What operating system/systems do you have installed on your computer/computers? I have eight computers although one is not usable in its current state. Here's what is included on each of them:
Acer Aspire A315-21: A multi-boot of Windows 7, 8.1, and 10. Will be expanded to include the potential Windows 11 when that drops as well as Vista once the Extended Kernel works with Windows 7 drivers.
Acer Aspire R3-131t: Windows 8.1
Acer Aspire E1-531 (broken): Windows Vista
Acer TravelMate 2480: Windows 2000
Dell Latitude E6400: Dual-boot of Windows XP and Vista
Dell Inspiron 3847: Windows 8.1
Dell Inspiron 15 3565: Windows 7
HP 15-f233wm: Windows Vista
And this is what I have and what is installed to each of them. Also included is a picture of This PC from the laptop I am currently using.
