Google Chrome Bug Causes White Window Glitch on Windows 10 and 11

Windows 10 and 11 users are reporting a persistent visual glitch that places an unresponsive, empty white window in the top-left corner of the screen during startup. This obstruction blocks access to desktop icons and forces users to manually close the window or navigate around it every time they turn on their PC. Recent reports identify a specific Google Chrome background process as the likely cause, offering a concrete workaround that does not require reinstalling the browser or the operating system.

Users can disable a specific scheduled task to stop the visual obstruction

The issue stems from the GoogleUserPEH folder and a scheduled task named RunPlatformExperienceHelperOnUnlock, which are background components of Google Chrome. This task is designed to manage interactions between the browser and external components such as extensions and plugins. The glitch appears across various hardware configurations, including systems with Intel and AMD CPUs, which rules out a specific graphics driver conflict as the primary cause.

Users can eliminate the white window by disabling the RunPlatformExperienceHelperOnUnlock service in the Windows Task Scheduler. This action stops the scheduled task from launching the problematic background process during the startup sequence. The workaround targets the specific mechanism that triggers the visual error without removing Google Chrome or its core functionality from the system.

The exact scope and fundamental cause of the bug remain unconfirmed by Google or Microsoft, according to user reports. The author of the initial report could not consistently reproduce the issue to verify if disabling the service provides a stable, permanent fix across all scenarios. Evidence suggests a correlation with the GoogleUserPEH task, but the definitive root cause has not been officially established by either software vendor.

We looked at Microsoft releases Windows 11 setup and earlier while tracking Google launches. Windows users experiencing this startup glitch can now attempt the task scheduler workaround to restore normal desktop access. The solution provides a practical method to address the visual obstruction while official confirmation from the software vendors remains pending.
