Error 30 when updating keyfile
If you don't see anything at all on screen, especially if you think the updates might have been installed completely, see our How to Fix Problems Caused by Windows Updates tutorial instead.
There are several reasons why the installation or finalization of one or more Windows updates can hang.
Please let me know if you've had success escaping a hung Windows update installation using a method I don't have included in the troubleshooting above. If updates are stuck installing on or just after Patch Tuesday (the second Tuesday of the month), see our Details on the Latest Patch Tuesday piece for more on these specific patches.
Windows 10 updates seem to get stuck much more often because Microsoft pushes those fixes out more regularly.
Or, contact the application vendor to verify that it is a valid Windows Installer patch package.
Much more rarely are they caused by a mistake on Microsoft's part regarding the update itself.
If your computer doesn't let you complete these steps, contact the person who has administrator rights to your computer to complete the Chrome update.
Check the settings for your antivirus, firewall, or parental control software.
If your computer meets the Windows system requirements above, but Chrome isn't starting or you see the error message "This computer will no longer receive Google Chrome updates because Windows XP and Windows Vista are no longer supported," you might have Chrome set to run in Windows' Compatibility Mode.
Most of the time, Windows Update does its job with little if any attention from us.
