Joseph in support gave me a better answer.
Hello Patrick,
Thank you for contacting Parallels Desktop Support.
Please uninstall the latest update of Start8 from the Windows Control Panel > Programs and Features; here is a link
http://windows.microsoft.com/en-us/windows-8/uninstall-change-program you can read for steps to remove a program.
After removing Start8 you can reinstall it again by following steps on step number 2 found on this link

Do not update Start8 after reinstalling it.
Start8 is a third party application and if you prefer to use the update you need to purchase their license.
