So I can’t say that I’m surprised users are reporting issues with the fix from yesterday. Specifically, it is causing Windows 7 PCs to crash randomly and frequently and upon the removal of the patch, system performance seems to return to normal.
That being said, it may be best to remain in a holding pattern since it appears that more harm is being caused in production environments by installing the patch as opposed to rampant infections due to users visiting bad sites on Internet Explorer (another reason why you should be using Chrome, Firefox, or even Edge!) At some point, the “fixes” in this patch (hopefully without the crashing) will probably get rolled into a cumulative update in the future so most of us can afford to wait.
Stay tuned!
