How to Remove Linux Downloaded and Extracted files in C: drive?

I was trying to dual boot Linux Mint Cinnamon with my Windows 10 PC. I used Unetbootin to install linux mint cinnamon iso file. I used the hard drive type installation in which the only hard drive in the option was C: drive. The Unetbootin installer completed successfully. Now I want to remove every of those linux mint files from C: drive. I have tried System Restore twice. I also get a message saying system restore was successful but still my Linux files are not removed at all. I have tried manually deleting using Date modified and Date created but wasn't very successful using that. PS: Would reset my PC work? would it remove Linux files from my C: ? Please Help. Thank you. **Update:** While trying to install Linux through USB, somehow my windows file got effected. My PC was not booting to the desktop screen. It always came to a blue screen that said > Your device ran into a problem and needs to restart. We're just collecting some error info, and then we'll restart for you.The image is included along with an error image that I also saw in my PC. This happened **every single time** I restarted it. I know that only my C drive was effected because I booted using a Linux OS from a USB and my rest of the files were fine. After 3 hours of panicking and trying out reset my pc (which failed), system restore (which was successful but still couldn't boot my pc), some scans from cmd terminal (which gave msg - Windows Resource Protection could not perform the requested operation.), I resigned myself that I would have to take it up to a technician. As a last ditch effort, I tried System Restore at a later date than my previous restore points. It WORKED!! I don't know why that did and the other didn't (even though I had NOT installed linux in any of the restore points) but I was crazy in relief! My windows is back to normal. I am very grateful for it. Thank you everyone for your help.
