Microsoft is unlocking the "Full Potential" of Private Channels in Microsoft Teams: What You Need to Know

It has been a while since I posted something just about a Microsoft Teams update, as a lot have been Copilot in Teams to be honest. But here is a real Microsoft Teams update I think is worth knowing about, and it involves Security and Compliance as well. Microsoft is rolling out a "major" update to private channels in Teams, starting in late September 2025 and continuing through mid-December. This biggest change in this update is a shift in how private channel data is stored from individual user mailboxes to a dedicated channel mailbox. Not only will this simplifie compliance management, it will also and align private channels with shared channels, making governance and experience more consistent across Teams. This update promises to increase the support up to 1000 channels per team and 5000 members per channel, removing previous limitations. Teams will also allow meetings to be scheduled directly within private channels, enhancing collaboration.  For organizations using Micr...

Saving space with differencing disks?

I just read, and followed this article on differencing disks: http://www.andrewconnell.com/blog/articles/UseVirtualPCsDifferencingDisksToYourAdvantage.aspx

It was really helpful for a first timer like me. In my daily work I have to access different customers’ remotely, and they all have different ways of logging on and different security requirements. To help me with this, I have set up a couple of virtual pc's. The only problem so far, has been the lack of space on my hard drive. But thanks to this article, I have saved a lot of space. I now only have 1 core disk with the operating system and basic functions. Then I have one VM, and diff-vhd for each customer.

In addition to the tips this guy have, there are a few things I want add to "what to do to the base".
If you're really keen on saving space, I would run cleanmgr on the disk first of all. Then I would look for hidden files and folder containing uninstall information on service packs and patches (Let's face it, if you're creating a static core, you're probably not going to uninstall these patches). After cleaning up, go through basic settings you like to set to your image. From the top of my head:
Remove all visual effects you don't need
Stop services you probably don't need (don't worry, you can enable them later, if needed)
Start a few programs, and set your "standard settings"*
Then continue with the final preparations described in the article (and don't forget to sysprep if you want different SIDs in your environment.

(* One good example is Internet explorer. I always set my preferred homepage, usually blank, adjust some settings in advanced settings, set a preferred search engine and so forth. Since I "always" do it, it only makes sense to set it once, in the core)
