Won't do you any good. The updates now are all cumulative, including security-only.
This patch was added even to that, not just the security and quality rollup.
Going forward, if there's any doubt whether your CPU may get flagged incorrectly, you can't update. Even worse, again, the update, once installed, cannot be removed. You have to either restore a backup, or reimage from scratch.
If you're not already making routine backups of your OS drive, I strongly recommend grabbing Veeam Endpoint Backup Free and start, before you install any updates going forward.
Yea, I system restored, then installed all but the two April updates. Seems to not be annoying me now. So I guess that's the end of security updates for my windows 8.1 system that is supposed to still be in full support. That's the issue.
