Installation failures

Some Windows 7 users reported that KB4507449 failed to install on their devices.

I recently did some updates and the computer crashed during kb4507449 install. i restarted and redid the updates and all but this one installed. i manually downloaded the update and tried installing from the .msu package but it fails every time. is there something i can do to get this installed? do i need to clean something out?

Quick Workaround

You need to install the latest servicing stack update KB4490628 before installing KB4507449 as mentioned on the official support page:

Microsoft strongly recommends you install the latest servicing stack update (SSU) for your operating system before installing the latest Rollup. SSUs improve the reliability of the update process to mitigate potential issues while installing the Rollup and applying Microsoft security fixes.

If you are one of those who have encountered a similar situation, you can download and install the latest SSU now. However, you don’t need to reboot your system after installing this update.

McAfee security products bug

This one is a known issue and Microsoft already listed it on the official update page. The company acknowledged the fact that it’s collaborating with McAfee to resolve update issues affecting systems running McAfee security products such as McAfee Endpoint Security (ENS) Threat Prevention 10.x, McAfee VirusScan Enterprise (VSE) 8.8, and McAfee Host Intrusion Prevention (Host IPS) 8.0.

This issue may lead to a situation where your system may fail to respond on startup.

Unfortunately, there is no workaround available to fix this problem but Microsoft promised to release a permanent fix very soon.
