Software Center Task Sequence Stuck Installing. Software center may show that updates are being installed and that some have a pending restart. Task sequence in software center is divided in 2 parts.
On most clients they run successfully. It was in stopped state. It can happen that we pull our hair out on this problem a user wants to install an application but the latter gets stuck in the Software Center on 0 download.
This may happen due to various reasons but to quickly fix the SCCM update download issues you can always make use of CMUpdateReset tool.
If you right click the Software Center icon in the notification area and click on Open Restart Window it doesnt give a timer of when it will restart just giving you the option to restart now or snooze. This happens because the machine rebooted before the SCCM agent can finish updating all the WMI classes or something has happened to WMI or the content but after. And you see the status of update is in downloading state and it is almost stuck. Scenarios the task sequence stops responding on the Install Software Updates step.
