Steps to remove the previous windows setup

From this blog, you will learn how to delete the previous installation setup without any software. Windows includes a Disk Cleanup tool, although it's a bit hidden. This tool frees up space on your hard drive by deleting useless files — old temporary files created by programs, temporary Internet files for Internet Explorer, Windows error report logs, and more. You can run this tool at any time to free up disk space.

So Let’s Start-

1:Click windows icon and search for Disk cleanup

                         

2:Now search for disk clean-up

3:Click the clean-up and select the drive where the OS is installed, usually OS is installed in C.

4:Now click clean-up and tick the previous windows installation/package. If it doesn’t appear again click disk clean-up. This time it will definitely appear.

5: Click clean-up, now your previous installation has been completely removed from your drive.
