Welcome To The Party, Pal!— John McClane, Die Hard (1988)
Every second Tuesday, Microsoft drops its monthly batch of security patches — and sometimes, the cure is worse than the disease. Broken printers, BSOD loops, failed authentications, and zero-days are just some of the wreckage left behind.
PatchBoy tracks the fallout so you don't have to. A few days after each Patch Tuesday, we publish a report of real-world issues surfacing across Reddit, BleepingComputer, and beyond — and we keep updating it as the dust settles.

Frequently Asked Questions
What is Patch Tuesday Fallout?
▶
Every second Tuesday of the month, Microsoft releases security and quality updates for Windows and related products. While most updates go smoothly, some cause unexpected problems — broken printers, crashed services, failed logins, and worse. This site tracks those real-world issues so IT professionals and home users alike can make informed decisions about when and how to update.
How does the report work?
▶
A few days after each Patch Tuesday, we publish an initial report based on community feedback from places like Reddit's r/sysadmin, BleepingComputer, and Microsoft's own support channels. We then update the report at the 72-hour and two-week marks as the picture becomes clearer — including any out-of-band fixes Microsoft releases.
Isn't this info available elsewhere?
▶
It is — and PatchBoy is the first to admit it. The goal here is to pull it all together in one place with consistent formatting, direct links to sources, and a timeline view so you can track how issues evolve over the weeks following each release.
Are you claiming credit for discovering these issues?
▶
Absolutely not. PatchBoy stands on the shoulders of giants — the researchers, sysadmins, and journalists who surface these issues first. Every report links back to original sources. We're aggregators and translators, not discoverers.
Should I delay installing updates based on this site?
▶
That's ultimately your call and depends on your environment. Home users generally benefit from patching promptly. IT professionals managing large deployments often wait a week or two to see if issues emerge — which is exactly what this site helps you assess. Always weigh the security risk of not patching against the operational risk of a problematic update.
