How to use

The code below is a simple depiction of how to use it. We'll add more full code examples as they become available.

var cancellationToken = default(CancellationToken);

var inputDirectoryPath = Path.Combine(
    Environment.GetFolderPath(Environment.SpecialFolder.ProgramFilesX86),
    @"Microsoft Group Policy\Windows 11 October 2023 Update (23H2)\PolicyDefinitions");

var catalog = default(PolicyDefinitionCatalogInfo);
if (Directory.Exists(inputDirectoryPath))
    catalog = await GroupPolicy.GetCatalogAsync(inputDirectoryPath, cancellationToken);
else
    catalog = await GroupPolicy.GetCatalogFromSystemAsync(cancellationToken);

using var context = new GroupPolicyContext();
await context.ExecuteAsync(() =>
{
    var subjectGuid = Guid.NewGuid();
    if (!catalog.TryGetPolicyDefinitionByPrefix("inetres", out var inetres) || inetres == null)
        return Task.CompletedTask;

    var ieFontSizePolicy = inetres.UserPolicies.FirstOrDefault(x => x.Name == "FontSize");
    if (ieFontSizePolicy == null)
        return Task.CompletedTask;

    Debug.WriteLine(GroupPolicy.GetGroupSecurityIdentifiersOfCurrentUser());
    Debug.WriteLine(GroupPolicy.IsGroupPolicyServiceRunning());
    Debug.WriteLine(GroupPolicy.IsGroupPolicyServiceConfiguredCorrectly());

    if (ieFontSizePolicy.Elements[0].Type == PolicyElementType.Enumeration)
    {
        Debug.WriteLine(((PolicyEnumerationElementInfo)ieFontSizePolicy.Elements[0]));
    }

    Debug.WriteLine(ieFontSizePolicy.GetElementValue("element_id", null));

    if (GroupPolicy.IsCurrentUserAdministrator())
    {
        var userOrGroupSid = default(string); // GroupPolicy.GetCurrentUserSecurityIdentifier();
        Debug.WriteLine(ieFontSizePolicy.ToString());
        Debug.WriteLine(ieFontSizePolicy.GetElementValue("FontSizeDefault", userOrGroupSid));
        Debug.WriteLine(ieFontSizePolicy.GetElementEnumIds("FontSizeDefault"));

        Debug.WriteLine("Changing IE Font Size Policy...");

        var modResults = ieFontSizePolicy.EnablePolicy(subjectGuid, userOrGroupSid);
        Debug.WriteLine($"Total {modResults.Count} registry item(s) have been processed.");

        Debug.WriteLine("Refreshing pending policies...");
        GroupPolicy.RefreshPolicy();

        Debug.WriteLine($"Current IE Font Size Policy: {ieFontSizePolicy.QueryPolicyStatus(userOrGroupSid)}");
    }
    else
        Debug.WriteLine("Cannot change the policy because you don't have Administrator privilege.");

    return Task.CompletedTask;
}, cancellationToken: cancellationToken);
