Windows 10 and 11 users have recently been encountering an annoying bug that prevents the program from starting up. A blank white window appears in the corner of the screen, blocking any interaction. This recurring problem seems to be linked to Google Chrome, which has surprised many.
While awaiting an official fix, a temporary solution is already circulating. It involves disabling a specific task in the Windows Task Scheduler. Far from perfect, this workaround has nonetheless provided relief to several affected PCs.
Let’s discover together what causes this bug and the method to get rid of it quickly, so we can get back to a smooth and trouble-free start.
Why is this white window blocking startup under Windows 10 and 11?
Several users report a small white window that appears as soon as they log in. It appears in the top left corner of the screen, without any message or indication. There’s no need to click; it simply interferes with the user experience.
The issue affects both Windows 10 and Windows 11 machines, even the most recent models. Despite standard troubleshooting steps (disabling startup programs, clearing memory), the window persists.
This graphical anomaly is related to a Google Chrome task: RunPlatformExperienceHelperOnUnlock, saved in the GoogleUserPEH folder of the Task Scheduler. This component activates on unlock to manage extensions or updates, but apparently, it’s getting confused.
What can be done to get around this annoying bug on Windows?
The most reliable method currently is to disable this particular task in the Task Scheduler.
Here are the steps to follow:
- Open Task Scheduler via the Start menu or by typing “taskschd.msc”.
- In the left column, expand the GoogleUserPEH folder.
- Spot the task RunPlatformExperienceHelperOnUnlock.
- Right-click on it and select Disable.
Once the stain is neutralized, the white rectangle should no longer appear. It’s not a cure-all, but it works for many.
If you prefer, you can also wait patiently for Microsoft to release an official patch. This approach is particularly useful for users who want to avoid manual modifications.
A bug that reveals the flaws in the Microsoft-Google ecosystem
This type of problem highlights the complexity of interactions between operating systems and third-party applications. A popular browser, such as Google Chrome, can influence startup even if it is not directly a Windows component.
Users, often left helpless, find their machines blocked by a third-party component that installs itself without warning. This highlights the limitations of a system where transparency is sorely lacking.
To better understand and troubleshoot this type of situation, don’t hesitate to consult specialized resources that explain Windows startup problems in detail.
Other tips to avoid startup problems in Windows 10 and 11
The white rectangle bug is not an isolated incident among all the Windows startup problems. A few simple steps often prevent the worst issues:
- Keep your system up to date, especially with security updates.
- Control which programs launch at startup and disable unnecessary ones.
- Perform regular antivirus scans.
- Clean up temporary files and defragment the disk.
- Use diagnostic tools such as the Task Scheduler or Task Manager to monitor activities.
These simple precautions significantly reduce the risk of blocking bugs.
When an update can turn into a nightmare
Problems like this are reminiscent of Microsoft’s bad update streaks. Some releases cause black screens, freezes, or sudden slowdowns for thousands of users.
If you are affected by this mishap, it is advisable to adopt a strict update management strategy, so as not to suffer these setbacks unprepared.
For example, the recent Windows 11 26H2 beta promises better control over updates, which is already a significant improvement. To prepare for this, read the expert advice on the integration of this version.
What causes the white window to appear at startup?
It is a scheduled task linked to Google Chrome called RunPlatformExperienceHelperOnUnlock that triggers this empty window when the Windows session is unlocked.
Can I just ignore this blank window?
Yes, if it doesn’t interfere too much with your use. It disappears on its own after a few seconds, but some people prefer to delete it to avoid further inconvenience.
How do I access the Task Scheduler in Windows?
Type taskschd.msc in the search bar or search for Task Scheduler in the Start menu.
Is this method compatible with all versions of Windows 10 and 11?
It has been successfully tested on several recent versions of Windows 10 and 11, but results may vary depending on the configurations.
Is there an official solution from Microsoft?
Not officially yet, but a patch is expected. In the meantime, this temporary solution is the most reliable.
