Faulty Windows Update from CrowdStrike Hits Banks and Airlines Around the World
A faulty software update to enterprise computers by cybersecurity firm CrowdStrike has taken millions of computers offline, most of which are in a commercial or enterprise environment, or are Azure deployments. CrowdStrike provides periodic software and security updates to commercial PCs, enterprise PCs, and cloud instances, with a high degree of automation. The latest update reportedly breaks the Windows bootloader, causing bluescreens of death (BSODs), and if configured, invokes Windows Recovery. Enterprises tend to bulletproof the bootloaders of their client machines, and disable generic Windows Recovery tools from Microsoft, which means businesses around the world are left with large numbers of machines that will each take manual fixing. The so-called "Windows CrowdStrike BSOD deluge" has hit critical businesses such as banks, airlines, supermarket chains, and TV broadcasters. Meanwhile, sysadmins on Reddit are wishing each other a happy weekend.

Testing can only get you so far because no matter how thoroughly you do it, you will never be able to replicate every single possible machine configuration that an update may be installed on. So it's very much a question of "good enough". Except that, in some cases, it isn't - and this is one of them.
This, BTW, is another thing that the "Windows bad" horde fails to understand. The possible combinations of Linux/Mac machines and software is so much smaller and so much less complicated, precisely due to a far smaller install base. For Linux there is also the advantage that most machines are servers, so bad patches there manifest as "third party is down" to the outside world and thus no news articles; for Apple it's the fact that they only have to support machines that are less than 4 years old (M1 launched November 2020), so it would be really hard to screw up.
Crowdstrike's SNAFU seems to be affecting way more than an odd 1-2% which would be explained away by particular configurations.
How many guys do you think run Win10 on a single core system with 2GB ram?
How about a dual or quad core with 4GB?
That first one flat out doesn't exist anywhere outside of WinPE mode because it's insufferable.
That 2nd one is my Surface 3 tablet, which has never been a fun experience at any point in history.
The majority of Win10 users are probably running some 4/6/8 core chip with a bare minimum of 8GB, some GPU that is 3-16GB and gigabit ethernet.
If you think about it, that really narrows down the product stack and gives you a good idea of who and what you would expect to be running this or that.
Make some assumptions.
nobody caresthere is a significantly smaller consumer install base. If Linux someday magically becomes the lead desktop OS we can expect the same scale of security issues and threats as Windows.Suggestion to others - the hate boner for Microsoft is ridiculous here, as well as lack of understanding how things work.
This is a third party people. There's a lot of issues to discuss and blame to dole out but none of them involve MS this time around.
Crowdstrikes workaround
Workaround Steps for individual hosts:
Come on, man, I specifically said “smaller CONSUMER install base”. I was talking in this context and this context alone. I am well aware of Linux server market share.
Not to mention, a pain in the ass to grab and enter manually in each system.
I think it will be quicker but more painful due to possible data loss, to simply re image.
Such headlines are everywhere.
I dont know if CS will survive after this. Interesting option.
On another note, Poor remote users without local admin privileges.
