Dear Experts,
We have volume licenses and running Windows Education and Windows Pro Education on our clients' machines. I noticed a gap that some of the PCs will be prompted for feature update to version 21H1 but some PCs, even after checking for updates several times, there is no such option so the clients cannot go ahead with upgrading.
Any idea why this happened? And is there anyway that we can have everyone's PC displaying this Feature update option so they can upgrade on demand?
Many thanks in advance.
