Yesterday I bought a Lenovo Yoga 920 from Best Buy. It was an open box unit. I did the new computer set-up with the walk thru software. It had WIndows 10 Home version 1703 installed. I tried a direct update to Windows version 1803, but it defaulted to doing an update to Windows 10 version 1709 with a series of patches. When it did so, the activation license became "invalid" and I found that it was now accessing a digital license connected to my Microsoft account. I then successfully did an update to version 1803. It still references the digital license. Is that a problem? Why did it invalidate my Windows 10 license on a new computer? Should I bring it back to the store?
