Microsoft Office Click-to-Run (SxS) High CPU

Anonymous

I am using Office Home & Student 2019 with Windows 10 Home. The June update was recently completed to Version 2005 Build 12827.20268.

After installing this update I noticed that Microsoft Office Click-to-Run (SxS) showed continuous 24% CPU utilization in the Task Manager. Power usage was shown as very high. This did not occur prior to the update. I have metered connection set in the network settings and discovered that the problem goes away if I turn off metered connection and restart the computer.

Does this sound like a bug in the latest update? I have Office 2013 on another computer and there is no problem on that system with metered connection set. I'd be interested if others have seen this problem or have any suggestions.

Hi KenBell6 & Everybody else,

Just got latest update for my version of Office (Office 2016 ProPlus Retail - 32bit).  Found it on Current Preview Channel.  Downloaded it and rebooted my PC and CPU Usage is back to what it used to be.

Don't know if it's a permanent fix, hope it is, but it seems to be working fine so far, after 3 reboots (just to play it safe).  I have several Office apps open, and as you can see above it looks pretty good.  Good luck everyone, let me know if it worked for you.

    Hi everyone,

    Version 12827.20336 has been released according to https://docs.microsoft.com/en-us/officeupdates/update-history-microsoft365-apps-by-date. Could someone please confirm that it solves the issue?

    I am on a metered LTE connection until Friday evening, updating the office and then re-installing it would take too much time. :(

    I just updated to Version 12827.20336 and unfortunately it did not fix the problem.

    It appears to only address a list of security updates.

    Not working. Don't waste bandwidth. Never update any Microsoft product unless there is an issue. My CPU reached 100+ and shutdown automatically. Reinstalling made way worse.
