During April’s Patch Tuesday, Microsoft released a handful of updates for each supported version of Windows, including Windows 7. This operating system received numerous security and non-security patches, that should improve the overall stability and security of users.
One of these updates is the cumulative update for Windows 7 SP1 and Windows Server 2008, KB4015549. This update serves as a monthly rollup for both systems, and as a cumulative update, contains all the previously-released patches from previous updates.
The update is mainly focused on security improvements, and brings vulnerability fixes for the scripting engine, Hyper-V, libjpeg image-processing library, Adobe Type Manager Font Driver, Win32K, Microsoft Outlook, Internet Explorer, Graphics Component, Windows kernel-mode drivers and Lightweight Directory Access Protocol.
Microsoft also warns that the update comes with one known issue. Namely, users that have an AMD Carrizo DDR4 processor in their PCs won’t be able to install future updates upon installing this one. At the moment, there’s confirmed solution, as Microsoft promised a fix soon:
“If the PC uses an AMD Carrizo DDR4 processor, installing this update will block downloading and installing future Windows updates. Microsoft is working on a resolution and will provide an update in an upcoming release.”
Other than this problem, there are no other reported issues so far. However, if you encountered any additional problems upon installing cumulative update KB4015549, feel free to let us know in the comments below.
