How to Disable Windows 11 Defender: Temporary and Permanent

Microsoft Defender Antivirus is the built-in security solution for Windows 11, protecting against viruses, malware, and ransomware. Users may need to disable it temporarily or permanently for various reasons, including software installation, penetration testing, performance issues, transitioning to third-party antivirus solutions, or troubleshooting conflicts. Temporary disabling can be done through the Windows Security app, which will automatically re-enable after a restart. Permanent disabling requires changes in Group Policy, applicable only to Windows 11 Pro, Enterprise, and Education editions, and necessitates disabling Tamper Protection first. Another method for permanent disabling is installing a third-party antivirus, which automatically deactivates Defender's real-time protection. Windows 11 Home users cannot use Group Policy for permanent disabling but can still temporarily disable Defender or install a third-party antivirus. Disabling Defender exposes the system to threats, and users should ensure they have alternative protection in place. Major Windows updates may reset Defender settings, and caution is advised when modifying system settings.

Microsoft is keeping Secure Boot alive with Windows updates

Microsoft is enhancing the security of Windows devices by replacing boot-level security certificates that are nearing expiration, with this initiative integrated into regular Windows platform updates. The original Secure Boot certificates from 2011 will expire between June and October 2026, prompting Microsoft to issue new certificates in 2023, which are included in many new Windows devices sold since 2024. Older hardware will require updates to remain compliant. Devices with expired certificates will continue to operate but will enter a "degraded security state," potentially hindering future updates and causing compatibility issues. The new Secure Boot certificates rollout began with the Windows 11 KB5074109 update. Most Windows 11 users will have the new certificates installed automatically, while specialized systems may have different update protocols. Windows 10 users must enroll in Microsoft’s Extended Security Updates to receive the new certificates.

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.

Windows 11 has 1 billion users

Microsoft CEO Satya Nadella announced that Windows 11 has surpassed 1 billion monthly active users, following the end of support for Windows 10. Despite this milestone, there is significant customer dissatisfaction. Windows chief Pavan Davuluri acknowledged the need for improvements in system performance, reliability, and overall user experience. Recent updates have been problematic, with glitches reported during the first Patch Tuesday update of 2026. The integration of AI features has left some users feeling overwhelmed, while the constant upsell prompts for services like Xbox Game Pass and Microsoft 365 have been criticized as bloatware. Users have also expressed frustration over forced migrations to OneDrive, where files have been deleted without consent. Additionally, there is a notable disparity in support for home users compared to corporate users, raising concerns about Microsoft's commitment to enhancing the consumer experience.

I got so mad at Windows I downloaded this free utility app to disable all its spyware

The author experienced two Windows reinstallations on a secondary PC due to issues with a lost sign-in PIN and a Microsoft account login loop. This led to a realization about the invasive nature of Windows and consideration of switching to Linux. Instead, the author used a utility called ShutUp10++ to manage privacy settings and disable unwanted data collection features. Before using ShutUp10++, it is crucial to create a system restore point to safeguard against potential issues. ShutUp10++ consolidates various privacy settings into a user-friendly interface, categorizing options and allowing users to make informed decisions. Users can choose to apply changes to their profile or the entire PC and should export their settings to prevent Windows updates from reverting them.

Microsoft Phases Out RC4 in Kerberos to Boost Security

Microsoft is phasing out the RC4 encryption method used in Kerberos to address vulnerability CVE‑2026‑20833, which allows attackers to exploit weak encryption for offline cracking of service account passwords. The transition timeline includes an initial phase starting January 13, 2026, with new Kerberos audit events and optional registry controls to identify RC4 usage. In April 2026, domain controllers will default to AES‑SHA1, disabling fallback to RC4. By July 2026, Microsoft will remove Audit mode and enforce Enforcement mode, eliminating RC4 from the Kerberos protocol. Organizations are advised to update Active Directory Domain Controllers, monitor System event logs for new audit events, address KDCSVC events, and activate Enforcement mode to enhance security against RC4-related vulnerabilities.

Windows 11 Update KB5074109 Disrupts Modems for Select Users

Many users have experienced issues with their modems after installing the January 2026 Security Update for Windows 11 (KB5074109), which removed several legacy modem drivers, including agrsm64.sys (x64), agrsm.sys (x86), smserl64.sys (x64), and smserial.sys (x86). This removal has rendered many modems inoperable. Users have reported frustrations, with some restoring functionality by uninstalling the update. Microsoft has stated that the removal of these drivers was necessary to address security vulnerabilities, but this has not alleviated user dissatisfaction. Many users are left with limited options and are advised to uninstall the update and pause future updates while awaiting new drivers from manufacturers.

Microsoft Keeps Adding Windows Features, But Trust Keeps Eroding

Windows 11 has received mixed reviews, with users expressing dissatisfaction primarily due to unexpected changes, mandatory decisions, and problematic updates rather than performance issues. Microsoft frequently introduces new features, but these are often met with resistance due to a lack of user consent and clear communication. Recent Patch Tuesday updates have led to complications, diminishing user trust. Users desire clarity about changes, optional features, and centralized privacy controls. They seek a clearer relationship with Microsoft, which includes no advertisements in core interfaces, no mandatory features without opt-in, transparent communication, and meaningful feedback mechanisms. The bond between Microsoft and its users is strained, requiring clarity and consistency to rebuild trust.

Microsoft issues SECOND emergency out of band update for Windows 11 to address disastrous Patch Tuesday bugs

Microsoft's January 2026 Patch Tuesday updates for Windows 11 have caused significant user frustration, leading to two emergency out-of-band updates within a week to address critical issues. The latest emergency update, KB5078127, was released to fix problems that made applications like Outlook, OneDrive, and Dropbox inoperable after the January 13 updates. Initially, users were advised to uninstall the updates as a temporary fix. The first emergency update on January 17 aimed to resolve shutdown and hibernation failures for version 23H2 and issues with Remote Desktop sign-in, but it inadvertently caused further disruptions to essential applications. The Windows release health dashboard remains a key resource for users seeking updates on ongoing issues.
