updated windows 8.1 and lost 50gb on my ssd!

So i just go a new laptop with a 128 ssd, the laptop has a 128gb ssd and had windows 8.1 pre installed. at first I had about 100gb free. I wanted to upgrade to windows 10 but I could not find the "get windows 10" app. A troubleshooting scan from Microsoft's website suggested me to download an update and install it. so I did it and it worked, windows 10 app appeared. Anyways, after I updated I noticed my ssd went form 100gb to 50gb of free space and I have no idea why! could anyone tell me why and maybe get this space back?

There maybe a windows.old folder on the hdd. If you dont want it use disk cleanup to remove it

Or do a clean install wipe it. If you dont want Win8
