CrowdStrike 's latest update has led to critical issues for many Windows users worldwide, while outages are also affecting Microsoft 365 and Azure services in US regions.
Problematic CrowdStrike update
An update for a CrowdStrike productcaused problems and outages on many computers running Windows.
According to reports from Windows 10, the update led to crashes, Blue Screen of Death (BSOD) and an inability to restart.
"We are seeing Org BSODs caused by csagent.sys and it is taking down critical services. I will open a ticket, but this issue is a big deal," one user wrote

BSOD usually occurs during system startup, preventing affected computers from booting properly.
The forums report that Crowdstrike has issued an advisory with a URL that includes the text “ Tech-Alert-Windows-crashes-related-to-Falcon-Sensor-2024-07-19 .” However, this is behind a regwall that only customers can access
According to the advisory, CrowdStrike reportedly says it has been notified of outages on Windows. Basically, blue screen errors appear related to the Falcon Sensor.
Reports of outages have come from multiple countries, including Australia, New Zealand, India, and Japan. So far, DownDetector is indicating an outbreak of problems across a number of platforms and businesses in the US, including Amazon Web Services , Instagram, eBay, Visa, ADT, and PlentyOfFish.
CrowdStrike is working to resolve the issue
Falcon Sensor is an agent that, according to CrowdStrike, “blocks attacks on your systems while collecting and recording activity to quickly detect threats.” Right now, however, the Falcon Sensor itself appears to be the problem.

For this reason, users are advised to avoid installing the latest update until a solution is found. CrowdStrike also suggests booting into safe mode and uninstalling the problematic update.
US: Microsoft 365 and Azure also on hiatus
Users in some regions of the US are also experiencing issues and outages in Microsoft 365 and Azure services . This outage has led to widespread service outages, affecting businesses and individuals who rely on Microsoft's cloud services
The outage began on July 18, affecting many services, including storage cloud , and various enterprise applications.
Microsoft is investigating the cause of the outage and working to restore services.
While some services may now be operational, Office applications are still experiencing issues.
Preliminary reports suggest that the issue may be related to changes in network, but the investigation needs to be completed. Users are advised to monitor official Microsoft channels for updates on the status and possible solutions.
The above outages in Windows (due to CrowdStrike update) and Microsoft 365/Azure highlight the challenges and vulnerabilities in the cyber world and at the same time create many problems.

For example, the consequences for Microsoft 365 and Azure users were multifaceted and affected various aspects of their daily work. First of all, users were unable to access email, which created significant problems in communicating and managing their professional obligations. In addition, the outage affected file storage and sharing services. This resulted in the inability to access critical documents and files, delaying the completion of projects and the exchange of information between team members.
Such outages raise concerns about the reliability and security of services. Users may begin to question the companies' ability to provide stable and secure services, which may affect their trust and decision to continue using Microsoft services in the future.
