Vista - Vista & virtualization

Hi

As I understand it, Microsoft has introduced 'virtualization' into
Vista to prevent users from writing data to 'sensitive' (i.e. HKLM)
parts of the registry. Instead they want developers to ensure that they
write to 'safe' locations (i.e. HKCU). My problem is this; our
application shares a number of global settings with all other system
users. So for example, on WinXP if 'user a' makes a change to our
application, all other users will see the same change when they login.
With Windows Vista, when 'user a' makes a change, it gets stored in
the 'virtual store' and none of the other user get to see it. Is
there anyway to work around this?

Thanks
Eddie.

Hi,

Just to follow up. It seems that the only way to ensure that an
application can write to all parts of the registry is to run under that
Admin account. You can do this by using the following manifest file:

<application />
<entryPoint>
<assemblyIdentity name="WindowsApplication1" version="1.0.0.0"
language="neutral" processorArchitecture="msil" />
<commandLine file="WindowsApplication1.exe" parameters="" />
</entryPoint>
<trustInfo>
<security>
<requestedPrivileges>
<requestedExecutionLevel level="requireAdministrator"
uiAccess="false"/>
</requestedPrivileges>
<applicationRequestMinimum>
<PermissionSet class="System.Security.PermissionSet"
version="1" Unrestricted="true" ID="Custom" SameSite="site" />
<defaultAssemblyRequest permissionSetReference="Custom" />
</applicationRequestMinimum>
</security>
</trustInfo>
</asmv1:assembly>

The problem I have is that this manifest will only work with C#
applications. My "Hello World" win32 application seems to just ignore
the manifest file. Can anybody help me? Is there any know issues with
Win32 apps and manifest files?

Thanks
Eddie
