Starting May 2014, Windows 8.1 without Update will no longer receive security updatesWritten by Ron on April 15, 2014 - 09:04AM @ronwinbeta
On April 8th, Microsoft rolled out the next big update to Windows 8.1, simply called Update. This new update brought forth numerous new enhancements for non-touch enabled devices. Now, Microsoft is reiterating that security patches for Windows 8.1 will no longer be available after May 2014.
"Since Microsoft wants to ensure that customers benefit from the best support and servicing experience and to coordinate and simplify servicing across both Windows Server 2012 R2, Windows 8.1 RT and Windows 8.1, this update will be considered a new servicing/support baseline. What this means is those users who have elected to install updates manually will have 30 days to install Windows 8.1 Update on Windows 8.1 devices; after this 30-day window - and beginning with the May Patch Tuesday, Windows 8.1 user's devices without the update installed will no longer receive security updates," Microsoft stated in an official blog post.
In other words, Windows 8.1 users will be required to install the the big Update, or else security updates released during Patch Tuesday in May will not be applicable. If you have yet to install Windows 8.1 Update, head over here to find out how.
