Microsoft Paint’s RCE Fix: Still a Verification Shitshow

So here we are again: Microsoft ships a fix for a nasty little remote code execution issue in Paint, and verifying whether the bloody thing is actually patched across Windows PCs turns into the usual enterprise-grade goat rodeo. The article’s point is simple: yes, there’s a fix, but confirming it consistently across different systems is still a pain in the arse.

The problem is that Microsoft Paint is no longer just some neat little binary sitting quietly where admins can point at it and say, “There, that version.” No, that would be too sane. It’s tied up with the Microsoft Store and modern app packaging, which means the versioning and update verification process can become muddled as hell. Depending on the Windows build, deployment method, and how apps are updated in your environment, checking whether the vulnerable version has been replaced is not nearly as straightforward as it bloody should be.

In other words, security teams are expected to prove they’re protected from an RCE flaw, but the practical steps for doing that across a fleet of machines are inconsistent, annoying, and full of the sort of ambiguity that makes auditors grin and admins swear. You can’t just assume that because Windows Update ran, everything’s fine. And you can’t always rely on a neat, universally obvious indicator that Paint has been dragged out of the danger zone.

The article highlights that this is part of a larger recurring mess with Microsoft’s app servicing model: bits and pieces come from different channels, patch visibility is fragmented, and verification becomes a game of “which half-broken tool do I trust today?” It’s the kind of crap that wastes hours while management asks why it’s taking so long to confirm a fix for a tiny drawing app that should, by all rights, not be a security drama in the first bloody place.

Bottom line: the Paint RCE may be patched, but proving it across Windows PCs remains harder than it should be because Microsoft’s update and app-version plumbing is, as usual, a steaming pile of overcomplicated shit. If you’re an admin, congratulations: you now get to spend part of your week verifying a patch for Paint like it’s a mission-critical trading platform.

Anecdote time: this reminds me of the time someone asked for proof that Notepad had updated properly across a department, and by the end of it we had three reports, two conflicting version numbers, one helpdesk ticket marked “resolved” by a complete idiot, and a manager asking whether we could “just reinstall Windows to be safe.” That’s when I went for coffee and considered a career in arson. Cheers.
