UAC - File Virtualization (VirtualStore missing)

I’m currently troubleshooting a problem with UAC - File Virtualization in

Vista SP1. File Virtualization is not working in Vista and is breaking some

applications that previously tested good. The difference with this build is

that the C:\User folder has now been relocated to the D:\User. It now seems

that Vista is not creating the VirtualStore Folder & and respective

sub-folders under %LocalAppData% (which is pointing to the correct path on

D:\). I’m wondering if Virtualization has some known problems if the User

Data folders have been relocated, and if there’s something I can do.

I wouldn't be one bit surprised if there is code that looks for a language

specific version of %homedrive%\users and that is what causes virtualization

to break.

I would be very disappointed if this was the case.

Are there any Path variables or registry objects File Virtualization uses

that I can check, such as the path of %LocalAppData%.

I have confirmed that secpol shows UAC File & registry Virtualization to be

enabled, it just doesn't appear to be doing it's job. There is no

VirtualStore folder and additionally no events in the UAC-FileVirtualization

event log.

Sorry to disappoint you, although I am conjecturing.

More than likely it uses the standard environment variables. There is

nothing specific to virtualization, but based on the symptoms, it is quite

certain that they are not using the LocalAppData variable. To start with, I

would fire up Process Monitor and see if I could tell what was failing.

How exactly did you move the folders? It could also be a permissions issue I

suppose.

NTFS symbolic link - Wikipedia, the free encyclopedia:

http://en.wikipedia.org/wiki/NTFS_symbolic_link

There's a KB I've seen (that I can't find right now) that talks about

this symbolic link issue.

Thanks for the help, I haven't quite fixed the issue but I have discovered a

little more about the problem. I opened Task Manager and selected the

Virtualization column in attempt to manually set the process to run as a

virtualized process however I found that all applications were listed as "Not

Allowed" and the Virtualization option was greyed out. This would definitely

cause the file virtualization to break.

This seems to indicate that something is disabling the virtualization

(policy perhaps), has anyone seen this before. I have checked secpol: Windows

Settings-Security Settings-Local Policies-Security Options -> all the

relevant UAC policies are enabled including "UAC: Virtualize file and

registry write failures...."

False alarm...I didn't realise I was logged in as the adminstrator, this is

why the Virtualization was set to "Not Allowed".
