My Windows 10 PC keeps trying to install this Flash Player security update (in a time-consuming, multiple-reboot process) and keeps failing with Error 0x800f0922. I've read that this error might have to do with the System Reserved Partition being too small, but enlarging mine to 500 MB didn't fix this. I wonder if this might be related to the fact that Flash doesn't work for me on Microsoft Edge? (That issue is discussed here.)
Can anyone help resolve this error? My computer also is failing to install KB3105213, though I don't see any error code reported on this.
