Here’s all the security and general bug fixes for April, aimed at Office 2016, Office 2013 and Office 2010 for Windows.
Most customers will have their Office updated automatically unless you’re one of the cautious who wait a little while to see if there’s any bugs in the bug fixes. See Why updating Office is like the Kobayashi Maru a ‘no win scenario’
Update side-effects
This month’s updates come with warnings about possible side-effects, just like a vaccination!
“ Some Office files, templates, and add-ins can be manipulated to harm your computer. After you install the April 2021 security updates for Office, your computer might display a notification and disable some of these files, even if the files were originally obtained from Microsoft. For more information about this issue and how to re-enable the disabled content, see KB5001196. “
Office 2013 and Office 2010 have other post-update troubles related to additional language packs. See the Microsoft page for details.
Office 2016
The important fix is for a bug which makes an Office app stop responding. In this case because of a registry setting. The fix is to install this KB4486672 update AND add a new registry key.
Key: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\General
Type: DWORD
Name: EnableAdvancedRegistryHangDetection
Data: 1
It’s not explained why the registry change is needed in addition to the patch. Surely the patch could update the registry?
