Hello Владимир Г.,
Thanks for reaching Microsoft Community. We're sorry to hear about this issue on your device.
In this case, please try checking your keyboard if there is a stuck key (especially the Windows logo). If there's not, then this might be due to software conflict. Follow these methods first and see if issue persists or not:
Force a shut down and restart your Surface
- Press and hold down the power button until your Surface shuts down and restarts and you see the Windows logo screen (about 20 seconds), then release the power button.
Run the Surface Diagnostic Toolkit
- In the search box on the taskbar, type Surface Diagnostic Toolkit, then select it in the list of results.
If it's not already installed, you can download it from the Microsoft Store. - Follow the on-screen instructions in the Surface Diagnostic Toolkit.
Turn Off Sticky Keys
- Open Settings > Accessibility. Select Keyboard under Interaction.
- Click on the toggle next to Sticky keys to turn off feature.
Let us know how it goes by simply responding on this thread.
