After upgrading to 19.4.0, I have lost the settings and license registrations of my Windows applications. Where can the old settings before the C:\Mac transition be found?
Thank you in advance.
Other details:
Parallels 19.4.0

Thank you. I do not wish to post a technical report containing personally identifiable information in a public forum. I can submit a support ticket later. I am trying to figure out what exactly changed that affected my App Data folder contents, and where I may be able to look for the original content. I was able to manually restore functionality by reverting to a previous system restore point.
 
I ended up unregistering Windows from the VM and creating a new VM. The number of path mismatches was simply overwhelming.
 
Same issue here - for the last week. Parallels 19.4 on a MacBook Pro M3. Windows 11 Insider build 3646 fails. I built an brand new VM from scratch. Nothing installed on it, no Insider Program and it fails (error 0x800f0845) on KB5037853 update. Given this is pristine install, I can safely rule out AV or anything in Windows causing the issues (except maybe Microsoft did something to the update installer). Seems like a Parallels issue.
 
All said and done, I am actually very happy with the end result. The new VM created with Parallels 19.4 logged me in without all the Microsoft account and telemetry crap. I also turned off all Windows telemetry that I could find. Things are way better that ever before. There seems to be a difference in how Parallel now initializes the Windows VM. My experience was definitely worth it.
