When you are deploying a “big” software update like KB2919355, with System Center Configuration Manager, you can have the error code 0x800f0821 on some computers.
The computer receives the update, downloads it and starts to install it but the installation will fail.
Installation failed 0x800f0821
This error is raised because the execution time was reached. Depends on computers and servers, you may or not have this error on all SCCM clients.
Let’s see how to change the configuration in SCCM.
With Windows 10, Microsoft introduces a new method to get Windows Update. Before it, you can only download update from the Microsoft servers, but with Windows 10 you can also get update from computers already updated. It uses a technology like peer to peer (P2P).
By default, Windows tries to get update from Microsoft server, computer in your local network or from others computers on the internet. This new method speeds up the update download but it means that you can also send data to computers on internet. Depends on your upload rate, this can slow your internet navigation.
Let’s see how to disable this function:
System Center Configuration Manager 2012 brought the possibility for a collection to refresh its members using Incremental Update. It means that the collection will periodically evaluate new resources only, and does not execute a Full Update Membership.
SCCM Collection Incremental
By default, the interval is set to every 5 minutes. But if you want to increase or decrease it, you can do it easily with the SCCM Console.
When Microsoft release a new Cumulative Update for ConfigMgr 2012, the SCCM Agent is updated too with a new version. To fix some bugs and improvements, you need to deploy it on all your clients.
To do this, you can choose two solutions:
- Use the CAB file in the folder [SCCMInstall]\hotfix\KB\SCUP and deploy it with SCUP, that means you are using Software Updates.
- Deploy the new version with two packages, one for x86 and one for x64, included in the Cumulative Update. With this solution, you can easily update your client with no technical requisite.
We will see how to update clients with the second solution, using package.
