How to Activate Windows 10 RTM (build 10240) without any software
After final release day version of Windows 10 on July 29, 2015 and it's activate is a simple way to procedure which I’ll describe below.
Once you have Windows 10 installed, you’ll eventually notice that even with the keys provided by Microsoft itself, the system deactivates itself after a day or so, and an intrusive, albeit transparent watermark appears in the bottom right-hand corner of your screen. But more importantly, your OS will be plagued with copious restrictions, particularly on the rationalization side. To avoid this, search Cortana for the Command Prompt and open it by right-clicking and selecting Run As Administrator. Note: don’t underestimate the importance of this step.
Now, copy and paste the phrase slmgr /ipk W269N-WFGWX-YVC9B-4J6C9-T83GX into the command line. Hit enter. After a few seconds, a new Window should appear, alerting you that the product key was installed successfully. Click OK. Then type (or copy/paste) the line slmgr /skms kms.xspace.in. Another window will pop up to which, again, you’ll respond by clicking OK. Lastly, compose the line slmgr /ato. This one might take a bit longer, but another window will pop up congratulating you on achieving your preeminent life goals or something.
If you have a volume license key, or VL version, of Windows installed, the process will look a little different. Instead of those other things I told you to type in the Command Prompt, type slmgr / skms kms.xspace.in, presumably followed by slmgr / ato.
When you’re done with that, the watermark should disappear and you’ll be greeted by a fully activated rendition of Windows 10 RTM, and you have CDM to thank. Thanks, me! If you have any questions, feel free to leave ’em in the comments below and I’ll try to respond to them with utmost professionalism or, alternatively, an ostensibly distressing joke about suffocating in my own self-deprecation.
