Thanks, I'll try that as soon as possible.

If you mean how to deactivate the license, you should use this guide: https://support.stardock.com/space/SHC/1260191763/How+to+review+and+manage+your+current+activations.

But, if you mean, Start11 still running, while uninstalling, not sure how IOBit Uninstaller did the uninstall. But, it should not be running before uninstall is done. It is important to reboot your system after the uninstall.

Thank you,

Thanks for the update. Just to share, this issue doesn’t appear on my Windows 11 25H2 system, and I haven’t seen similar reports from other users so far.

If you’d like to try again, you might consider installing it in a Windows Sandbox to see if the issue persists in a clean environment. Here’s a guide that walks you through the setup: https://support.stardock.com/space/SHC/1416855562/Testing+Start+in+Sandbox.

Thank you,

Reconsidering, I will not test your Sandbox.

What would it reveal? That my system is not compatible with Start 11? Ok. The reason why? No! So, it's not a solution.

As I already wrote, Start 11 worked fine with the same system until I upgraded to the 2.56 build. The problem thus resides in this build!

There is something I don't like.  Too often, we receive the same easy kind of answers from helpdesks:

• you are the only/first one complaining or reporting this
• this must be the fault of another soft present on your system
• blame it on Microsoft
• etc.

I don't know how many people use Start 11 but it's not possible I"m the only one concerned.

I know you're a volunteer and not part of Stardock so, I don't blame you personnaly. I appreciated your help!

But I'll wait for the next upgrade.

Do you actually understand what Windows Sandbox mean? Here a short description on What Windows sandbox actually are:

Windows Sandbox is a lightweight, isolated virtual environment included in Windows 10 and 11 (Pro and Enterprise editions). It creates a clean, temporary Windows installation that runs separately from your main system.

Benefits of testing software in Windows Sandbox:

• Fresh baseline: Lets you see how software behaves on a clean Windows setup, free from other apps or settings that might affect performance.

• Isolation: Changes made inside the sandbox don’t affect your main system.

• Automatic cleanup: Everything is deleted when you close the sandbox, returning it to a fresh state next time.

• Convenience: Quick to start and requires no extra setup like a full virtual machine.

In short, Windows Sandbox provides a simple, disposable environment for comparing how software runs on a clean Windows system.

This is the reason why we encourage user to test in a Windows Sandbox. If it still appear while in the Sandbox, than perhaps its hardware related issue. But, if it is not, that show it something in your current main Windows Environment conflicting with Start11.

Please reconsider,

Thank you,

I'm well aware of the Sandbox meaning. I'm not exactly a beginner since I use Windows from version 1, 30 years ago.

I've used all Windows versions. And I don't use other programs interacting with the taskbar. Or even Windows tweakers!

I also use Fences and Start from the first versions.

So, as already said, I'll wait for an update correcting all bugs.

Thanks again!
