Re-tested with Development Snapshot 169670 (15 July 2025). Guest Additions installation still fails. Seems to be caused by Certificate error(s). Latest Installation log attached.

On a positive note Windows ARM VM startup time seems to have improved a little, but all 'network activity' still seems to be indicated by a pulsing red blob on the USB taskbar icon Little/No USB connection activity is expected, as no USB devices are attached to the VM(s).

Heavy Disk and Network activity also seems to be very lengthy and excessive, i.e. heavy 'traffic' is indicated on the taskbar for more than 5 minutes after initial startup without any user interaction.

This problem continues on 7.2.0_RC1, with certificate errors.

Thanks for your test results - Saves me one task for this weekend

This problem is fixed with Guest Additions development revision 170202

Yes, happy day! Guest Additions now installing correctly on Windows 11 VM (VirtualBox Dev Build 170131 with Guest Additions Build 170202)

Features Tested (so far):

- Shared Folders working with no apparent problems - A clear advantage over using current VMware Fusion or UTM installations.
- Screen 'resizing' options - All appear to be available and working after changing the Display Controller to VBoxSVGA - Previously could only use the QemuRamFB setting, which now shows as an 'Invalid' choice.

Yes, apologies, wanted to mention it yesterday already but the day was too short. Turned out to be purely a code signing issue of the graphics driver which sabotaged the installer.
