Αν εγκαταστήσατε τα Windows 10 σε PC με Windows 7 και 8, θα παρατηρήσατε ότι το εργαλείο λήψης και installationMicrosoft first downloads the new operating system, stores it locally, and then starts the installation.
This of course happens if you choose to install immediately and not "Upgrade this PC now" and not download the ISO.
If you choose to download Windows 10 to an ISO file, it will save the file where you choose.
But what if you select "Upgrade this PC now"?
Who stores the installation files the Microsoft tool?
Before we give you the save path, you should allow Windows to display hidden folders.
Follow the steps as described from below picture (1, 2, 3). For those who can't read the image: Control Panel/ Folders and Options/ and on the View tab select show hidden folders. Then Apply and OK.
After allowing Windows to display hidden folders, let's look at the path from where you can find the installation files.
Open any folder and copy and paste the following on the line that shows the path:
C: \ $ Windows. ~ WS \ Sources \ Windows \ sources
If your operating system is not installed in C: \ change the first letter of the path.
With the files you find in the path, you can make an ISO or copy it to a USB flash drive.
You should know that after installing Windows 10 the files remain where you found them. If you want you can delete as they use some gigabytes on your disk.
