Do you by chance have the PTR installed? With the way the update works, if you have the PTR installed, it’ll try copying those files in toe the live client rather than downloading them. We have seen cases where the process of copying the files can result in high CPU usage. If you’re looking to avoid this, then removing the PTR before updating or reinstalling the game completely should help.
I did not. Here’s what I did to remedy the matter though through elevated command prompt…
net stop winmgmt - stops the WMI Service
Respond in the affirmative to the warning message about stopping the Security Center and IP Helper (type Y and hit Enter)
winmgmt /resetrepository - this will report the WMI repository has been reset)
net start winmgmt - it may report the WMI Service is already started (that’s fine)
exit - closes the Command Prompt Window
Did that resolve the issue while the background download is occurring? The WMI service is used by the Blizzard app bug giving it a try on my own system resulted in the download restarting. As the download wasn’t running for a bit, CPU usage did drop which is expected.
I closed the bnet installer first, ran the commands and re-opened the installer. I did notice the system DID want to try to zip back up but was not capped out. Prior to closing out the installer populated 16.4GB data to download, after running the commands, installer populated just under 5GB data to download.
So it appears it has impacted the installer in a positive sense.
Awesome, thanks for the update!
