showed as failed to update in update history

tried again

failed to update dissapeared from update history

But when i ran check for updates it says i am up to date

on checking my build is 19045.7058

so has kb5078885 installed or not

Answer 1

KB5078885 is installed.

Evidence from the information provided:

• The OS build after the update attempt is 19045.7058.
• That build number corresponds to a cumulative update that includes KB5078885.
• Windows Update now reports “You’re up to date,” and the failed entry for KB5078885 has disappeared from Update history, which is consistent with a later successful installation.

To double‑check on the device:

1. Open Start > Settings > Update & Security > Windows Update > View update history and review the list of Quality Updates.
2. If needed, also check Control Panel > Programs > Programs and Features > Installed Updates for CBS‑based entries.

If the build is 19045.7058 and Windows Update reports no pending updates, the security content from KB5078885 is already applied.

Answer 2

Win10安装2026-03累积更新KB5078885后，在更新历史可见安装成功；然后系统会再次推送KB5078885，如果此时重复安装，会安装失败，在更新历史可见安装失败。目前的解决方法是：保持Windows更新页面状态为“需要重启-正在等待重启”，然后通过 控制面板-程序-程序和功能-已安装更新 找到KB5078885卸载并重启，此时KB5078885应卸载并重装完成，在Windows更新页面可见“你使用的是最新版本”，最后暂停更新30天，等待2026-04累积更新的修复。
