(If you have a fast computer and an SSD drive the process should be quick it took me about 20 minutes from start to finish to install the feature release.)
If you are still running Windor 20H2, it’s time to move to 21H1. The first thing I do is check to see what feature release version I’m on. Mid-summer is that time of the year when it’s too hot to go outside and garden so I’m inside checking on the status of various computers and reviewing what needs to be done to keep them in a happy, healthy state.
