Quote:Microsoft has shipped the typical monthly rollups for Windows 7 and 8.1 devices as the company fixes security and non-security bugs on the two platforms.

First off, there’s monthly rollup KB4503292 and security-only update KB4503269 for Windows 7.
 
The aforementioned rollup comes to resolve an issue hitting Internet Explorer and breaking down HTTP and HTTPS string character limit for URLs. In terms of security, Microsoft resolves issues in the Windows App Platform and Frameworks, the Microsoft Graphics Component, and the Windows Shell.
There are two known issues, one of which affects McAfee security products that could lead to the system no longer capable of booting. The second causes IE11 to stop working when loading Power BI reports.

As far as Windows 8.1 devices are concerned, they are provided with monthly rollup KB4503276 and security-only update KB4503290,
In addition to the fixes that are included in the Windows 7 monthly rollup, the Windows 8.1 release also brings fixes for an issue hitting the Preboot Execution Environment (PXE), while also resolving a vulnerability hitting Bluetooth connections.
