Yesterday, I was on-line with a major file server, possibly in Canada, downloading a ~1 TB file, when I got the BSOD.
My PC's do NOT BSOD, so that really threw me for a loop!!!
I immediately shut down my PC, changed to a different SSD, with Windows 11/Pro/64 on it, reconnected to the Server and finally got my download file. No more BSOD's.

Today, I checked my SSD's for the \CloudStrike\ directory, and I don't have it!
So, something must have downloaded from the File Server that caused my PC to BSOD.
That's the best explanation that I've got.

May it never happen again!

Rust is the future, period. C and C++ are becoming outdated.

It's not just Rust. Rather, it's both Java and Rust. Right now, as a matter of fact Google also are moving away from C/C++ in favor of Java and Rust. A lot of people still don't have any idea what Java is, though. They usually think it's mainly just another programming language. The reality is that Java covers a very wide range of technologies, based heavily on an exceptionally long list of proven standards, yet constantly continuing to evolve, and, the Java language (Java lang) represents less than a few percent of what it is. Spring Boot has become pretty hot as an example. (Just don't expect it to also be hot on any Windows related forum...

I have never heard about Rust until what I quoted earlier. Interesting though.

Updates on the network should be never applied simultaneously.

I've always thought that wasn't a good way of doing things. Should be able to do it in blocks for real world testing first.

Its very rare for an update to break Windows. They're tested throughly before they're deployed.

I have to ask. Are you being serious?

Almighty1 · Jul 21, 2024

It could be it's done on purpose too since remember a bug is a feature and a feature is a bug so new versions will be out later. If they released everything bug free, they will not need new updates. And this is free publicity even though it might be bad.

Of course, this literally happens at least once a year from various AV vendors.

LOL, yes and when you get audited after some sort of malicious breach and say "well it's a critical box and thus we don't put an AV on it because we have to ensure it's running", that's going to be a fun conversation.

yeah I am confused. We have to meet security compliance. Maybe my parent company making those decisions screwed up somehow but an antivirus needs to be able to update, you cannot possibly screen every single update that comes from your AV. That kinda defeats the purpose of the protection if you delay it.

This does not happen once a year? Your telling me antivirus companies causing massive failures like this every single year? Where?

I agree that updates on the network should not be applied across the board. But I have never heard of someone stagnating their antivirus updates across the company.

I am not sure how that would even work. Antivirus updates more often a day than the time you would need to test them all. They are also cloud based streaming updates.....

If your talking program versions updates, that is another story. But that wasn't what happened here.

From what I understand, this was a driver update that was not included in the patch management and was pushed out to all machines via cloudstrike themselves. I cannot find anything or any source showing this update was able to be tested first on companies ends before pushing it out. It seems it was instantaneous with no approval.

If you use crowdstrike and were able to deny this "update" I would love to know.

"She was not even allowed to change her wallpaper"

Reminds me of a Windows 3x-era policy. Because before Windows 95, if the wallpaper got changed, then it will get changed for all other accounts.

I distinctly remember that before all or many PCs got upgraded to Windows 95, that was like a crime!
