Clean ConfigMgr Client Cache

Method 1 - Create and Deploy Package to collection

Create a Package with the following powershell command to clean client cache

  PowerShell.exe -ExecutionPolicy Bypass -File <Script UNC location>\Clean-CMClientCache.ps1

  Set package running as normal and run whether the user log in or not

Method 2 - Run Script against collection(s)

Use Script feature in ConfigMgr to clean client cache

  Create script in ConfigMgr console and import Clean-CMClientCacheForce.ps1 from UNC

  Ensure only the Force script is used for Script deployment as regular version's parameters are not compatible with run script feature

  Approve the script

  Deploy the script against a collection

Method 3 - Create CI/CB and deploy against collection(s)

ConfigMgr CI/CB can be used to clean up client cache

Approach

Discovery script:

Find out the maximum cache size for Config Manager Client cache by using

  $maxCacheSize = (Get-WmiObject -Namespace ROOT\CCM\SoftMgmtAgent -Class CacheConfig).Size

Find out the current C:\Windows\ccmcache folder by using

  $currentCacheSize = ((Get-ChildItem C:\Windows\ccmcache -Recurse | Measure-Object -Property Length -Sum -ErrorAction Stop).Sum)/1M

Divide the $currentCacheSize by $maxCacheSize, if the result is more than 0.75 (75%) return $true

  Create Configuration Item with above discovery content in discovery script

  use Clean-CMClientCache.ps1 as a remediation script

  Omit 'Host' in -LoggingOption parameter to suppress any console output

  Create Configuration Baseline with above Configuration item 

  Deploy the Configuration baseline to the collections - make sure to mark Remediate noncompliance rule when supported and set schedule for every month

Creating ConfigMgr client cache report

Add CacheConfig hardware inventory class by adding it in client setting --> Hardware Inventory --> Add --> root\ccm\softmgmtagent and add CacheConfig class

use the following SQL query to construct a report

  SELECT       
  v_GS_LOGICAL_DISK.SystemName0 AS Name,
  v_GS_LOGICAL_DISK.Name0 as Drive,
  v_GS_LOGICAL_DISK.Size0 AS DiskSizeMB,
  v_GS_LOGICAL_DISK.FreeSpace0 AS DiskFreeSpaceMB,
  v_GS_CACHECONFIG.Size0 AS SCCMCacheSizeMB,
  ROUND(1.0 * v_GS_CACHECONFIG.Size0 / v_GS_LOGICAL_DISK.Size0 * 100, 0) AS PercentOfDisk, v_GS_CACHECONFIG.Location0 
  AS SCCMCacheLocation,
  v_GS_OPERATING_SYSTEM.Caption0

  FROM            v_GS_LOGICAL_DISK
  INNER JOIN
  v_GS_OPERATING_SYSTEM ON v_GS_LOGICAL_DISK.ResourceID = v_GS_OPERATING_SYSTEM.ResourceID RIGHT OUTER JOIN
  v_GS_CACHECONFIG ON v_GS_LOGICAL_DISK.ResourceID = v_GS_CACHECONFIG.ResourceID
  WHERE       
  (v_GS_LOGICAL_DISK.DriveType0 = 3) AND (LEFT(v_GS_CACHECONFIG.Location0, 2) = v_GS_LOGICAL_DISK.DeviceID0)
