If you use Storage Spaces, and this particular gremlin rears its head, you need to be very careful.
Windows 10 May 2020 Update is causing problems for some PCs which are using Storage Spaces, and in terms of being safer rather than sorry, you should avoid installing the latest update if you use this feature (although it may well be blocked from your device anyway).
As Microsoft explains in a support document, some configurations of Storage Spaces are proving problematic after upgrading to the May 2020 Update (also known as Windows 10 version 2004).
If you’re not aware of the feature, it allows you to pool multiple drives together, and the total capacity from that pool can be used to create virtual drives called Storage Spaces. These Storage Spaces can then be utilized to keep duplicate copies of your data, just in case of drive failure (so you can think of it as a kind of software-based alternative to RAID).
