Enable shell

Hi ,

I am using WinPe 3.1 and not able to enable shell support. 'EnableLabShell' value goed back to 'False'. I don;t get any error during saving it to 'TRUE' but still it shows be 'False' Once i'll close wbemtest and reopen the instance again. 

I am following http://technet.microsoft.com/en-US/library/dn387582.aspx 

1. You can enable a command shell in the boot image to debug and troubleshoot it in Windows PE. Use the following steps to enable the command shell.

   1. In the Configuration Manager console, click Software Library.

   2. In the Software Library workspace, expand Operating Systems, and then click Boot Images.

   3. Find the new boot image in the list and identify the package ID for the image. You can find the package ID in the Image ID column for the boot image.

   4. From a command prompt, type wbemtest to open the Windows Management Instrumentation Tester.

   5. Type \\<SMS Provider Computer>\root\sms\site_<sitecode> in Namespace, and then click Connect.

   6. Click Open Instance, type sms_bootimagepackage.packageID="<packageID>", and then click OK. For packageID, enter the value that you identified in step 3.

   7. Click Refresh Object, and then click EnableLabShell in the Properties pane.

   8. Click Edit Property, change the value to TRUE, click Save Property, and then exit the Windows Management Instrumentation Tester.
