Here is an example PowerShell script to demonstrate how to properly remove items (Packages, Software Updates, etc) from  the ConfigMgr Client Cache that have not been referenced in the past 60 days:

   1: #Connect to Resource Manager COM Object

   2: $resman = new-object -com "UIResource.UIResourceMgr"

   3: $cacheInfo = $resman.GetCacheInfo()

   4: #Enum Cache elements, compare date, and delete older than 60 days

   5: $cacheinfo.GetCacheElements()  | 

   6:     where-object {$_.LastReferenceTime -lt (get-date).AddDays(-60)} | 

   7:     foreach {$cacheInfo.DeleteCacheElement($_.CacheElementID)}

   8:     

 

The following is an example VBScript to delete all items in the local cache:

   1: on error resume next

   2: dim oUIResManager

   3: dim oCache

   4: dim oCacheElement

   5: dim oCacheElements

   6: set oUIResManager = createobject("UIResource.UIResourceMgr")

   7:   if oUIResManager is nothing then      

   8:     wscript.echo "Couldn't create Resource Manager - quitting"

   9:     wscript.quit

  10:   end if

  11: set oCache=oUIResManager.GetCacheInfo()

  12:   if oCache is nothing then

  13:     set oUIResManager=nothing

  14:         wscript.echo "Couldn't get cache info - quitting"

  15:         wscript.quit

  16:   end if

  17: set oCacheElements=oCache.GetCacheElements

  18:     for each oCacheElement in oCacheElements

  19:         oCache.DeleteCacheElement(oCacheElement.CacheElementID)

  20:     next

  21: set oCacheElements=nothing

  22: set oUIResManager=nothing

  23: set oCache=nothing

Either of these scripts can be distributed using normal ConfigMgr software distribution – You must have PowerShell installed on the client to successfully execute the PowerShell script.
