Persistent Update Download Bug in Windows 11 Dev Channel Frustrates Users
A recurring issue in the Windows 11 Dev channel has caught the attention of users, particularly concerning the update download process. This channel, designed for testing purposes, is not unfamiliar with bugs; however, the persistent update download bug has proven to be a thorn in the side for many users. The latest build, 26120.1542, released under KB5041872, has reignited frustrations as downloads frequently stall at 8%, accompanied by a troubling spike in CPU usage.
Users Share Their Experiences
Reports from affected users indicate that while attempting to download the latest cumulative update, their systems become sluggish, with CPU usage soaring to 100%. This phenomenon suggests that the download process is struggling to execute tasks in the background, resulting in noticeable system slowdowns and unresponsiveness.
A user on the Microsoft forum, Sujal Thakkar, expressed their concerns regarding this issue, which has garnered attention from 49 others. In their post, they detailed their experience:
I am trying to update the build Cumulative Update for Windows 11 Insider Preview (10.0.26120.1542) (KB5041872). However, whenever I attempt to download the update, it consistently gets stuck at 8%. When it reaches 8%, the CPU usage by the Windows Modules Installer spikes to 80-90%, causing the PC to become unresponsive and slow. The issue resolves after restarting the PC and pausing the update. However, the problem reappears as soon as I resume the update, making it difficult to use the PC smoothly. I have tried restarting the Windows Modules Installer and Windows update from the systems. But it still is not resolving.
Another forum participant, matGV, echoed similar frustrations with an earlier build, KB5038603. Their post, which has received 24 upvotes, highlighted the impact of the TiWorker EXE process, known as the Windows Update Trusted Installer Worker Process, on system performance:
I am experiencing an issue with the Cumulative Update for Windows 11 Insider Preview (10.0.26120.1252) (KB5038603). The download remains stuck at 8% and does not progress. Here are some additional details about my system and what I have tried so far:
- Windows Version: Windows 11 Insider Preview
- Build Number: 10.0.26120.1252
- Update Type: KB5038603
Additionally, I have noticed that the TiWorker.exe process is using a high amount of CPU, which significantly slows down my system. This also causes frequent crashes in games and applications.
