Microsoft’s October 2019 Patch Tuesday is a go and now rolling out to Windows users around the world. Perhaps the most interesting thing about this month’s patch event is that it is relatively light.

Certainly, compared to Patch Tuesday rollouts over the last year, October 2019 is small. Over previous events, Microsoft has patched between 80 and 100 vulnerabilities each month, alongside active zero-day vulnerabilities.

For October 2019 Patch Tuesday, Microsoft says there were no zero-days. Additionally, the number of normal patches was also reduced, with only 59 bugs handled. Of those bugs, only nine were deemed “critical” by Microsoft’s vulnerability threat rating.

You can check out the list of patches at the bottom of this page.

Patch Problems

With a reduced sized Patch Tuesday, hopefully Microsoft can avoid problems that have persisted with larger patches. Namely the company has been rolling out bulky updates which solve bugs but usually create all new ones.

Last month, Microsoft confirmed its Patch Tuesday cumulative updates caused issues with audio. Gamers had reported inconsistent audio performance across games on Windows 10 1903 since September 10. Microsoft acknowledged the issue in a support page. Redmond said KB4515384 was caused by a “compatibility” change with some audio partners.

Yesterday we reported on the company’s recent October 3 patch. This required patch was sent out by Microsoft to squash a bug between Internet Explorer and printers. It looks like this update is now causing all new problems for Windows users. Indeed, Microsoft was forced to reissue KB4524147.
