As per the ANI report, in an update, Microsoft said, "Our services are still seeing continuous improvements while we continue to take mitigation actions. Multiple services are continuing to see improvements in availability as our mitigation actions progress. More details can be found within the admin centre."

Meanwhile, the Indian Computer Emergency Response Team (CERT-In) has issued an advisory, CIAD-2024-0035, addressing the severe outage impacting Microsoft Windows systems.

The CrowdStrike team has reverted the changes made in the recent update. However, according to the ANI report, if hosts are still experiencing crashes and are unable to stay online to receive the necessary channel file changes, CERT-In has recommended certain steps.

Steps to reboot a Windows host:

1. First, boot Windows into Safe Mode or the Windows Recovery Environment.

2. Next, navigate to the directory C:\Windows\System32\drivers\CrowdStrike.

3. Locate and delete the file matching the pattern "C-00000291'.sys".

4. Reboot the host normally.

Users are also advised to check for the latest updates and further instructions on the CrowdStrike support portal.

On Friday, the outage affected companies across various sectors, from airlines, banks, food chains and brokerage houses to news organizations and railway networks. The travel industry was greatly affected, causing significant delays in flights across the world, reported ANI.
