14 DAY TRIAL // Microsoft has partially resolved a bug in Windows 10 May 2019 Update that blocked the upgrade when external USB devices or memory cards are connected to the computer.
This is an issue that was acknowledged by Microsoft at a time when the May update was still in testing as part of the Windows Insider program, but also impacted the first public build of version 1903.
As per the software giant, the process of Windows 10 May 2019 Update could fail with error “This PC can’t be upgraded to Windows 10” because of inappropriate reassignment during installation.
Work in progress on full fix
The bug was partially resolved on June 11 when Microsoft released new cumulative updates for Windows 10, and while the upgrade to version 1903 should now run smoother on some devices, the software giant says you should still remove unnecessary USB devices when installing the May update.
“This issue has been partially resolved but to ensure seamless update experience, the safeguard hold is still in place. In the short term, we recommend you do the following workaround to update to Windows 10, version 1903. Remove all external media, such as USB devices and SD cards, from your computer and restart installation of the Windows 10, version 1903 feature update. The update should then proceed normally,” the software giant says.
Microsoft adds that it’s still working on a full fix, and it should be rolled out in an upcoming update.
Windows 10 May 2019 Update is being pushed to devices in stages via Windows Update. However, all Windows 10 users can now manually check for updates to begin the download of the May update, while those who want to force the upgrade and skip any blocks that could exist on their devices can turn to the Media Creation Tool.
