Latest Office Insider Beta build for Windows fixes high CPU usage bug in Excel, and more

Office Insider program

Microsoft has released a new Office Insider Build version 14530.20000 for the Beta channel. The new build brings, as usual, several changes including features and bug fixes. Perhaps the most significant bug addressed with this release is a high CPU usage issue for Excel using a cell reference in a formula. This fix should be immensely helpful to users out there who don't have powerful systems with many-core processors. A high CPU usage bug in such systems can lead to a very unresponsive system overall, hindering work.

A new photo-adding feature for your Outlook profiles has also been added with this build. You can read all the changes below:


  • Update your photo using link in contact card

    • We’ve added a new way for you to update your photo in Outlook. Now when you open your own contact card, a new link appears under your name and title. Click on Update your photo to go to the web page where you can change the photo associated with your Outlook profile.


  • We fixed an issue where using a cell reference in a formula caused users to experience high CPU usage.


  • We fixed an issue where the application would stop responding when the user selected File > Save As.

  • We fixed an issue where the app would close unexpectedly when the user clicked on comment text while dictating a reply to that comment.

  • We fixed an issue where the Read Aloud playback sometimes jumps to a random location in the document.


  • We fixed an issue related to reordering bulleted list items using drag and drop.

Office Suite

  • We fixed an issue where an update would stop responding. The update would open Software Center as expected; it would start the “download and apply” phase, but then would stop responding and an error would appear: 0x87d00668 (“Software update still detected as actionable after apply”).
