From the WSUS and Windows Update Teams Blogs: Windows 8.1 Update (KB 2919355) prevents interaction with WSUS 3.2 over SSL There is a known issue which causes some PCs updated with the Windows 8.1 Update (KB 2919355) to stop scanning against Windows
Server Update Services 3.0 Service Pack 2 (WSUS 3.0 SP2 or WSUS 3.2) servers which are configured to use SSL and have not enabled TLS 1.2.
When Microsoft releases an update that resolves the issue, you may re-enable HTTPS on WSUS.
Microsoft plans to issue an update as soon as possible that will correct the issue and restore the proper behavior for Windows 8.1 Update KB 2919355 scanning against all supported WSUS configurations. Until that time, we are temporarily suspending the distribution of the Windows 8.1 Update KB 2919355 to WSUS servers.
You may still obtain the Windows 8.1 Update (KB 2919355) from the Windows Update Catalog or MSDN. However, we recommend that you suspend deployment of this update in your organization until we release the update that resolves this issue. You may also find the workarounds discussed in this article to be useful for testing this Windows 8.1 Update for your organization. Thank you for yourpatience during this time.

As previously mentioned, on April 2nd 2014, Microsoft released Windows 8.1 Update 1 to MSDN/TechNet subscribers. The general public Windows 8.1 users will get the Update (KB2919355) on April 8th via Windows Update and not the Microsoft Store as was the case in the past. Also at its Build 2014 conference, Microsoft has revealed that a future update to Windows 8.1 will resurrect the Start menu.
Microsoft’s Terry Myerson announced Windows 8.1 will soon get a new version of the beloved Start menu back. A preview of the long awaited return of the Start Menu in Windows 8.1 was made during a surprise announcement on Wednesday April 2nd.
But as one famous baseball player said: The Start Menu is not back till its back!
Windows 8.1 Update 1 April 2nd, 2014
Update 1 is now available on TechNet and MSDN for download, everyone else will need to wait until April 8th (AKA Patch Tuesday).
So is this update worth all the effort and does it make things easier for desktop / laptop users with a keyboard and mouse. The answer is yes and no. The big no is that Microsoft still refuses to add a full-fledged ‘Start Menu’. But there are a lot of improvements worth talking about and some near misses.
Before I dive into the details be prepared for a time consuming upgrade not from the Microsoft store but via Windows Update on April 8th (Patch Tuesday). Start by running Windows update to make certain all previously release updates are installed (which is a requirement) then the Windows 8.1 update 1 is downloaded (KB2919355).
Note: Important All future security and nonsecurity updates for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 require this update to be installed. We recommend that you install this update on your Windows RT 8.1, Windows 8.1, or Windows Server 2012 R2-based computer in order to receive continued future updates.
You can expect update 1 to take 15 minutes or more to install depending on your computers CPU speed and most importantly the disk drive as this is a disk intensive update. Finally when the ‘Restart’ button is displayed wait about 2 minutes or until the drive activity finally stops (Note: you may need to wiggle the mouse a few times to get the drive to stop churning). Then click the ‘Restart’ button to complete the update, be prepared for another 5 minute or so wait while Windows finishes installing the update during which your display may go black for about a 15 second period. Finally Windows will load and go straight to the ‘Desktop’ except touch based devices which go to the ‘Start’ screen.
Top of the list of improvement is that Windows 8.1 after the update is installed will boot straight to the desktop on none touch based computers which are by far and away the majority of users.
Start Screen: Also in the ‘Start’ screen (AKA: Metro / Tiles), you can bring the taskbar up, with a quick downward mouse curser movement to the bottom of the display. You need to position the mouse cursor about an inch above the bottom of the display and then quickly move to the bottom edge. It won’t be displayed if you move the mouse too slowly, you need to be fast. When you return from the Desktop to the Start screen the taskbar will also be briefly displayed. You can hold it open by keeping the mouse cursor in the taskbar area.
Start screen - Power Off button The Power button is now displayed in the upper-right of the Start screen. Click on the Power button displays the basic ‘Sleep’, ‘Shut down’ and ‘Restart’ which makes it easy for touch screen users but unfortunately there is no power button in the ‘Desktop’ environment thus forcing you to either press the Win+X key (or right click on the ‘Start button’) to shut down the PC.
Start screen: Search button The 'Search button' is now part of the Start screen. This makes 'Search' easier to get at, but unfortunately with Bing now part of what a search returns, you can never be 100% certain you are doing a local search or searching the Internet as the search options displayed just above the search box can be easily overlooked.
Resize the tiles: I never did like the oversized tiles on the start screen, you can resize them down to something more manageable allowing you to place more of your frequently used tiles on the start screen instead of clicking to move down to the overly crowded ‘Apps’ screen.
Smaller "resized" tile.
Desktop Users: The Windows Store is now pinned to the taskbar by default. Also you can pin most apps located on the start screen to the taskbar. The downside is that the start screen is so cluttered with apps you may have a hard time trying to find the one you are looking for. This example shows how to pin MS Word to the Desktop taskbar.
What is missing is an easy way to pin or create a shortcut on the desktop as the taskbar can only pin a limited number of apps before you run out of space.
Force Windows to boot straight to the Desktop:
If after you install ‘Update 1’ you find the PC still does not boot straight to the desktop you can change the way Windows boots as follows:
1) Right click on the Taskbar and select ‘Properties’
2) Click on the ‘Navigation’ tab.
As usual clicking on the Start Button in the taskbar will send you back to the start screen. You still need to right click or press the Win+X key to access for instance the ‘Control Panel’, once opened you can pin the Control Panel to the ‘Task Bar’ by right clicking on the control panel icon displayed in the task bar. After you exit the control panel the icon remains in the task bar making it easier to get to.
From the Windows Experience Blog: http://blogs.windows.com/windows/b/windowsexperience/archive/2014/04/02/windows-8-1-update-important-refinements-to-the-windows-experience.aspx Improvements for business customers: We are introducing several key improvements for businesses such as Enterprise Mode Internet Explorer (EMIE) and extended Mobile Device Management (MDM). EMIE enables Internet Explorer 8 compatibility on Internet Explorer 11 so companies can run existing web-based apps seamlessly on Windows 8.1 devices. And with extended MDM, we are introducing additional policy settings that can be managed with whatever MDM solution an enterprise chooses including whitelisting or blacklisting Windows Store apps and websites. Look for a blog post later today on the Windows for your Business Blog that discusses these in greater detail and a post on the Springboard Series Blog on deployment guidance for the Windows 8.1 Update.
