I only use Windows 7 on my Mac Parallels Desktop 10 virtual machine only every now and then. There are still some CAD & industrial automation tools, which do not ship on OSX. So, as the Download-Windows-10 app showed up at the Windows 7 taskbar these days, I directly registered for a Windows 10 update.

Parallels today announced version 14 of its desktop virtualization software for Mac, offering macOS Mojave support out of the box and significantly improved application launch speeds over the previous version.
This update puts a heavy focus on enhanced storage optimization, with Parallels Desktop being around 20-30 percent smaller than earlier releases. The company says virtual machines can also save as much as 20GB of additional disk space depending on how they're configured.
Elsewhere, the developers have optimized the compression of memory states saved with the Snapshots tool, which takes on average 15 percent less storage space, while a new disk space wizard provides users with suggestions on how to economize storage, with advice on managing multiple virtual machines and VM snapshots.
In addition, Parallels 14 introduces several Windows features for use in macOS. For example, Microsoft Ink is now available for editing Office documents, and stylus support has been added to CorelDRAW, Fresh Paint, PowerPoint, Adobe Illustrator and Photoshop.
Parallels Desktop also now includes Touch Bar features on compatible MacBook Pros for OneNote, AutoCAD, SketchUp, Microsoft Visio, and other apps, while a Touch Bar wizard offers users the ability to customize Windows app shortcuts from Apple's OLED function strip.

Lastly, Parallels Toolbox has received some additional Mac features including new options to screenshot entire web pages, resize images and perform memory consolidation functions.
