Activate Windows 10 without product key
STEP 1 [DOWNLOAD WINDOWS 10]
You can download the 32-bit (x86) or 64-bit (x64) according to your choice, but I will recommend you download the Windows 10 32-bit if you have 4GB of less amount of RAM and 64-bit if you have RAM higher than 4GB
links are for Windows 10 64 Bit / 32 Bit
Create a bootable USB drive Or Create a bootable CD drive and Install it
STEP 3 Download [KMS TOOL]
Before you install disable the Windows Defender real-time protection as it thinks that the program may hurt your system. This is because, some system parameters are modified in order to activate Windows 10 without product key and hence the Windows Defender alarms you. After you have downloaded run the installer. Just click next, agree to terms and conditions and install it. After you have installed KMPSPico, run the program as administrator and click on the activator button as you can see in the screenshot.
