The terrifying result of having ABI compatibility with the first commercially successful system of its kind from the '80s. Granted, they aren't doing themselves any favours with their new straight-jacket style application ABI.

You are trotting out the same tired line without reading the article carefully? ;)

This is a regression. The article shows it worked fine up to Windows 7.

Then why are you commenting? Kind of a crappy attitude you have there.

not really, I was kinda expecting the post would also contain interactions with Microsoft, leading to the resolution of the bug in update XX. The post kinda left me unsatisfied.

You can fix those problems by writing a post that would contain said interactions, resolution and update.

Sure, and you're entitled to feel that way, but that doesn't make his attitude any less crappy.

How is ABI compatibility with early systems the cause of this bug? You'll note that it wasn't present in Windows 7.

I grew up on the Commodore 64 (1 Core, 1 hyper-thread :-), almost 1 MHz clock freq, almost 64 K usable RAM).

The machine was usually pretty responsive, but when I typed too quickly in my word processor it sometimes got stuck and ate a few characters. I used to think: "If computers were only fast enough so I could type without interruption...". If you'd asked me back then for a top ten list what I wished computers could do, this would certainly have been on the list.

Now, 30 years later, whenever my cursor gets stuck I like to think:

"If computers were only fast enough so I could type without interruption..."

So what now ?

Should/does the author wait getting some traction on Hacker News and hopefully be noticed by dev at Microsoft, or is there some way to provide Microsoft directly these data, skipping Tier-1 support ?

The author seem to be working at Google, so he might get some leverage from that, but what about Random Joe ? Keep enjoying the bug "forever", I guess ?

While I too am anxious to hear the outcome after Microsoft investigates the author still shared something they were interested in of which holds a value to the HN community as many of us love digging into a system and finding issues. This was the main purpose of the article.

Regardless the author may not know how critical Microsoft has classified this issue. It could be something they don't resolve for years. Since the Microsoft investigation and possible patch has no barring on the content of this article I wouldn't expect it to be held until such a time.

I'm sure we'll get a follow up on HN when or if it gets patched. Even better maybe posting this article helps get it fixed sooner :)

I was wondering what ETW is, and found in one of his other posts: ETW (Event Tracing for Windows). He seems to be one of the main contributors of https://github.com/google/UIforETW Seems to be quite useful. --- About the post: tl;dr: NtGdiCloseProcess has a system-wide global lock which is used quite often e.g. during a build of Chrome which spawns a lot of processes. This problem seems to be introduced between Windo…

I wonder if this is the same lock most win32k call takes.

It's all just trade offs. However fast or powerful your machine is, software will use as much of that resource as possible, up to the point where it occasionally interferes with input (but not too much or you'll switch to something else).
