Windows 11 allows users to limit RAM usage through the System Configuration tool (msconfig) for testing and troubleshooting purposes. Users can specify the maximum memory in megabytes, but there is no simple option to set a fixed amount like "4GB of RAM." Limiting RAM can degrade performance and may cause applications to become sluggish. To limit RAM, users must navigate to the Boot tab in msconfig, check the Maximum memory option, and enter the desired amount. To restore full RAM access, users need to uncheck the Maximum memory option in the same tool. On some modern systems with UEFI firmware and Secure Boot enabled, the Maximum memory setting may not be accessible, and disabling Secure Boot may be necessary to apply the limit. Disabling Secure Boot can reduce security against boot-level malware.

A modder demonstrated Windows 11 running on a vintage system with a Core 2 Quad Q6600 processor, DDR1 RAM, and an ATI Radeon HD 4650 AGP graphics card, achieving stable performance with games like Half-Life 2 and Crysis. The setup utilized an ASRock ConRoe865PE motherboard with an Intel i865PE chipset and required some "hacking interventions" for hardware compatibility, including launching the AGP 8X interface and activating H.264 video decoding. The Radeon HD 4650 AGP used Windows 7 64-bit drivers from 2012. The modder noted that Windows 11 officially supports BIOS systems via Windows 11 IoT, contributing to its stability on older hardware. The system's performance was enhanced by a Toshiba THNSNJ512GCSU solid-state drive (SSD). Additionally, another modder doubled the performance of a GeForce GTX 1650 by increasing its VRAM to 8 GB, and a different modder compressed GTA V to 2.5 GB.

Major PC manufacturers, including HP, Dell, ASUS, Lenovo, MSI, Acer, Samsung, LG, and Microsoft’s Surface division, have provided guidance on transitioning to new Secure Boot certificates as the expiration of Microsoft’s 2011 certificates approaches. The expiration will occur in three phases: Microsoft Corporation KEK CA 2011 expired on June 24, 2026; Microsoft UEFI CA 2011 expired on June 27, 2026; and Microsoft Windows Production PCA 2011 is set to expire on October 19, 2026. Microsoft has begun rolling out replacement certificates through Windows Update, contingent on OEMs providing compatible BIOS updates. ASUS offers detailed documentation for both consumer and commercial devices, confirming that most users will receive updates automatically. Lenovo provides direct download links for BIOS updates organized by product family and specifies which products will not receive updates. Dell's support article covers its entire product lineup, noting that devices with an End of Service Life before January 1, 2026, will not receive updates. HP outlines a dual-track approach for updates, with specific timelines for commercial PCs. Microsoft's Surface devices receive updates directly from Microsoft, while MSI categorizes guidance based on processor generation for its laptops. Acer emphasizes backing up the BitLocker recovery key and provides a model table for confirmed BIOS release dates. Samsung confirms that all PCs running Windows 10 or 11 will function normally post-expiration, but security updates will cease. LG has released a guide for checking BIOS updates for its PCs. To verify if a PC has the 2023 certificates, users can check the Secure Boot section in Windows Security. A green checkmark indicates successful application, while yellow or red icons indicate pending updates or incompatibility. Microsoft has pushed the certificates to all eligible devices as of June 2026.

Omores has successfully demonstrated running Windows 11 on a Core 2 Quad Q6600 with a DDR1 motherboard and an ATI Radeon HD 4650 AGP graphics card. The system is stable and capable of running modern browsers, games, and 3D benchmarks, including the demanding game Crysis. Compatibility was achieved by integrating ATI’s Windows 7 64-bit drivers from 2012. Windows 11 operates on older systems without UEFI and only ACPI 1.1, and it officially supports BIOS systems through Windows 11 IoT.

Riot Games has introduced a new feature for its Vanguard anti-cheat system called Vanguard On-Demand, which allows the kernel driver to load only when a Riot game is launched and unload upon exit. This change ends the previous practice of loading the driver at Windows start-up, which has been in place since 2020. The new mode is supported by Windows 11 25H2 and requires specific hardware configurations, including UEFI Secure Boot, TPM 2.0, Virtualization-Based Security (VBS), Hypervisor-Protected Code Integrity (HVCI), and IOMMU. Approximately 35% of players currently meet these hardware requirements, while around 3% are using incompatible systems. Riot has created a checklist called Vanguard Pre-Check to help players determine if their systems qualify. The percentage of fully secured machines is estimated to be around 34.33% and is increasing monthly. Players whose systems do not meet the criteria will need to make manual adjustments in their BIOS. Vanguard On-Demand mode will be available for players on Windows 11 starting later today. The feature is based on Microsoft’s Runtime Driver Attestation Report, which tracks driver activity since boot and helps ensure no vulnerable drivers have been loaded while Vanguard is inactive. Riot Games has required TPM 2.0 and Secure Boot on Windows 11 since 2020 and has faced criticism for these requirements. Enabling VBS and HVCI may affect frame rates and could disable older peripheral drivers due to Microsoft's vulnerable driver blocklist.

Riot Games is updating its Vanguard anti-cheat system to an "on-demand" model, which will only activate during gameplay and stop once the game ends. This change addresses concerns over Vanguard's previous persistent background operation and kernel mode access. Players must meet specific security criteria to use the new feature, including enabling pre-boot security mechanisms and Windows' native protection features. Approximately 35% of players already meet these conditions, while 3% using older hardware will not have access to the on-demand option until they upgrade. Vanguard will continue its current operation for those unable to meet the requirements. The update is influenced by advancements in Windows and PC hardware security and aims to enhance anti-cheat measures while keeping the process optional for most players.
