If the computer was recently upgraded from Windows 10 to Windows 11 the process creates a Windows.old.
This allows the end user to return to Windows 10.
After ten days the Windows.old is scheduled to be deleted.
The deletion can be performed manually as needed to create more drive free space.

There are multiple other files that can be deleted.

There are third party software that can be used to see the files and their sizes.

I am talking about the total space, not how many space left. It should be around 475GB. I have 512GB of SSD. The C drive total space is 475GB. I want to regain the lost space.

You should have been more specific in your original question.

Go to Disk Management. There are many ways to do that and many articles describing it and one of them is How to Open Disk Management in Windows 11 - All Things. What partitions are on the drive and how large is each of them?
