Hello Mike,

 

I hope will get some answers to my questions. I have tested Express Update and my opinion is better to leverage Full Update or LCU update types to patch our End User Devices until really MS bring improvements.

 

Reasons:

 

1.  We deploy Monthly patches to End User Devices through Microsoft SCCM CB integrated with WSUS. We have quite number of Distribution Points connected at slow network sites especially PULL DP concept. During our testing scenario; we realized the Express Update occupies the Disk Space on DPs more than LCU update types. We are worried about the replicating 7GB to 8GB package to the Distribution Points hosted at low network bandwidth locations. I am quite disappointed; When MS releases so many feature across different product groups and at the same time its impacting the other products. We deployed PULL DP with the concept of Branch Office sites and now we will not be able to utilize Express Updates because of content size limitations.

  

Questions: Lets take a scenario; Now we are in the month of July 2018. For now my Express update package has cumulative updates from January to June 2018 and size of approx. 7GB to 8GB. Lets assume we will move to December 2018 and we will have Express Update for the last one year including LCU and the content size approx.. ??.. Can I cleanup the content library or content directory of Express Update (n-2) months which means till October 2018 to get back some disk space free. If I do so; how does it impact the Client Devices to scan and installs the Windows Updates particularly in the space of Express Update.

 

2. Bad End User Experience : Express Updates takes quite a lot to download and installs the Updates. One more Bad User Experience; SCCM Client Agent downloads and keep the binaries @ C:\windows\ccm\temp and estimated disk space of 100 - 300 MB.  After completion of deployment; these files are not cleaned up and cause the Disk space utilization on End User Devices. I am not sure; does it by design with Intention? Could you please advise me do you have any information and When MS expected to announce the improvements any ETA?
