Usually during "Patch Tuesday" every month, one or more of Microsoft's Surface tablets gets an automatic firmware update with some improvements for the products. Today's "Patch Tuesday" is a little different as Microsoft has elected not to offer any firmware updates for its Surface products for the first time since the tablets were launched.
The Surface history pages for all of the tablet models says there will be no firmware downloads for April, thanks to the release today of the Windows 8.1 Update, The pages all have information on how users can simply wait to get the update automatically or download it manually. It adds, "If you can’t install the update manually, you might be missing one or more of the required updates. Install all important updates, in particular KB 2919442, and restart Surface."
As we have mentioned, Windows 8.1 users have to download and install today's major update, which includes a number of improvements made mostly for mouse and keyboard users. 8.1 users who don't install these files won't be able to get any further updates for the OS. People who still have Windows 8 installed on their PC are not required to get the Windows 8.1 Update.
