Which is sufficient considering 24 months were given to Windows 7 users to update to SP1, which was released back in February, 2011.
In case you don’t know Windows 8.1 is similar to a service pack, meaning it is free and provides hosts of new updates and security fixes. Microsoft reports on its Support website that Windows 8.1 falls under the Windows 8 lifecycle policy, which ends on January 10, 2023. However, the company also states that Windows 8 customers will have two years to move to Windows 8.1 starting this Friday, AKA the General Availability of the Windows 8.1 update, to remain supported under the Windows 8 lifecycle.
Windows 8’s mainstream support actually ends on January 9, 2018, followed by the extended support end date on January 10, 2023. This schedule also applies to Windows 8 Enterprise, Windows 8 Enterprise N, Windows 8 N, Windows 8 Pro and Windows 8 Pro N. With the 2-year limited support, Microsoft is essentially forcing updates on those who typically drag their feet in upgrading. After October 2015, users who are still using Windows 8 will no longer receive critical security patches, new features and improvements, and could possibly be locked out of third-party app updates as well. The only way to stay fresh and secure is to update to the latest version.
“Windows 8.1 builds on the foundation of Windows 8, and includes many enhancements and great new features in key areas like personalization, search, the built-in apps, Windows Store experience, and cloud connectivity,” the company states. “Windows 8.1 also introduces new manageability, mobility, security, user experience and networking capabilities for businesses.”
As we reported earlier Microsoft’s extended support for Windows XP SP3 is also coming to an end, so if you are still using XP. Now is the time to upgrade, and I wouldn’t recommend upgrading to Windows Vista. You have the choice of either Windows 7 or Window 8.
Windows 8.1 goes public on October 18, 2013. After that, the two-year countdown timer begins for Windows 8 vanilla.
