Hi guys, a few days ago i was upgrading windows 7 to 10 and when it was installing or configuring the new OS i accidentaly unpluged the PC, and as it has no battery, it turned off. When i restarted it came back to Windows 7, so i tried to reinstall but Windows Update whant to download it again. As my Internet conection is really slow, is it possible that windows has saved the installation files to avoid downloading it again ?
