on
The challenge with sensitive data and access to Copilot Microsoft 365 Copilot empowers users with AI-driven assistance across Microsoft 365 apps, but it also raises concerns about accidental oversharing of sensitive information. In response, Microsoft has extended its Purview Data Loss Prevention (DLP) capabilities to Microsoft 365 Copilot, allowing organizations to enforce information protection policies within AI workflows. The DLP for Microsoft 365 Copilot has been in preview for some time, but Microsoft has now announced it is released for GA (General Availability). Among some of the interesting features are new features like alerting and policy simulation. Key details:  Rollout Timeline: As of June 2025, the rollout has begun. It should be completed worldwide by late July 2025. Scope: Initially, DLP for Copilot was available for Copilot Chat scenarios.

Saving space with differencing disks?

on
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)
