If you need to clean install Windows on your PC it can be a chore to download Windows Updates afterwards, and make sure the PC is up to date with the latest security and stability patches. Fortunately Microsoft provide downloadable copies of Windows that are always kept up to date. Downloading one of these versions will ensure that you will only need to later install updates from the last month or so. There are three links, for Windows 10, Windows 8.1, and Windows 7, and you can click the icons below to take you to the downloads.
CAUTION: Only ever download Windows images from these official Microsoft links. Do not ever download a Windows image from a third-party source.
