### Windows version, edition, and architecture

Windows 11, version 25H2

### Describe your issue

Today my Veeam Agent for Microsoft Windows Service suddenly stopped working, see [Knowlege base](https://www.veeam.com/kb1959). Reason after all was different versions for .NET runtimes:
```
C:\>dotnet --list-runtimes
Microsoft.AspNetCore.App 8.0.26 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.NETCore.App 6.0.36 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 8.0.25 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 9.0.15 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.WindowsDesktop.App 6.0.36 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]
Microsoft.WindowsDesktop.App 8.0.25 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]
```
UniGetUI had no current versions 8.0.26 for `Microsoft.NETCore.App` and `Microsoft.WindowsDesktop.App` available.
BUT - had previously updated `Microsoft.AspNetCore.App` to version 8.0.26. And this made Veeam fail - it needs all components having the same version.
So my request is to only update all three runtimes at the same time. Postponing individual updates until all three runtimes are available with the same version.
