Problems with Windows 7 shares

Do you still run a Windows 7 computer that has shared folders? If you do, and those shares are set up so that they require user authentication, and the user involved is a member of the Administrators group on the Windows 7 computer, then you may find that those shares stopped working recently.

This problem was triggered by one of the Windows 7 updates from January 2019. Uninstalling that update fixes the problem, but doing that also rolls back some important security updates. So that’s not really a viable option.

Thankfully, Microsoft issued a fix for the problem. I’ve tested this fix and confirmed that it does work. To install it on your affected Windows 7 computer, locate the appropriate update (KB4487345 for 32-bit computers; KB4487345 for 64-bit computers) on this Windows Update Catalog page, click to download it, run the download and respond to the prompts. You’ll probably need to restart the computer.
