How to get free Windows and Microsoft Office product keys

Recently, I have heard many stories round to software licenses. Many of you guys mail me and complained that their Windows suddenly became unlicensed after getting the latest updates. Others have troubles reactivating their Office license after replacing their old HDD with a new SSD. I know exactly how you feel and the reason why you angry but I think you should get in touch with the Microsoft support team instead of emailing me because I just have expirences in supporting issues related to KMS licenses. However, if you want to get a free license key in order to continue to work immediately, I think the following guidelines can help.

Types of free Windows and Office license keys

Before we start, let me clarify a little. Currently there are two types of free license: educator/student license pack and trial license. Education license pack is exactly the same as commercial and retail one. However, it is for teachers and students so of course you can not take it if you do not belong to this group. And what about trial one? As you know, the trial license is totally free and a program activated by using trial key still has all features so it is the perfect choice for others, anyone else not in the group above.

Free 180-day trial license

Microsoft lets you try out most versions of Windows for 30 days only. After that, some important features will be limited. For example, in Windows 10, you will not be able to personalize your PC after the free trial ends. The trial license is completely legal, but its period can not be extended. This means we can do nothing about it. However, there is an alternative to 30-day trial license, it is to use KMS license.

At its most simplistic, KMS license is almost similar to trial one and it is valid for 180 days only. Importantly, it can be renewed without limit on the numbers of activation. This makes a difference. You can extend the trial period and unlimitedness is equivalent to “forever”. It must be so. The following is the latest list of product keys I get from the official page of Microsoft.

You can use them to activate your current product for free. The specific instructions for each product was posted before. You can find them in this page.

Weakness of using KMS license

Because it is the same kind of trial license so you can not compare it to retail one. The 180-day trial license will expire unless you renew it, whereas for the other, you do not need to concern yourself with the matter because your product has been activated permanently.

Additional information: By default, your KMS license will be renewed automatically every 7 days. So you do not have to worry about doing it manually.

If you would have any questions or concerns, please leave your comments. I would be glad to explain in more details. Thank you so much for all your feedback and support!

    Error: 0xC004F074 The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information.

    1. run the Windows 10 Activation Troubleshooter as well. Go to Settings > Update & Security > Activation > Troubleshooter. Wait until the tool completes the troubleshooting process, restart your computer and check if the error code 0xc004f074 persists.

  11. Hello there!
    So for some reason my windows won’t activate, it says “Error code: 0x8007007B”
    Can you please help me? 🙂
    Thanks in advance!

    1. If the 0x8007007B error is caused by corrupt system files that are preventing the activation of your Windows license key, running the System File Checker (SFC) will automatically resolve the issue.

  12. Saved all original files as cd.
    Disc image file.
    Just had to reinstall for an unrelated error to this program.
    New since last install = KMS – you must manually allow to run in defender.
    Works fine

  14. HY i followed all these steps to activate this office 365 and it was succesuful, when i went to open a word doc to see if activated it says that need to be activated! i specify that i install the office in my pc and the original site of Microsoft or office asked for method payment so i can use the 30 days trial of office! but after instalation i procedeed with these steps of activation and even key product entering manually and still says i need a license to activate the office…what shall i do? why in cmd told me was succeful when i opned the word i still need to activate. thanks and wait asap and reply.

    1. This only happen you have more than a copy of Office 365 Program in your PC. Only the without activation office app will pop up for activation.

      Control Panel, uninstall the one you don’t want.

      Done Enjoy.

  15. Sorry but my windows 10 had to be reinstalled and my office 2019 needs to be reinstalled and activated. Please would you send the links again. Is there a way to freely activate the Office 365 version that comes with Windows 10? All this has cost me a great deal of time and also resulted all my old document files being stored on ICloud with loss of recent important document files. I have had to find and restore all my mail codes again as well. Cost of time 3 days!

    Please please let me have a simpler way to do this as my brain is frazzled?

    1. Windows 10 download search on google.

      Office 2019 Top community click in

      Left Hand Side click Others

      My post : about Office 2019

      Download and Installation And Activation show at end of the Post.

  17. Hi, you say that by default, your KMS license will be renewed automatically every 7 days. So you do not have to worry about doing it manually.

    My question is can you not get it to renew automatically every 180 days.

    Many thanks

    1. No.

      renew activation won’t take long time, and nothing to do with your CPU usage etc.

      Just keep your PC or Laptop in 180 days activate status everyth seventh days back to 180 days when you online.

  18. Hello Guang,

    I found you after finding your script to activate Windows 10 online. I saw your URL in there, and followed that to you here. VERY helpful information you provide, very instructive.

    Let me say, I liked your method of activating because to use one of those Windows 10 activators — you never know where they come from or what malware might be lurking in them. With your script, I can see it so I know there is no malware.

    But I’m writing today with a question. Now, don’t misunderstand, as far as I’m concerned, you have been open about things, so I can see your URL in the script. I’m not a coder, so I don’t know what the accompanying code might do with with.

    Allow me to give a bit of background before the question, keep it in context.

    I also saw your information all about doing a similar activation of MS Office 365 2016. In that I saw some talk about the KMS files needing to be updated regularly, and it was said the application must contact a server, I gather a KMS host, for that updating to keep it active. I don’t fully understand this “client” and “host” bit, that is, why both are needed.

    Mind you, I am not the techiest guy out there, this gets beyond me and a little difficult to follow it all. I am not yet even sure I understand what to do with the Office activation, will be getting back to that.

    But to my question that brought you this e-mail.

    Is that URL in your Windows 10 script so the OS can contact your URL to get the KMS files updated regularly? Possibly.

    As I said above, concern about malware was why I preferred your script, but contacting any outside entity raises the concern about malware from that contact. Again, as I said above, you have been open about it, showing the script with the URL in it – that is a positive for you. Still, we are strangers, and the only positive way to know it is safe is to have no outside contact. Then again, maybe there must be, maybe it the nature of KMS, whether with your script, or the KMS activators, which are probably doing similar, although who knows where those are having the OS contact.

    So, I don’t know, knowing the concern, is there anything you can explain to me — maybe the URL is in the script, but there is no contact, or maybe something else.

    Now, secondly, I saw the info in the discussion about Office talking of setting up a KMS Host, I think it was saying that I would be a KMS client. But at first I thought it was talking of me doing both on my computer. So, is it possible to set my own computer up as a KMS host even as I gather it also would be the KMS client? If so, that would avoid any outside contact.

    I don’t even understand KMS, other than that is the method of activation for these, Windows uses that and it must be renewed regularly. I don’t know how those activators work to do it, whether make a contact to some Russian malware provider, or they might do something other than KMS Host to renew the KMS files, or…

    So, that’s the idea. The contact to an outside entity. Is there any reasonable way to avoid that, and if not, is there anything you can explain or tell me that might help alleviate any concern? Other than that you are honest, like I said, you already were open, you didn’t try to slip it through, and that’s what an honest guy does.

    BTW, your script has already been very helpful for a friend of mine, deeply impoverished, who was given a laptop from someone he worked with sometimes who moved to another state. He asked me to help him get some applications on it, but we ran into an immediate problem: they required administrator privileges, and he did not know the password for the administrator on the machine, he only knew the password to get the machine started up, they were not the same. And he had no idea how to get in touch with the guy who had moved away.

    I knew there were KMS activators out there, I told him I would take it home with me and see, letting him know what he would lose by erasing the OS and installing Windows 10 anew. The machine had shipped as Windows 8, had been upgraded. But we were erasing it all, keeping nothing — we could not keep those passwords, so all had to be erased — and that would include the embedded OS serial. And in looking around, I found your script, which sounded perfect and safe (although it was later I noted the URL in it and had this questions for you).

    I installed Windows 10, and activated with your script, it worked beautifully. For certain reasons, I had to reinstall, and I did while keeping the files, and when done, the activation had held. Great. And fully updatable.

    So, I extend you his thank you. (And in his case, security is not an issue.)

    1. For Windows and Office version, update is from Microsoft like retail version.

      Activation will automatic renew back to 180 days every seventh day when you browsing internet.

      Connect to Mr Guang server only for activation, no harm to your PC or Laptop.


      1. OK, so it will connect to that server every 7 days.

        And is there no way to do this without connecting?

        Is this how al the activators out there do it, but to their server?

        Thank you.

    2. Without connecting, meant without update activation.

      The only way not connect kms Server is disconnect form internet.

      Universities, Public Hospitals, Libraries etc, is very common use KMS Server method for the staffs or students to use Windows and Office in PC and Laptop. Activation must connect to their KMS Server to renew.

      1. So what if I dont want to be connecting to a server anymore and want the license key to run out can I not do that?

        1. Kms activation will automatic renew back to 180 days when you online.

          You will browsing internet every day, so it is not the way to stop using KMS Activation.

          Top serach: Uninstall Microsoft product trial license or KMS license completely

          Uninstall the KMS Activation key first, control panel , uninstall the Office Program or Windows Program attached KMS Activation. Or get a retail key to activate Office Program or Windows Program again.


          1. Thank you for your efforts. But my question is, what if you aren’t connected online on the seventh day,does it expire?. Again how long does it take to fully activate the windows automatically on the seventh day.
