How to remove the wired key in the bios. How to find OEM Windows Activation Key from BIOS
In today's article, we will explore the issue of how to find out serial number Windows, which was pre-installed on your equipment upon purchase.
Recently, Microsoft has changed the way they license their OEM products, namely Microsoft Windows. We are talking about those types of licenses that are usually pre-installed on laptops and system blocks manufacturer or assemblers, namely OEM licenses, developer licenses and single language versions.
Previously, when you bought a laptop with Windows 7 installed, you could find a sticker on the back of the equipment with the name of the purchased license and its activation key, which usually consisted of 25 characters. But since the release of Windows 8, the methods of distributing licenses have changed and now on the back of your laptop you will find only the Microsoft branded label, which confirms the right to use the operating system. Neither the name of the license nor the key will be on the sticker!
Why is that? The thing is that with the advent of the UEFI BIOS, it became possible to sew the key directly into it, and the system is activated automatically, without manually entering the key, provided that the laptop has exactly the edition of the operating system for which the serial number is preinstalled. Those. If you bought a Windows 8 laptop with a single language license and then upgraded to Windows 8 Professional, then your copy of Windows will not be activated.
- Contact service technical support equipment manufacturer. It will take a lot of time and will cost a lot of money. In addition, you will receive a clean operating system with basic settings and you will definitely lose all personal information.
- Use regular resources Windows Recovery. In this case, you simply roll back your system to its original state from the copy that is stored on the “invisible” partition of your hard drive unless you delete it.
This method is more likely designed for novice users, but not very convenient in practice. The thing is that when the system rolls back, the user gets the original preset a copy of Windows, with all previously installed demo programs, proprietary utilities and other rubbish that clogs the system and in most cases, an ordinary, and even an advanced user, will never come in handy. You will also not be able to change the hard disk partitions as it would be more convenient for you during recovery.
In addition, you must copy your personal data and settings to external storage in advance, otherwise you will lose them. This also brings some inconvenience.
If for various reasons you do not want to carry out these operations yourself, then we are ready to offer you our assistance in installing the operating system on your equipment. Check out our website!
- What if the recovery partition does not exist, or recovery from it is impossible for various reasons? In this case, you will need to download the distribution kit of the operating system that is associated with your purchased license. Next, you need to write it to DVD disc or create bootable flash drive, then perform a clean installation of the operating system.
But the difficulty is that Microsoft has not officially published its distributions for download for a long time and finding the edition of Windows you need can cause problems, and downloading various modified pirated assemblies is also wrong. Another disadvantage in this approach is the problem with primary activation after clean install. Windows for various reasons, despite the fact that the assembly is selected correctly, may not want to go through activation.
How to get a Windows license key on a laptop
That is why we will need to extract the license key from the BIOS in order to activate the system manually via the Internet or by phone. To do this, we need to open the command line: Start > Run > cmd.exe
In the window that appears, run the command:
wmic path softwarelicensingservice get oa3xoriginalproductkey
So, it so happened that you have to reinstall windows (hdd, bsod, other problems die ...) and next to the problem there is a desire to transfer an honestly acquired license. But here's the bad luck: the sticker was erased, the record was not preserved, but what did I care? Yet it worked! There is a way out, but with Windows 8 , 8.1 and 10 even easier, there the key is sewn into the bios. Microsoft uses a 25-digit code, which is what we need. I'll tell you about three relatively simple ways find out the product key: software, using a script and wired into the BIOS, let's go:
ProduKey, a time-tested program, shows keys for Windows, MS-Office, SQL Server. Just download and run the .exe file from the archive in a couple of seconds, you're done.
Using this utility, you can not only look at the key on installed system but also for example from an external device ( external drive, usb flash drive) or connect a disk with a second system. It happens that Windows does not start due to disk damage or blue screen this is to blame, but it is necessary to find out the key, then Product KeyFinder perfect solution.
Download, install. Run as administrator.
Click the tab Tools, and then Load Hive…

Choose on external device Windows folder and press Enter. After a few seconds of scanning, we get the system version and the key for installation on new disk clean Windows.
2. With a script
A method for seekers, it is a little more complicated, but more interesting.
Set WshShell = CreateObject("WScript.Shell") regKey = "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\" DigitalProductId = WshShell.RegRead(regKey & "DigitalProductId") Win8ProductName = "Windows Product Name: " & WshShell.RegRead (regKey & "ProductName") & vbNewLine Win8ProductID = "Windows Product ID: " & WshShell.RegRead(regKey & "ProductID") & vbNewLine Win8ProductKey = ConvertToKey(DigitalProductId) strProductKey ="Windows 8 Key: " & Win8ProductKey Win8ProductID = Win8ProductName & Win8ProductID & strProductKey MsgBox(Win8ProductKey) MsgBox(Win8ProductID) Function ConvertToKey(regKey) Const KeyOffset = 52 isWin8 = (regKey(66) \ 6) And 1 regKey(66) = (regKey(66) And &HF7) Or ((isWin8 And 2) * 4) j = 24 Chars = "BCDFGHJKMPQRTVWXY2346789" Do Cur = 0 y = 14 Do Cur = Cur * 256 Cur = regKey(y + KeyOffset) + Cur regKey(y + KeyOffset) = (Cur \ 24) Cur = Cur Mod 24 y = y -1 Loop While y >= 0 j = j -1 winKeyOutput = Mid(Chars, Cur + 1, 1) & winKeyOutput Last = Cur Loop While j >= 0 If (is Win8 = 1) Then keypart1 = Mid(winKeyOutput, 2, Last) insert = "N" winKeyOutput = Replace(winKeyOutput, keypart1, keypart1 & insert, 2, 1, 0) If Last = 0 Then winKeyOutput = insert & winKeyOutput End If a = Mid(winKeyOutput, 1, 5) b = Mid(winKeyOutput, 6, 5) c = Mid(winKeyOutput, 11, 5) d = Mid(winKeyOutput, 16, 5) e = Mid(winKeyOutput, 21, 5) ConvertToKey = a & "-" & b & "-" & c & "-" & d & "-" & e End Function
Create a normal Text Document .txt open it and paste this text there:
Change the file extension from .txt on the .vbs and run the script, after a couple of seconds we see the key. Who is too lazy to do manipulations, download the finished script.
3. Pull the key out of BIOS (bios)
This method is real hardcore, it will help you find out the key of all windows wired into bios. AT latest versions computers preinstalled with Windows 8, 8.1, 10 do not have a sticker with a key, of course you can find it above listed ways, but what if you put another version or Linux on top, for example? The key is stored in the bios chip, and on the one hand, it's great, you won't lose it, and if you want to know it, use RWeverything.

Hello dear readers. Do you know how to activate licensed Windows correctly? Say what you know, hmm, I thought so too, but somehow I got a laptop in my hands, on which, after installation new Windows 8, I was going to activate it with the key, but to my surprise, I couldn’t do it. To be more precise, after clicking on the "Activate Windows" button, instead of a prompt to enter a key, incomprehensible errors appeared, such as this one: "DNS name is not specified."
Over time, of course, I figured out what was wrong, it turned out that during the installation of the system, some incomprehensible key was picked up, which at the time of activation was simply not recognized by the system.

Well, okay, I thought, maybe the computer automatically substituted the necessary activation key itself. But just a moment later, an error appeared, which I wrote about a little higher. All subsequent attempts to activate Windows were unchanged, except that the error code changed.
Well, I thought and tried to find a field in which it would be possible to specify the key that I got from the BIOS, but instead some incomprehensible key was already indicated everywhere. I could only see a few characters, but it was enough to understand that given code didn't match what I had. Thinking that there was some kind of confusion with activation keys, I decided to delete old key and re-enter a new one.
In general, after I deleted the old activation key and re-led the one that I prepared, everything worked out for me. At first I saw the word "Success!!!", but then what Windows activation completed.
