We couldn't install this update (0xc1420121)
I have been trying to update Windows 10 to the Version 2004. I have tried every solution I could find on the web, including attempting the upgrade from a USB thumb drive. I get different errors-- this is the most recent one. we couldn't install this update but you can try again (0xc1420121) All drivers are current Date and time is correct I stopped BitDefender permanently and did a reboot I already did the following: Windows Update Troubleshooter Stopped Windows update service and cleared Previous Windows update cache Deleted all files in: C:\Windows\SoftwareDistribution\Download Ran the SFC utility Tried the Upgrade Assistant and made the USB media. Nothing worked. Any ideas?
