To clear the Configuration Manager client cache with PowerShell, use the client’s cache-management interface rather than deleting files from ccmcache directly. The example below removes every cache element returned by the client; it is an all-cache cleanup, not a selective cleanup.
PowerShell script to clear the client cache
Run this in Windows PowerShell on a computer with the Configuration Manager client installed:
[__comobject]$CCMComObject = New-Object -ComObject 'UIResource.UIResourceMgr'
$CacheInfo = $CCMComObject.GetCacheInfo().GetCacheElements()
foreach ($CacheItem in $CacheInfo) {
$null = $CCMComObject.GetCacheInfo().DeleteCacheElement(
[string]$CacheItem.CacheElementID
)
}The script retrieves the cache elements reported by the client and calls DeleteCacheElement for each one. Microsoft’s archived PowerShell example uses this COM-based pattern. The source does not establish that clearing every element preserves content needed by active deployments or content marked to persist, or that this COM interface is supported across every Configuration Manager release. Use it with that scope in mind; the example is not a guarantee of compatibility for all environments.
Use Microsoft’s documented interactive method instead
If you want to clear the cache through the documented client interface, open the Configuration Manager control panel applet, select the Cache tab, then choose Delete Files. Microsoft advises against removing cache files manually because the client tracks cache content separately from the files on disk. See Microsoft’s cache guidance.

Why you should not delete files from ccmcache
The client cache holds temporary content used to install applications and programs; software updates also use it. Microsoft documents the default location as %windir%ccmcache and the default cache size as 5120 MB. Those are documented defaults, not requirements for every organization or device. Microsoft’s cache configuration page
Do not use File Explorer or a command such as Remove-Item to erase files directly from that folder. Microsoft warns that manual deletion can cause Configuration Manager client issues. Use the client’s cache controls so its records and the content on disk remain coordinated.

What happens to cached content over time?
Configuration Manager generally removes cached content when new content needs space, subject to the configured minimum retention period and whether content is configured to persist. The minimum-retention setting defaults to 1,440 minutes (24 hours) and can be set as high as 10,080 minutes (one week), according to Microsoft’s client settings documentation.

Rather than repeatedly clearing everything, review the cache size and retention settings applied to the affected device. Client cache size can be changed through client settings without reinstalling the client. Custom client settings deployed to collections override default settings, so check which settings apply to the device before changing them. See Microsoft’s instructions for configuring client settings.
