Hi Windowuser5953 -
I'm Jerico T., I understand that you're having some issues right now and I'd be more than happy to help you today.
C:\swsetup is where I believe the installation files for most of the drivers is located. Deleting it will not cause you any harm on your computer, but to make sure, I suggest that you create a Restore Point so that in case you encounter any complications during or after the deletion, you can reverse the changes on your computer. Click the link below for the steps.

Hope this help. Have a good day.
Thank you,
Jerico T.
