Hmm, very interesting
I have noticed that the updates have changed over the last couple of months, and have only just managed to get my W8.1 laptop updated after a lot of hassle and even more time
I also got the 8024402c update error for long enough, and finally resolved it using a link I may well have found on here, something to do with resetting the netsh proxy in the command panel, among other things....
Anyway, on a related note, I've just noticed that the dreaded "GWXConfig Manager" and "GWX Update Detector" were running in my task manager, so quickly killed them and ran the trusty GWX Control Panel which dutifully, and correctly, told me that the Windows 10 app was installed on my machine!!
the upgrade option and settings weren't enabled, but nevertheless the GWX app has somehow been installed through one of these new "bundled" updates, not good in my opinion.
Just for the record I have automatic updates turned off (on both my machines), WU service set to Manual, and I manually check and update every month, after reading the KB info & choosing which I actually want installing. Security updates I tick by default, others I check, but even so this has been sneakily bundled in with either a security or cumulative roll up update - Be Warned.....
