Microsoft confirms that a stack of bad Windows updates is causing boot issues

Windows 11 is facing significant issues following the January Patch Tuesday, particularly with boot failures on commercial devices. These problems are linked to both the January update and a flawed December update, leading to a "UNMOUNTABLEBOOTVOLUME" Blue Screen of Death (BSOD) error. Microsoft has indicated that devices that did not successfully install the December security update are left in an improper state, which can prevent booting when subsequent updates are attempted. While Microsoft is working on a partial solution to prevent further installations that could cause boot failures, this fix will not resolve issues for devices already affected. The company is investigating the causes of these update failures and their consequences.

Your BitLocker-secured Windows PC isn’t so secure after all – unless you do this

Microsoft's BitLocker encrypts personal files on Windows hard drives to protect against unauthorized access in case of loss or theft. The BitLocker recovery key is essential for decrypting data, but Microsoft has confirmed it will comply with valid legal requests for access to these keys if they are stored in the cloud. This was highlighted during an FBI investigation in Guam, where Microsoft provided recovery keys related to a COVID unemployment fraud case. Microsoft receives about 20 requests for BitLocker keys annually, but many cannot be fulfilled if users do not store their keys in the cloud. The Guam case is the first known instance of Microsoft providing encryption keys to law enforcement, contrasting with a previous request from the FBI in 2013 that was declined. Users can choose to store their keys locally or in Microsoft's cloud, but storing them in the cloud carries risks of unauthorized access. For optimal security, it is recommended to save the recovery key on a USB stick or external drive, encrypting the file if necessary, and avoiding cloud storage. Users should check their BitLocker settings in Windows 11 or 10 to manage their recovery keys and consider removing any keys stored in the cloud.

Microsoft’s first Windows 11 update of 2026 has been a mess

Microsoft has issued two emergency fixes for issues arising from its January 2026 update for Windows 11. The first patch aimed to resolve various problems but resulted in shutdown issues for certain machines, particularly those using the Enterprise and IoT editions of Windows 11 version 23H2. In response, Microsoft released an out-of-band update to fix these shutdown problems. A week later, another out-of-band update was required to address crashes in OneDrive and Dropbox for users on Windows 11 versions 24H2 and 25H2. Additionally, Microsoft is investigating reports of boot failures linked to the January update, with some machines experiencing bluescreen errors and requiring manual recovery. This situation mirrors a previous incident where a security update was initially blamed for SSD issues, which were later attributed to firmware and motherboard BIOS problems.

For January, Patch Tuesday starts off with a bang

Users accessing Azure Virtual Desktop or Windows 365 Cloud PCs through the Windows App may experience authentication errors and credential prompt failures after installing updates KB5074109, KB5073455, or KB5073724. Microsoft is preparing an out-of-band fix and advises affected users to connect via the Remote Desktop client for Windows or the Windows App Web Client. A minor subset of users may also find the password icon missing on the Windows login screen, an issue since the August 2025 update, for which Microsoft has introduced a Known Issue Rollback for Pro and Home users, while enterprise deployments should implement an updated Group Policy. Microsoft has removed legacy Agere and Motorola soft modem drivers to address CVE-2023-31096, a security vulnerability, which will render hardware reliant on these drivers non-functional after the January updates. Additionally, certificates from 2011 used by many Windows devices will begin to expire in June and October, potentially causing boot issues or loss of access to Secure Boot security fixes for devices not updated with 2023 certificates. A new section for resolved issues has been introduced in the monthly updates, addressing challenges impacting enterprise environments.

Your Windows SSD Could Be Faster, Microsoft’s New Update Reveals Why

Microsoft introduced a native NVMe driver in Windows Server 2025 to improve SSD performance by eliminating bottlenecks associated with the SCSI translation protocol. This driver allows for direct communication between NVMe drives and Windows, resulting in substantial improvements in random IOPS and reduced CPU overhead for enterprise systems. Tech-savvy users have found a way to enable this driver on Windows 11, leading to reported increases in throughput of up to 45 percent in specific storage tests. The performance enhancements are particularly noticeable in random access workloads, although users should be cautious when modifying the Windows registry due to potential risks. Speed improvements may not be significant for average users but could benefit power users and those running IOPS-intensive applications.

Windows 11 25H2 Includes a Faster NVMe Driver Needing Manual Installation

Windows has supported the NVMe storage media protocol since Windows 8.1, but the default driver, disk.sys, may not provide optimal performance. Microsoft has introduced a new driver, nvmedisk.sys, with Windows 11 25H2 and Windows 2025, aimed at improving NVMe performance. Users can check if they are using the older driver via Device Manager. The new driver has the potential to enhance performance for compatible NVMe drives in both sequential and random workloads. However, compatibility issues exist, as not all NVMe SSDs support nvmedisk.sys, which could lead to boot problems with Windows 11. Notebookcheck has published a guide on enabling nvmedisk.sys, which involves modifying three Windows Registry values, and it is advised that users back up their data before making changes.
