Monitoring with PowerShell: Monitoring Storage Sense settings

So let’s talk about Storage Sense. Storage Sense is a new-ish feature in Windows 10 which should replace the standard disk cleanup utilities. It has a lot more power than just disk cleanup as it can detect how long files have been in use and react based on age.

Storage Sense is pretty easy to use and can save a lot of disk space for modern clients, especially when they use OneDrive too. Storage Sense has support for OneDrive files on demand. By default it does not clear anything, but it could be setup to clear the local cache if files have not been in use for days, weeks, or even months. This helps with those pesky OneDrive database size limits.

So the first blog about Storage Senses will be monitoring its optimal settings. We’re using the RunAsUser Module for this, because the registry keys will be located in the HKEY_Current_User hive.

And that’s it. Next week I’ll be demonstrating how to setup Storage Sense automatically, including adding OneDrive sites. As always, Happy PowerShelling!
