Hackers are increasingly targeting the startup sequence of systems, focusing on BIOS, UEFI, and bootloaders, which allows them to bypass traditional operating system defenses. Firmware threats often evade conventional security measures, providing attackers with a persistent foothold. Notable bootkits like BlackLotus, BootHole, and EFILock exploit vulnerabilities in boot components, even those protected by Secure Boot. Attackers can embed malicious code in firmware or replace legitimate bootloaders, maintaining control through OS reinstalls and hardware replacements. Common attack vectors include compromised storage, network connections, or console inputs during boot. Malicious code can execute before security software activates, and attackers may exploit misconfigured or outdated signature databases, as well as downgrade attacks on older firmware versions. To mitigate these threats, organizations should enforce Secure Boot policies, regularly update signature databases, and monitor boot behavior for anomalies.

In August 2024, a security update aimed at improving Secure Boot disrupted dual-booting of Windows and Linux due to a vulnerability in the GRUB bootloader. This allowed malicious actors to bypass Secure Boot protections. Microsoft released a patch, KB5058385, on May 13, 2025, to resolve the issue by enhancing the Secure Boot Advanced Targeting (SBAT) system's ability to recognize legitimate Linux bootloaders, preventing them from being blocked. The patch is applicable to various versions of Windows, including Windows 11 (multiple versions) and Windows Server (multiple versions). The update will be automatically applied through Windows Update for affected installations.

Microsoft's Windows 10 and 11 include features that some users find cumbersome, such as OneDrive, which is integrated but not preferred by all users. OneDrive automatically backs up default system folders during setup and offers only 15GB of storage without a Microsoft 365 subscription. Users can disable OneDrive through Computer Configuration settings. The Widgets feature, particularly the News widget, can interrupt workflow and can be disabled via Settings. The Start menu includes recommendations that some users view as advertisements, which can be turned off in Settings. Windows also has several applications set to run at startup by default, which can slow down boot times; users can manage these through Settings or Task Manager. Additionally, Windows collects diagnostic data, which raises privacy concerns, but users can opt out by adjusting settings in Privacy & Security.

Some users of Windows 7 experienced a 30-second boot delay when using solid color desktop backgrounds shortly after its launch in October 2009. This issue arose because Windows waited for system components, including desktop icons and the background, to report readiness. If any element was absent, the operating system paused for up to 30 seconds. The problem was also linked to group policies that hid desktop icons. Microsoft addressed the glitch by November 2009. As of recent data, Windows 7's market share has decreased to 2.5 percent, and Microsoft has ceased support for the operating system.

Windows 7, launched in 2009, experienced a boot delay of 30 seconds for users who set a single-color image as their desktop background. This issue stemmed from a programming oversight where the system waited for a confirmation message that never arrived because a single-color background does not qualify as a bitmap. The delay could also occur if the “Hide desktop icons” group policy was enabled, complicating the loading process. Microsoft took several months to identify and fix the problem, releasing an update in November 2009 to resolve the issue.
