Hi
Welcome to the Microsoft community.
What is the C disk space of your three windows 11 computers? Is it possible that the system cannot allocate extra space due to insufficient space.
By the way, you can delete the anti-virus software in your computer. The anti-virus software may also cause many redundant spaces to be deleted in time.
Looking forward to your good news.
You are welcome to reply to this topic, and I sincerely thank you for your support of Microsoft products and services.
Best regards
