This update finally fixes *some* of the Windows guest display issues. Start Menu Shortcuts, app icons in the Store Library, the Get Updates button in the Store Library, text in Notepad when using dark mode, & the flyout menus when you right click the Start Button all display properly now. [There may have been more issues I'm not aware of.] Very occasionally Windows will show a sign-in pop-up for OneDrive, or show a screen just after login to finish setting up Windows, e.g., linking your phone etc., and those windows continue to flash Very rapidly.
I had problems installing the new version Guest Additions however, similar to the 1st v. 7 releases. In my hardware qualified Win11 VM, setup caused Windows to hang during the graphics driver update. Trying again in Safe Mode it crashed Windows with a BSOD. Still in Safe Mode I uninstalled the Guest Additions, then ran setup for the new version Guest Additions successfully. In the interest of time I used the same procedure with the rest of my VMs, so I don't know if uninstalling the Guest Additions 1st while running a Windows VM normally would allow the new version Guest Additions to install.
