    update error 0x80070643 applying 05-2023 update for Win10 version 21H2


    I have an older laptop that I need to update. I'm trying to catch up on updates and encounter update error 0x80070643. The update shows the download at 100% but immediately fails when trying to install.One of the first suggestions is to increase the size of the WinRE partition, but when I follow the instructions for KB5028997 I get the following error:C:\WINDOWS\system32>reagentc /infoWindows Recovery Environment Windows RE and system reset configurationInformation: Windows RE status: Enabled Windows RE location: \\?\GLOBALROOT\device\harddisk0\partition6\Recov
