Provide Read Permission to a folder in C:\ for all domain users, using Group Policy

In Windows, granting a domain user read permission to the C drive involves adjusting the permissions on the root of the C drive. Please note that modifying permissions on critical system directories like the root of the C drive can have significant security implications, and it's essential to be cautious when making such changes.

Steps:-

1.  Click on Start -> Go to Administrative Tools -> Click on Group Policy Management

2.       Group Policy Console Opens, Create a new Group Policy Object.

Right Click on Domain Name & Select on “Create a GPO in the domain...”

3.       Name the GPO.

4.       Right click on the newly created GPO and select Edit.

5.       Group Policy Management Editor opens & Go to File System (path Computer Configuration\Policies\Windows Settings\Security Settings\File System)

6.       Right Click on File System & Click on Add File.

7.       Browse to C:\TEMP(Before this Create a folder in C drive naming TEMP)

8.       Click on Add

9.       Enter Domain Users name in the object name & click OK

10.   Provide Read only access for Domain Users.

11.   Click OK.

12.   Update the Group Policy.

Now, Every Deployed machine will have read access to C:\TEMP for Domain Users.

After following these steps, the specified domain user should have read access to the C drive. Keep in mind that this will apply to the root of the C drive and to any subfolders or files. If you don't need to provide read access to specific folders or files within the C drive, you'll need to select the option "Do not allow permissions on this file or folder to be replaced". 

Note - Granting read access to the entire C drive might not be recommended for security reasons, and it's typically better to grant access to specific folders or use more advanced security configurations based on your organization's needs.
