It seems that Microsoft really decided to force users to migrate to Windows 10, since it recently ended support for Windows 7, and now decided to apply the same idea to Windows 8 that stopped having support from the 12th January 2015. Initially this action was only scheduled for January 9, 2018.
Normally, Microsoft gives ten years for these situations, Windows 8 was launched in 2012, thus completing 4 years, and apparently it will not be as lucky, but it seems that the company is trying to compel users of previous versions of the operating system migrating to the Windows 8.1 version, which is a Windows 8 service pack, and not another operating system.
For those of you who want to get to Windows 10, it's a good idea to upgrade to Windows 8.1, which can be done for free. O Update for 8.1 is what grants the availability for the latest released version of Windows.
It can also be remembered that A Microsoft recently considered risky the continued use of Windows 7, alleging problems related to the compatibility of hardware, software and user security in which Microsoft will stop providing assistance.
Still using Windows 8?
