Windows 10: Program files(x86) has wrong permissions

Dear Forum,

i am currently experiencing a security issue with my Program Files(86 that is a bit bothersome. Recently i reinstalled two machines with the help of MDT and updating goes via WSUS. All our current machines are domain joined and we are in the process of migrating to Windows Server 2019. We are currently on Windows Server 2K8R2.

I have had it with 1 user with an old configuration and 2 new freshly installed computer that from on day to the other my program files(86) folder rights and permissions are not correct. The Current owner is the Hostname\Administrators, i think thats the group, Integrity level is set on High Mandatory level, and the 3 Permissions entries that i see are, System, Administrators and Users.

I can not install 32 bit applications any more, i can't change the owner of the folder nor can i add new entries to the permissions list. I have tried to rebuild my ACL i have tried retaking ownership. but without any success.

We are deploying group policies within our organization but i am unaware that and if a group policy has the ability to rewrite and revoke folders that are protected by microsoft's Windows Resource Protection (WRP).

Any ideas for what could be causing this?. A laptop effected by this problem was reinstalled last Friday, and by today the permissions have been revoked.

Forgot to mention:

OS: Windows 10 Enterprise Version 1909 OS Build 18363.720

Hi Luca,

Thank you for posting in Microsoft Community, we appreciate your interest in Windows 10.

I understand the inconvenience you are facing with accessing the files and folders on Program file and Program file x86, we will help you with this issue.

Do let us know the following to assist you better:

• Have you logged in as an administrator?
• Is this issue specific only to the Programs file and Program file x86 folders?
  

Step 1: If you have logged-in as an administrator, I suggest you to follow the below steps to give permission for entire system, so that you can access the specific files.

• Right click on the folder and click on
  Properties.
• Click on Security tab and select the
  group\user name.

  Full control.

  OK on the Security message, if one appears.

  Administrator if you are logged in as Administrator, or click the
  Administrators group.
  
  If you want to take ownership of the contents of that folder, click to select the
  Replace owner on subcontainers and objects check box.

• 
  You may receive the following error message, where
  Folder is the name of the folder that you want to take ownership of:
  You do not have permission to read the co1ntents of directory Folder. Do you want to replace the directory permissions with permissions granting you Full Control? All permissions will be replaced if you press

Installing Jenkins outside of "Program Files (x86)" directory

I installed Jenkins server on my Surface in the "Program Files (x86)" directory. I later wanted to edit a config file to change the port, but it wouldn't let me since I didn't have permissions. Is there anything wrong with installing Jenkins server or
other programs outside of the "Program Files (x86)" directory assuming the installer permits the directory to be changed.

 

Program Files (x86) (x86)

I have folders for program files, program files (x86) and program files (x86) (x86). Believe the program files (x86) (x86) is based on loading an incompatible Lexmark printer software as the only folder within is Lexmark 3500-4500 series. Tried to delete
folder but states "action can't be completed because the folder or a file in it is open in another program. I have uninstalled all associated printer/software from system but can't seem to delete this folder. Any advise would be greatly appreciated. Thx
