At time of submission, the official Tech Alert (TA) [1] states:
> CrowdStrike is aware of reports of crashes on Windows hosts related to the Falcon Sensor. Symptoms include hosts experiencing a bugcheck\blue screen error related to the Falcon Sensor. Our Engineering teams are actively working to resolve this issue and there is no need to open a support ticket. Status updates will be posted below as we have more information to share, including when the issue is resolved.
This is the fix:
Current fix is to boot into safe mode and change the name of the CrowdStrike folder in c:\windows\system32\drivers\Crowdstrike
Workaround Steps:
1. Boot Windows into Safe Mode or the Windows Recovery Environment
2. Navigate to the C:\Windows\System32\drivers\CrowdStrike directory
3. Locate the file matching “C-00000291*.sys”, and delete it.
4. Boot the host normally.
It does, but it is not clear whether the thing still works. The machines we treated to this workaround boot and work ok, but appear as 'offline' in the CS host management console.
If this causes a blue screen on login/boot, it’s hard for me to see a way to deploy a fix organization-wide since it doesn’t really give time for remediation to run before the crash. I’ve never been part of a large org before; is this common & how far down does management software go? (As in can it be run before crowdstrike starts)
P.s. There is a surprisingly high number of newly created accounts posting unhelpful/repetitive comments here. Wonder what’s going on
lol am i glad that i never have such a system as that on my pc directely .
i dont use cloudstrike i know how stupid bluescreen caused by security systems are .
i use a firewall in a different and security in a different way nowadays due to blue screen problems of older firewalls/virus programs .
if in ur home u have more then one pc/tablet/laptop etc , use a small pc(for pro,s just use a server pc) as ur main Firewall carrier , and let urself or someone else with the knowledge instal that pc and make sure its connected to only ur own devices it can scan ur pcs internet traffic via ur own local network , on ur own laptoptablet , usea simpler virus scanner just in case ur not at home to scan when on vacation etc(just free one) then its better , cause if the pc carrying the firewall crashes non pc in the network is actually affected by it , only security is down , and btw Windows software is not really good in seeying such a firewall system
Can't get passed the blue screen I have tried rebooting then turning back on holding windows key and R at the same time and still nothing. any recommendations

The updates from CS are very vague at this point.

Can confirm the below stops the BSOD Loop
Go into CMD from recovery options
change to C:\Windows\System32\Drivers
Rename Crowdstrike to Crowdstrike_Fucked
Start windows
Its not great but at least that means we can get some windows back..
