I'm troubleshooting a windows 7 computer and notice that the System volume information is taking up 665.3 GB of a 900GB hard drive.

When scanning with TreeSize I see 71 files as per this screenshot. What can I do about this? Why do they take up so much space?

This folder is used for System Restore. In Control Panel\System and Security\System choose System Protection on the left. A window will pop up that will let you manage the used space. Typically 10% of the disk is sufficient.

Yes. I run at 5% and that helps too.

Run Disk Cleanup and when it is ready to start, click on the lower left button to Clean Up System Files. That will likely help as well.

One easy way to clear space is to disable System Restore and restart the computer.  Then, turn back on System Restore and manually create a restore point.

After that, I agree with Thinkpads_User and weifai, set the System Restore to a lower percentage.

Be aware in this situation, that reduction from 100 to 5 or 10% will clear out all the restore points and pretty much empty system volume information. There is no way to lower the consumed space without clearing restore points.

That is what I want. Why would I want to keep that many restore points that I will never use?

Or am I missing the point?

Just set to 10% and it will delete the older ones, i don't think you will ever use them.

Lowering the percentage will keep fewer in future as you are wanting.

But the initial reduction will remove them all, and then you build up again to your desired level.
