In this comprehensive guide, I‘ll leverage my decade of experience as a Microsoft-certified IT professional to walk you through various proven solutions to fix the KB5023778 update installation on Windows 11.

A Quick Primer on Windows Updates

Before we dive into troubleshooting, let‘s briefly understand how Windows updates work:

  • Windows updates are released in cyclical batches containing bug fixes, security patches and new features.

  • They are distributed via different channels like Release Preview and General Availability.

  • Cumulative updates bundle all fixes since the last major version. Applying latest CU ensures you have all fixes.

  • Updates are downloaded in background by Windows Update (wuaueng.svc) and Background Intelligent Transfer Service (BITS).

  • Various failure points like download issues, corruption, conflicts can block updates from installing correctly.

Now let‘s look at what‘s included in the problematic KB5023778 update.

What Does the KB5023778 Update for Windows 11 Contain?

The KB5023778 update is one of the latest optional cumulative updates for Windows 11 released in September 2022.

It includes the following changes:

  • Introduces Microsoft account notifications in Start menu – Profile pictures and notifications from Outlook, Calendar, Teams etc. will start appearing for users signed in with their Microsoft account.

  • Adds a lighter search box on taskbar when it is set to a custom accent color. This improves visibility of background wallpapers.

  • Fixes issues affecting Notepad, PowerPoint slide preview, Narrator scan mode and USB printers. Improves system stability.

  • Some devices may see different visual treatments for gathering feedback.

Now let‘s analyse why you may be facing issues installing this update on your PC.

Potential Reasons for KB5023778 Update Not Installing on Windows 11

Based on my experience troubleshooting Windows update issues for clients, here are some of the common reasons you may encounter problems installing the KB5023778 update specifically:

  • Windows Update glitches – Issues like failed downloads or incomplete installations can prevent the successful update application. Server-side problems can also affect rollout.

  • Corrupted system files or pending actions – The Software Distribution folder, Catroot2 folder or other system files getting corrupted blocks installation of new updates.

  • Background Intelligent Transfer Service (BITS) problems – Since BITS handles the download of Windows updates in the background, any glitches like an stopped service can lead to issues.

  • Incorrect Windows Update settings – Having Windows Update switched off or being on a non-targeted update channel like Release Preview can block updates.

  • Old drivers or software – Outdated or incompatible drivers/software can sometimes clash with new updates leading to failed installation.

  • User Account Control issues – Windows needs elevation via UAC for installing updates. Disabled UAC can block updates.

Now I‘ll guide you through the top solutions to fix the KB5023778 not installing or downloading issue on your Windows 11 PC.
