Error 0x80072F8F - 0x20000 is associated with running the Media Creation Tool when the system date, time, or time zone is incorrect. Set the correct date, time, and time zone, and make sure time sync is enabled.
A relevant accepted resolution for this specific Media Creation Tool scenario is that Windows 7 must have TLS 1.2 enabled to run the Media Creation Tool.
Try this order:
- Correct date and time
- Set the correct date, time, and time zone.
- Ensure time synchronization is enabled.
- Install all important Windows updates
- Make sure the PC is fully updated before trying the upgrade again.
- This includes hardware driver updates.
- Disconnect nonessential hardware
- Unplug devices such as USB drives, printers, scanners, external drives, speakers, or docking stations.
- Temporarily remove non-Microsoft antivirus
- Go to Control Panel\Programs\Programs and Features.
- Select the antivirus product and choose Uninstall.
- This can help if security software is interfering with setup.
- Remove nonessential software
- In Control Panel\Programs\Programs and Features, uninstall outdated or unnecessary apps that could block the upgrade.
- If the PC is running Windows 7
- Enable TLS 1.2 first, then run the Media Creation Tool again.
Adding RAM does not address this error code directly. The error is tied to setup prerequisites and system configuration rather than memory alone.
