KB5046696 Windows 11 24H2 LTSC hotpatch update out, no restart required

Microsoft unveiled its first hotpatch update for Windows 11 24H2 LTSC Enterprise, designated as Build 26100.2240 under KB5046696, during Ignite 2024. This update is currently in preview and includes miscellaneous security improvements to internal OS functionality. Hotpatching allows updates to be applied without requiring a system reboot or user intervention, ensuring immediate implementation. This method maintains security levels, as updates are installed automatically through Windows Update. The update provides the same level of security patching as standard monthly updates, takes effect immediately, and allows users to maintain productivity without needing to restart their devices. Additionally, Microsoft introduced checkpoint cumulative updates earlier this year to minimize update sizes and reduce download bandwidth and storage requirements.

Windows 11 24H2 makes PCs faster with reduced CPU usage for Windows Update

Windows 11 24H2 introduces enhancements to the update process, including "checkpoint cumulative updates" to reduce the size of monthly update packages and improve overall PC performance. Key improvements include: - Faster installation time: 45.6% faster on well-maintained devices and 43.6% faster on outdated devices. - Reduced restart time: 39.7% faster on well-maintained devices and 33.5% faster on outdated devices. - Lower CPU usage: 15.3% less on well-maintained devices and 25% less on outdated devices. - Smaller feature updates: Approximately 200 MB reduction in download size, with conditional app downloads for only outdated or missing apps. - Techniques used to accelerate updates include reverse and forward differentials, caching parsing results, and dynamic RAM allocation. Comparative tests showed significant advancements in update efficiency, with improvements in both installation speed and resource usage. Microsoft has also separated store app updates from core system updates for a smaller overall footprint.

Windows 11 24H2 update yoinks 8.6GB of your precious drive space and refuses to give it back – but a fix is coming

Windows 11 24H2 has a bug that creates an undeletable cache of approximately 8.63GB, which cannot be cleared using the Disk Cleanup feature. This issue is related to a new enhancement called ‘checkpoint cumulative updates’ and has persisted since the update's rollout, despite ongoing complaints from users. The reported cache size may not accurately reflect the actual space used. A potential solution is to perform a clean installation of Windows 11 24H2, but this is impractical for many users. Microsoft is aware of the bug and plans to address it in a future update.

Windows 11 24H2 hoards 8.63 GB of junk you can’t delete

Users of Windows 11 24H2 are experiencing issues with 8.63 GB of disk space occupied by "Windows Update Cleanup" that cannot be deleted. Microsoft has previously stated that Windows retains copies of all installed updates. Attempts to clear this space using the Windows Settings application or Disk Cleanup tool have been unsuccessful. The problem appears to be widespread, as noted in Microsoft's Feedback Hub, and inquiries to Microsoft about potential resolutions have gone unanswered. The issue may be related to a new update management system introduced in Windows 11 24H2, which involves checkpoint cumulative updates. Although Windows identifies these files as eligible for deletion, clean-up tools fail to remove them, and manual deletion poses risks for future updates.

Microsoft seemingly makes deleting 8.63GB impossible after Windows 11 24H2 update

Since the rollout of Windows 11 version 24H2, many users have reported issues with the Windows Update Cleanup tool, specifically an inability to delete approximately 8.63GB of previous cumulative updates. Users have attempted various methods, including Component Store cleanup and Disk Cleanup, but these have not resolved the issue. Some speculate that this may be a bug, while others suggest it could be an intentional design choice related to the new "Checkpoint Cumulative Updates" (CCU) method introduced in this version. Microsoft has acknowledged a CCU-related problem that leads to an "Operation is not supported" error message.

Microsoft is bringing back Service Packs with Windows 11, under a different name

Windows 11 users are experiencing a new update approach called "Checkpoint Cumulative Updates," which consolidates previously released patches into a single package to simplify the update process and enhance system security. These updates often exceed 700MB in size, with Arm PCs exceeding 800MB. The new system allows Microsoft to release larger updates less frequently, followed by smaller incremental updates. Historically, Service Packs served a similar purpose for earlier Windows versions, allowing users to download all prior updates in one package. However, the new updates may become mandatory, which could complicate user experience and disrupt workflows. The integration of Checkpoint Cumulative Updates aims to blend past and present strategies to improve the update experience for users.
