Still waiting for the vaccine? Trying to avoid going outside? Well, luckily for you, there are plenty of indoor tasks you can work on, like Netflix binge-watching, exercise, and installing software updates on your Windows computers.

For May 2021, Microsoft is handing us yet another pile of updates, addressing eighty-eight vulnerabilities (by my count) in .NET, Internet Explorer, Office, Edge, Exchange Server, SharePoint, Visual Studio, Skype, and Windows. My analysis is based on data exported from Microsoft’s Security Update Guide.

As usual, Windows 10 users can delay updates but not indefinitely. Windows 8.1 users who don’t have automatic updates enabled need to go to Windows Update to get the updates. Windows 7 users are mostly out of luck, but should check Windows Update anyway, because Microsoft sometimes makes critical update available for all users, not just business and educational users with deep pockets. If you’re still using Windows XP, there are no more updates, and I hope you know what you’re doing.
