Before attempting to update my SP6 to Win10 ver. 1903, I removed my SD card. No other devices were attached to the SP6 either. However, the update failed. I did not write down the error code, and now the update attempt is no longer shown in the update history so I can't find out what that error code was. I've been waiting for a couple of weeks now for Windows Update to offer again to install 1903, but so far it has not. Should I continue to wait for the update to be offered again, or should I download the update from MS and do it myself?
