The recent IT outage wasn’t just bad for CrowdStrike, but also a wake-up call for Microsoft. To avoid such instances in the future, Microsoft could take some serious steps, as it is evaluating blocking third-party security software from accessing the Windows Kernel, according to a blog post by John Cable, VP of program management for Windows servicing and delivery.
If this change were to be put in place, the restriction would imitate Apple’s 2020 move, which limited third-party software from accessing its core OS. The change was brought to macOS Big Sur, making sure that every system partition that contains the core OS is cryptographically verified, down to every last file. The goal is to curb third-party entities that could melt down the whole system.

Microsoft Previously Tried It With Windows Vista
But this change isn’t easy to pull off. The company tried doing the exact same thing in 2006 with Windows Vista, curbing third parties from having Kernel access. However, the plan failed due to resistance from EU regulators and complaints from cybersecurity vendors.
In the blog post, John Cable states, “Examples of innovation include the recently announced VBS enclaves, which provide an isolated compute environment that does not require kernel mode drivers to be tamper resistant, and the Microsoft Azure Attestation service, which can help determine boot path security posture.”
In theory, by preventing security software from accessing the kernel, Windows would never again experience a worldwide outage that happened recently, causing 8.5 million PCs to crash due to the CrowdStrike bug. The downside is that preventing kernel access would also mean that the security software would not be able to monitor for any potential threats. After all, moving in this direction doesn’t mean that other types of attacks are impossible.
Microsoft did not confirm that this is the path it will take from now. But this blog post certainly threw the idea in the air. There could be a stronger incentive to consider locking down Windows now that the wreckage of the situation is evident.

Microsoft China Bans Android, Forces Shift To iPhones
Microsoft in China has banned Android and, as a consequence, the company staff will soon be required to make a shift to iPhones. Microsoft employees in the country have been notified to make the shift from Android smartphones to iPhones by September 2024, as per a report from Bloomberg.
This was reportedly announced in an internal memo sent out to the employees by Microsoft China. The same memo has been sent to employees at the Microsoft Hong Kong office.
According to the report, the employees have been told that anybody using an Android smartphone, including phones from Chinese companies like Xiaomi or Huawei, will be given an iPhone 15 by the company. The company is reportedly creating dedicated points in its facility in the country where staff members can go to collect their iPhones.
