Hi @Connor. yes I was through all of that initially. What I’m actually after is an older rollup. What I’d ideally like to do is bring my RT installation up to a December 2017 timeline. Past that, many updates degrade performance significantly, including the Spectre and Meltdown updates. I want to avoid those, but now all I can get is the November 2018 rollup.
In an ideal world, I’d update the OS to December 2017, and update IE 11 and the integrated Flash to current, but I don’t think RT allows for that.
