Back in April, Microsoft told Windows 8.1 users to refresh their system with the new Update released earlier that month. Customers were advised to do so before May 13, the next Patch Tuesday, in order to receive additional security patches from Microsoft.
"This update will be considered a new servicing/support baseline," a Microsoft engineer said. "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."
However, on Monday, Microsoft's Brandon LeBlanc jumped onto the Windows Experience Blog and announced that the Windows 8.1 Update due date has moved back another 30 days so that customers have plenty of time to download and install the mandatory Update.
"While we believe the majority of people have received the update, we recognize that not all have. Having our customers running their devices with the latest updates is super important to us. And we're committed to helping ensure their safety. As a result, we've decided to extend the requirement for our consumer customers to update their devices to the Windows 8.1 Update in order to receive security updates another 30 days to June 10th," he writes.
"As noted previously, consumer customers who do not update their Windows 8.1 devices to the Windows 8.1 Update by this new deadline will no longer receive updates. We're confident that within the next month, the majority of the remaining customers who haven't updated their devices to the Windows 8.1 Update will be able to do so," LeBlanc adds.
