Cannot remove Bonjour from Windows 10 laptop

I found that aborting an iTunes install with the Acknowlegements.rtf error still leaves the partial install of iPod and iTunes folders. After using Unlocker to delete same, and rebooting, iTunes successfully installed without error. Many thanks for your assistance.

I successfully uninstalled everything except Bonjour. I still get the same error when I try to delete C:\Program Files\Bonjour. It shows Read Only access and while I am using my Administrator privileges. However, I did try to right-click Bonjour, Properties, Security tab, Advanced, and when I click Change, the "Enter the object name..." field expects something, so clicking Check Names will register and possibly allow me to change permissions. Does anyone know what object name is expected? I tried Bonjour and dns_sd.jar, but neither work.

In services.msc, Bonjour is disabled, with the path to executable listed as "C:\Program Files\Bonjour\mDNSResponder.exe". However, in Change Ownership, I would need to know the exact object name for Check Names, but Bonjour, mDSNResponder.exe, and dns_sd.jar do not register; they all return that the object name cannot be found. I also tried command line with admin rights "%PROGRAMFILES%\Bonjour\mDNSResponder.exe" -remove but also get an access denied. And I cannot cd into Bonjour to delete, rename or move it without also getting an access denied. Considering the recent articles on ransomware hacking via Bonjour, I am surprised there are no solutions. As I have a Mac mini 2018 and a PC, at least I can still function. I appreciate your continued help.

I was able to change the permissions by using the object name "COMPUTERNAME\Administrator" but still got an access denied. Then I successfully removed Bonjour using Unlocker and restarted. However, when I try to install iTunes 12.10.1.4, I get the following "Error writing file to C:\Program Files\iTunes\Acknowledgements.rtf - Verify that you have access to that directory. I have no choice but to abort the install. The security tab shows "Unable to display current owner". Should I use the above object name, or will that result in more errors?
