Premium, Ultimate, Enterprise, are not going to get free further help and support from Microsoft.
Microsoft seems to be targeting Windows 7 users to shift to Windows 8.1 or Windows 10. Windows 7 mainstream support ends mean that you have to pay for any software issues in future but this does not mean that extended support will also be ended, it will end by 2020.
However you should not worry as any security patches will still be given by Windows 7. Windows 7 was released in late 2009 and is widely used across world about 100 million users as it was stable release after Windows Vista.
