KB5058499 fails to install
on Windows

I’ve been trying to install the KB5058499 update on my Windows 11 PC, but it keeps failing with an error message at different stages. Any idea what I can do to make it install?

KB5058499, not installing issue is becoming the bane of Windows 11 users eagerly awaiting to install this optional preview update, which was distributed on May 28, 2025, for version 24H2 (OS Build 26100.4202). This update introduces features like Cross Device Resume, enhanced taskbar policies through Microsoft Intune, and solutions to unresponsive games and slow initial boot screens, along with Input Service memory leak fixes, as indicated in the recent updates.

A KB number, for example, KB5058499, is Microsoft's nomenclature for update packages where "KB" means Knowledge Base and is linked with support articles, and their update cycle comprises mandatory Patch Tuesday releases every other second Tuesday of the month and optional previews like this one later on in the cycle to test new features.

When KB5058499 fails to install, users don't notice these improvements, which might leave systems with ongoing performance issues like crashes of games or memory leaks, possibly affecting productivity and gaming sessions. Failed installs can also lead to update loops or system corruption states, making future updates hard and possibly jeopardizing data integrity if not addressed promptly. Errors like 0x800f0922 or 0x80070306 have been reported by some users, generally linked to insufficient space available on the EFI partition or service disruptions.

KB5058499 won't install error can be caused by numerous reasons, typically due to preview mode. A buggy update cache can lead to the process being hung, and cache clearing allows for a fresh attempt to install. Low disk space, especially on the EFI partition, can block the update, and the need for space shifting or resizing is required.

Intrusive network or antivirus software interaction can disrupt downloads, and having a stable connection or disabling security software temporarily might help. System files that are corrupted or misconfigured can also be the cause, and they need to be repaired or reset to compatibility.
