Hi @JustinMicheal-7973,
"The keys before deletion appeared to point to a location on the C: drive, after deletion and recreated they point at a HTTP address." It seems the update path is set to local.
How did you install the Office? Did you use Office Deployment Tool run the configuration file?
If yes, I suggest you check if the configuration file set the UpdatePath attribute, you can modify the file to default UpdatePath and refer to this support article:
https://learn.microsoft.com/en-us/deployoffice/office-deployment-tool-configuration-options#updates-element
After setting to default path, if you install with ODT and configuration file next time, the Office will update without problem.
