Microsoft Patch Tuesday – December 2025: Yet Another Glorious Parade of Bullshit

Ah, joy of all bloody joys, it’s December’s Patch Tuesday again. Microsoft’s monthly love letter to sysadmins everywhere, filled with delightful little surprises guaranteed to ruin your week. This month, they’ve vomited out security fixes for the usual suspects — Windows, Office, Edge, and all the other digital landfill they call software. Nineteen “critical” vulnerabilities, meaning yet again they’ve found new and exciting ways for your systems to be mercilessly sodomized if you don’t patch in time.

Of course, there are also the “important” patches — Microsoft-speak for “If you don’t patch this, your servers will explode next Tuesday, but hey, we’re too bored to call it critical.” And naturally, they’ve helpfully supplied zero-day fixes because, once again, some bright spark was already poking holes in Windows faster than Redmond could plug them.

Oh, and Patch Tuesday just wouldn’t be complete without the unsupported systems bit. You know, for all the ancient Windows boxes still running in some corner of a dusty data center because some vendor’s 2003-era crapware refuses to die. Tough luck, you’ve still got to duct-tape your environment together while management wonders why IT “always needs downtime.”

So, grab your coffee, fire up the WSUS, and prepare for another soul-crushing evening of “testing” updates that were rushed out during Microsoft’s annual “Let’s Pretend QA Exists” festival. Maybe, just maybe, your systems won’t keel over this time. But don’t worry, January’s fiasco is only a few weeks away.

Reminds me of the time some idiot boss told me patching was “optional” because “it breaks things.” Yeah, it broke his damn face when ransomware turned the finance server into a glorified paperweight. Some people only learn through pain — and guess who had to fix that disaster? Yours truly.
