I wanted to reinstall Windows via a stick, but I read that you need a Windows productkey for that. Problem is that Windows 10 was preinstalled on my laptop and I therefore have no key. Can I still reinstall it without Key? Because I have the problem that my laptop can't reset and therefore I wanted to install a stick.
On the laptop itself (on the bottom or back side) you will find a Windows 10 license sticker, this licensing can be used for reinstallation.
There's a program that is keyviewer or There's software on chip with which you can read the key. Then you would have to write it out to you, only then I would boot from the stick and install.
You do not need a new product key.
Once Win10 has been installed and unlocked on your laptop, it can be installed any number of times without entering a product key.
The activation then takes place automatically, at the latest at the first Win-Update.
You can get the Win10-Download via this page: https://www.microsoft.com/.../windows10, where you can download the "Tool" (= Media Creation Tool).
Double-click on the downloaded Media Creation Tool to get ready for the download preparations.
In a selection menu, see:, you select the empty USB stick.
After that, the Win10 ISO file will be loaded bootable directly on the USB stick.
This can be booted for the installation of the USB stick,
a) When you start the PC by simultaneously pressing a certain F-key *, you will open the boot menu and select the USB drive.
b) or you go to the UEFI * and put the USB drive in front of the HDD at the boot order of the drives.
The path via the boot menu (if available) is easier.
*) Which F-key or How to get into the UEFI, is in the user manual of the laptop.
