Bug report: WDS Server, Browse button do not work in WDS installed in stand Alone mode!

Browse button do not work in "Windows Deployment Services" console.

This BUG exist also in  Windows Server 2012 R2.
The BUG exist in English-US, French, and probably other languages (not related to a language)

To produce the bug do the following:

On www.msdn.com download Windows Server Technical Preview 

At command prompt install WDS Server role in StandAlone mode with the folowing command:
PowerShell  Add-WindowsFeature  WDS   -IncludeManagementTools   -IncludeAllSubfeature

Initialize the WDS role "IN STAND ALONE MODE" with the folowing command:
wdsutil /verbose  /progress  /initialize-server  /server:localhost /REMINST:C:\RemoteInstall   /StandAlone

The bug exist only if WDS is installed in standalone mode !

To create a "prestaged device" and associate to this device an answer file we need an "answer file".
To reproduce the BUG  a simple text file can be created with notepad in C:\RemoteInstall\WDSClientUnattend folder with the name PC1.xml. The content of this file is not important to reproduce the BUG.

Now we will create a local "Prestaged Device" and will try to associate with the already existent answer file that we have created C:\RemoteInstall\WDSClientUnattend\PC1.xml:

ServerManager, Clic "Tools", select "Windows Deployment Services"

Click "Servers", Click on the name of your server, Right Click "Prestaged Devices", Select "Add Device",

( Do not confuse "Prestages Devices" with "Active Directory Prestaged Devices" because "Active Directory Prestages devices is not available in Stand Alone mode),

Name: PC1
DeviceID: 123456123456, Clic "Next"

On the page "Boot", Clic "Next"

On the page "Client Unattend", to see the bug click "Browse", Clic "C:", Clic "RemoteInstall", Click "WDSClientUnattend", Clic "PC1.xml"

You can see that the PC1.xml are NOT added as "Unattend File".

BROWSE BUTTON FAIL TO ADD THE SELECTED ANSWER FILE ! You can clic Next buton but your selected file ARE NOT ASSOCIATED WITH THE PRESTAGED DEVICE.

My opinion is: The path to Unattend file must be relative to C:\RemoteInstall and must NOT contain C:\Remoteinstall.

If you clic on Browse button you will indicate a FULL PATH and this is not accepted because the BUG. Also if you fill manually a FULL PATH next to Unattend File this is not accepted. Only file path relative to C:\Remoteinstall are accepted. This can be very confusing for somebody who do not know this.

WorkAround:
Insted of clic on Browse button, you can write the relative path:  "WDSClientUnattend\PC1.xml",
Clic Next, Click Back, You can see that Unattend File is WDSClientUnattend\PC1.xml and this is right.

Conclusion: relative path are OK, Full path including C:\RemoteInstall are not accepted. Browse button do not work !
