For the error messages I still use the err.exe from Win7 SDK
C:\>err 0x80248007 # for hex 0x80248007 / decimal -2145091577 WU_E_DS_NODATA wuerror.h # The information requested is not in the data store. # 1 matches found for "0x80248007"
if this is not included, I parse the .h files from Win10 SDK Include folder.
The Feature Upgrades in Windows 10 are the worst thing ever. I always do the upgrade via ISO when I have time and space. WU should see that I only have 1 GB free space on the 8" tablet, so trying to download/install 1803 will fail.
Please show users how to use SetupDiag to solve issues:
it does. grab the appx link from Store via HTTP proxy, download the appx and expand the appx. now run in (like my in Windows 8.1). you only need to replace the ext.dll from 17134 SDK, the inbox dll was not working on Win7/8.
