OPERATING SYSTEMS
Microsoft Windows
You can download a Windows 10 Disc Image (ISO File) to install or reinstall Windows 10. Note that the instructions include creating bootable installation media on a USB flash drive, so it could be a tad technical.
Once you have installed Windows, delete the temporary files. While these instructions cover doing that in all the versions of Windows, it is not safe to dabble in any Windows operating system that predates Windows 10.
