As you can see in my SS, I already have 7zip & Winrar installed, you just need to uncheck the CAB integration option from Winrar settings/Integration TAB, nothing needed for 7zip as &zip doesn't automatically integrate CAB format files in its system. that's it & thus, that'll work flawlessly. This SS is for your easy ref.
The link at the OP still works for me. Official 18362.1 aka 1903 MCT [Still Downloading 1809 March Refresh (17763.379) ESD's] https://forums.mydigitallife.net/th...ow-rp-19h1_release.79259/page-54#post-1515648
It means they don't want a fuss about something isn't generally available yet @armond i didn't download it
hm, it seems MS is really cautious this time around after the Oct 2018 disaster. Though, am waiting for the (official) ESD release & being a bit impatience, still, I support this rather than rushing & making another mess. Currently, it's 7.38 AM at Redmond, let's wait for the next couple of hours & see whether anything will come up by today or not.
