Microsoft explains why restarting Windows can shut it down more completely than actually shutting it down

The Fast Startup feature in Windows, enabled by default, allows the kernel session to remain hibernated during shutdown, which results in quicker boot times by restoring a saved state. In contrast, selecting Restart clears the kernel session entirely, performing a complete boot of Windows. The process of shutting down with Fast Startup involves closing applications, logging off, keeping the kernel loaded in memory, saving the kernel and drivers to hiberfil.sys, and powering off, while Restart closes applications, logs off, ends the kernel session, and reboots immediately without saving a kernel snapshot. Fast Startup can lead to persistent issues from previous sessions, making Restart a better option for troubleshooting. To perform a full shutdown bypassing Fast Startup, users can execute the command "shutdown /s /t 0." Microsoft advises against permanently disabling Fast Startup, as it enhances shutdown-to-boot transitions.

Windows 11’s last Secure Boot deadline is weeks away, here’s what you must do

Microsoft is continuing the rollout of Secure Boot certificate updates, with the next significant deadline on October 19, 2026, when the Microsoft Windows Production PCA 2011 certificate expires. The September 2026 Patch Tuesday update has expanded eligibility for Secure Boot certificates to more PCs classified as “high confidence.” Users may need to reboot their PCs to install these updates, and some may require firmware updates beforehand. Microsoft has confirmed that the update process will persist beyond established deadlines, and older certificates are expiring in stages, with the first two deadlines having already passed. Users should ensure they have the latest updates installed and check their Secure Boot status in Windows Security. Microsoft has assured that PCs without the newer certificates will continue to boot normally and receive standard updates while the rollout continues.

Microsoft explains how to speed up Windows 11 startup

Microsoft has advised Windows 11 users to enhance system performance by managing startup applications. Users can disable unnecessary startup apps by going to Settings, selecting Apps, and then Startup. The Task Manager provides detailed insights into startup apps, including their enabled status and a "Startup impact" rating categorized as low, medium, or high based on CPU time and disk activity. Users are cautioned to be careful when disabling high-impact apps, as some may be essential for security or system functionality. Disabling a startup app does not uninstall it, allowing for re-enabling later. Additionally, users can manually add applications to startup using specific commands in the Run dialog.

In 2011, Microsoft signed the Secure Boot certificates that still sit inside millions of Windows PCs, and the first one expires on June 24, 2026, leaving unupdated machines running normally while future boot-level revocations stop reaching them

Microsoft's Secure Boot certificates, including the Microsoft Corporation KEK CA 2011, will expire on June 24, 2026, followed by the Microsoft UEFI CA 2011 on June 27 and the Microsoft Windows Production PCA 2011 on October 19. New certificates issued in 2023 will replace these older ones. While devices will continue to operate and receive standard Windows updates, they will gradually lose access to critical security updates that protect against boot-level threats. After June 24, the ability to sign new disallowed signature database payloads with the old KEK will be lost, reducing the capacity to revoke compromised bootloaders. Users are advised to keep Windows and firmware updates current, while enterprises may face challenges managing diverse machine inventories for updates.

How to check if your PC is Secure Boot ready

Microsoft has announced enhancements to its Secure Boot technology to improve system security by ensuring only trusted software is loaded during the boot process. ASUS will integrate advanced Secure Boot capabilities into its hardware, aligning with Microsoft's security protocols. This collaboration aims to enhance device integrity and protect user data against cyber threats. The updated Secure Boot technology will help prevent the execution of malicious software during startup, and both companies seek to boost consumer confidence in their products.

Windows and Linux users: The deadline to update Secure Boot keys is near

In 2012, a novel bootkit targeting Mac OS X systems emerged, infiltrating the EFI firmware. A basic bootkit for Windows 8 also appeared, compromising the UEFI bootkit. By 2013, a more sophisticated UEFI bootkit named Dreamboat was introduced for Windows. The first documented real-world UEFI attack occurred in 2018 with the malware LoJax, linked to a Kremlin-backed hacking group. In 2020, the second known UEFI malware, MosaicRegressor, was discovered, which verified the presence of a malicious file upon each reboot. New UEFI bootkits like ESpecter, FinSpy, and MoonBounce have since emerged. In response to the threat of UEFI bootkits, Microsoft collaborated with manufacturers to implement Secure Boot, a protocol that uses cryptographic signatures to ensure the integrity of firmware during startup.

June 9 Patch Tuesday incoming as Secure Boot deadline looms

Microsoft has announced updates to Secure Boot, enhancing system security by modifying support and registry keys to streamline the boot process. These updates aim to improve the security of Windows devices by ensuring that only trusted software is loaded during startup. Collaborations with Dell and STMicroelectronics are also underway to provide tailored support and integrate advanced security features into chipsets, respectively.

Your Windows PC has a security deadline in June 2026

A Secure Boot certificate refresh is being deployed across supported Windows devices via Windows Update. The Secure Boot certificates from 2011 will begin to expire in June 2026, prompting Microsoft to introduce new 2023-dated certificates to maintain security. Most users will require minimal action if their PCs are updated, but older devices may face challenges. The current certificates include: - Microsoft Corporation KEK CA 2011: expires June 24, 2026 - Microsoft UEFI CA 2011: expires June 27, 2026 - Microsoft Windows Production PCA 2011: expires October 19, 2026 The new certificates will remain valid until 2038, with plans for post-quantum cryptography around 2030. While PCs using the 2011 certificates will continue to function, they will lose access to new security protections, making them vulnerable to emerging threats. A notable example of such a threat is the BlackLotus bootkit, which exploited vulnerabilities to bypass Secure Boot. Microsoft's rollout strategy involves a staged update process that typically takes around 48 hours and may require restarts. Users are advised to keep Windows updated and check their Secure Boot status. Known issues may arise for older PCs, systems that bypassed Windows 11 requirements, Legacy BIOS systems, and custom firmware configurations. IT teams managing devices should inventory their systems, monitor specific event IDs, test updates, and document devices that cannot be updated.

Windows Secure Boot certificates start expiring June 24

Windows Secure Boot is a feature of the Unified Extensible Firmware Interface (UEFI) specification that enhances system security by ensuring only trusted software is loaded during the startup sequence. It verifies the digital signatures of boot components to protect against malicious software and unauthorized access. Key aspects include enhanced security by preventing untrusted code execution, compatibility with various hardware and software configurations, and user control over Secure Boot settings for customization.
