Quote:Microsoft’s April 2019 Patch Tuesday also includes monthly rollups for Windows 7 and 8.1, which are technically cumulative updates that come with both security and non-security fixes.
 
Windows 7 users are being provided with monthly rollup KB4493472 and security-only update KB4493448.
 
While you can check out the change logs of both updates in the box after the jump, it’s worth noting that the monthly rollup for Windows 7 introduces additional mitigations against the Meltdown and Spectre vulnerabilities discovered in early 2018.
 
“Provides protections against Spectre Variant 2 (CVE-2017-5715) and Meltdown (CVE-2017-5754) for VIA-based computers. These protections are enabled by default for the Windows Client, but disabled by default for Windows Server. For Windows Client (IT Pro) guidance, follow the instructions in KB4073119. For Windows Server guidance, follow the instructions in KB4072698. Use these guidance documents to enable or disable these mitigations for VIA-based computers,” Microsoft explains.
