Security News > 2024 > July > Microsoft confirms CrowdStrike update also hit Windows 365 PCs

Microsoft says a faulty CrowdStrike Falcon update, which caused widespread outages by crashing Windows systems worldwide, also resulted in Windows 365 Cloud PCs getting stuck in reboot loops, rendering them unusable.

"We have been made aware of an issue impacting Virtual Machines running Windows Client and Windows Server, running the CrowdStrike Falcon agent, which may encounter a bug check and get stuck in a restarting state," Microsoft said on its Service Health Status page.

For Windows devices affected by the faulty CrowdStrike update, the security firm provided instructions on rebooting Windows devices into Safe Mode or the Recovery Environment and manually removing the problematic kernel driver.

Recovery is more limited or time-consuming for Windows 365 Cloud PCs that have CrowdStrike installed.

On Thursday evening, an Azure configuration change also caused a major Microsoft 365 outage, which, according to Microsoft, prevented customers across the Central US region from accessing various Microsoft 365 apps and services.

Although Microsoft applied mitigation measures that brought most affected apps and services back online, some customers still experience issues accessing and using services like Microsoft Teams and the Microsoft 365 admin center.
