For the past few months I’ve been running the latest Insider preview releases of Windows 11 on my main PC. In preparation for the version 22H2 feature update, which was released in October, I moved to the Release Preview channel. Because those versions have already been through testing by larger groups in the Dev and Beta channels, that’s a fairly low-risk strategy. But it’s not without occasional hiccups.
Recently, I ran into one of those annoying low-grade bugs that are inevitable when you live on the leading edge. Windows Update told me a cumulative update was available for my PC. But every time I tried to install it, the update failed with a cryptic error code: 0x800f0990.
