Ever wanted to create windows 8 tiles to shutdown/restart/logoff then the power shell script available here: http://gallery.technet.microsoft.com/scriptcenter/Create-a-ShutdownRestartLog-b4d75991 does the job for you.
1) Download the CreateWindowsTile (VBscript).zip from the above link
2) Unzip the contents and double click the ‘CreateWindowsTile.vbs’ file. This should create three tiles for you.
Hope this helps.
