Download KB4503269 and KB4503292

Microsoft just pushed security-only update KB4503269 and monthly rollup KB4503292 to all Windows 7 users. These updates patched a series of security and non-security issues that affected the OS.

A quick reminder, the end of support deadline for Windows 7 falls in January 2020. Microsoft already announced it would stop releasing security and feature updates to the OS beyond that date.

Therefore, you need to upgrade your system to Windows 10 as soon as possible to keep your system protected. If you choose to stick to Windows 7, Microsoft will charge you a handsome amount for Extended Security Updates.
