Quick answer
The publisher FAQ describes holding Escape while signing in to disable StartIsBack/StartAllBack functionality when an incompatible shell change causes trouble. Use this as a recovery route, then investigate the version and configuration before enabling customization again.
What matters for this task
This action is different from uninstalling the application or repairing Windows. It is intended to help regain a usable session so that you can review settings, update, or remove the tool through normal controls.
Steps to follow
- Save work before signing out when you still have access to the desktop.
- Follow the publisher’s instruction to hold Escape while logging in. Do not interpret a normal menu-close action inside an existing session as the same procedure.
- When the desktop is available, record the Windows build and installed application version and inspect the most recent change.
- Use normal configuration or uninstall controls to establish a stable baseline before attempting another customization test.
Verify the result
Confirm that the desktop is usable with the functionality disabled and test the action that previously failed. If the problem remains, consider a wider Windows issue.
Limits and rollback
Keep the modification disabled while resolving compatibility. Use Microsoft’s startup and recovery guidance if the session still cannot be accessed.
Questions about this task
Does holding Escape uninstall the app?
No. The publisher describes disabling functionality at sign-in, not removing the installation.
What if the desktop is still unavailable?
Follow Windows recovery guidance and do not assume the shell utility is the only possible cause.
