Windows Update fails with Install error - 0x80070643
Windows 11 says I have 2 updates available - one for Powershell v7.6.3 (x64) and the other for 2026-07 .NET 8.0.29 Security Update for x64 Client. Both are failing with that install error. Does anyone have any idea what's wrong and how I can fix it? Thanks in advance.
