Will I need to re-install games after re-installing Windows 10

[chad thundercock]

So I might have to reinstall Windows 10 because of a few reasons. I just wanted to know if I will have to re-install all my games after the reinstall of my OS. Because 60gb games like GTA V will not be fun to re-download... If they wont, is there a way I can make it so I dont have to re-download them all?

Thanks :D

You could back up the SteamApps & userdata -folders on some external disk.

Do note that you will also want to back up your save files elsewhere, for which PCGamingWiki can be of use for, as well as GameSave Manager. (Typically under My Documents and AppData.)

You can check which games use Steam Cloud -saving by clicking [View > Games List].

You can save the data of the games at some BIG usb stick or some other extern save medium. Then just put it back in the PC after re-installing your OS.

Move your entire Steam folder (Or just move the Steam.exe + Steamapps folder) to another partition/drive.

If Windows is on C:\ , then move Steam to D:\ or any other partition you have. (External/USB drive perhaps?)

When you (re-) install windows to C:\ Partition, you still get to keep all the game content you downloaded from steam. Simply run the Steam.exe again in your Steam created folder, and you're able to re-discover existing content without the need to download everything all over again.
