When I try to download any app from the Windows Store, after the "Starting download" stage, it says "Error, see details". Between the 2, it says "Acquiring license" for a tenth of a second. If I click on "Error, see details" it says "Turn on Windows Update so store can show you the stuff that works the best on your device" and the erro rcode is 0x80070422
I tried enabling and disabling Windows Update in services.msc, enabling and disabling BITS in services.msc, reseted the store cache and other fixes I found online.
I installed Windows in March 2016, since then the only hardware change that would affect windows was going to a motherboard with a different chipset, but apps still worked for a while. Downloading apps works fine on my other PC, with the same Microsoft account.
Any ideas on how to fix this?
