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.

    Other users have reported a solution which resolves the issue, but it was for an older version so the folder version numbers will be slightly different:

    1. disable service click-to-run (in services - set disabled)
    2. restart computer (click-to-run will be not loaded)
    3. open C:\Users\Username\AppData\Local\Microsoft\Office\Spw and delete all files
    4. open C:\Users\Username\AppData\Local\Microsoft\Office\15.0\OfficeFileCache and delete all files
    5. enable service click-to-run (set automatic)
    6. restart computer

    Thanks for the help. I just ran the online repair via the Control Panel and it ran for nearly two hours with my slow Internet connection. It looks like the repair did a complete reinstall. The Office version remained the same. Unfortunately, the repair did not fix the problem. I enabled metered connection, rebooted, and the high CPU utilization returned.

    Yesterday I tried the offline repair also available through the Control Panel again without any change.

    Hi, I'm Elise, an independent advisor and I'd be happy to help with your issue.

    I would firstly try to run an online Office installation repair, and see if that resolves the issue.

    Please see this article for details on how to do this:
