Microsoft has released at least two zero-day patches, and you will want both on your system as soon as possible.

Windows Update: Most of you have automatic updates in Windows, but you’ll want to manually install them today – and as soon as you read this. Click Start > Settings > Windows Update. If there is a link for “optional” updates, click the link and select every update – the only exception is the upgrade to Windows 11 for you Windows 10 users. While you may want to upgrade, it is not necessary at this point.

Office Update: To install updates and patches for Microsoft Office, open any Office App (Word, Excel, Outlook, etc.), click File > Office Account, then click the button for Update Options and click Update Now.
