Those are not the same as Full ESD files. Those are called canonical UUP esd's. You can find all can UUP .esd files inside the datastore.edb.
Yep, it is not a full esd and it is canonical - there is no argument about that. When you can locate it by using the File Explorer search feature you can locate all other files associating with the UUPs though.
Well on my computer this build still has bugs:- On boot up it decided to put all my icons on the left hand side (doesn't happen all the time) so have installed desktopOK.exe to put them back if it happens again...also just crashed with a message something like "driver IRQL not less or equal"
I got the next answer from Tonec about the problem with IDM: Interestingly, the Tonec Support classifies the Insider Previews of the fast ring as "the most unstable alpha version" of Windows 10. That could simply be true! Now I've to wait what the next testings of Tonec Support will 'tell'!
that's strange I have 16251.1000 (16251_RS_Pre_Can_Ref_ESDs_UUP_Pro_enUS_x64 [Ethusiast]) and when I update with 16257.1000_Can_Ref_ESDs_UUP_Pro_enUS_x64 [Ethousiast] it keeps telling me that I have an older installation and want me to download a newer one. Spoiler At the end of the process I have the only choice to make a clean install
Push on "No thanks, I'll use the older installation files" then it uses your install media. Best you do this in offline mode
I restarted the upgrade (Ethousiast 'CAN') and this time I did not chose to check for upgrades, everything went well and now I am on 16257.1000
