VBScript

I designed a vbscript that deletes folders from a root folder older than 180 days without any user intervention.The script deletes all the folders except the built-in folders Desktop and Documents.I get the error access denied whenever the script attempts to delete those folders.The sub-folders within the Documents and Desktop folders are deleted though.If i manually create the root folder and copy the built-in Documents and Desktop folders and manually delete the built-in folders, the task is performed successfully without any errors.
