How To Manually Reset Windows 7 Product Key Information

There are times when for whatever reason your Windows 7 installation may become unregistered and begin warning you that you may have a pirated version of Windows installed on your computer. You may have purchased your computer from a major manufacturer like Dell, HP or others that swear to you that pirating isn’t the case. So what is it you should do to fix this?

5 Steps To Reset Windows 7 Product Key Information

Step 1

Open a command prompt window as Administrator. There are several ways to do this in Windows. The way that I usually do this is:

click the start menu Windows 7 Start Menu ball and type cmd without pressing enter in the search box asĀ  demonstrated below the Command Prompt option will show up in a list. Right click on the Command Prompt option and select Run As Administrator in the context menu.Right click on the Command Prompt option and select Run As Administrator in the context menu.

Open Command Prompt
Open command prompt as administrator

Step 2

The next step is to type slmgr /upk press enter and wait for this process to complete. This process uninstalls any current product key that may be in place and put Windows back to an unlicensed state.

Step 3

Once the above process has completed type slmgr /cpky at the command prompt press enter and wait for this process to complete. This process will remove any Windows product key from the registry if it still exists.

Step 4

Once the previous process has completed then type slmgr /rearm in the command prompt and press enter. Once this process is complete the Windows activation timers should be reset and a window informing you that you should restart Windows will appear.

Step 5

The final step is to restart your Windows 7 machine. This will allow Windows 7 to restart as though it had never been registered and a window prompting you for your Windows Product Key should appear.

Acting Like Windows Was Never Activated

Once Windows starts back up you should now be seeing a box telling you that Windows needs to be Activated. Your Windows should be as though it had never been activated before.

The next step is to activate Window with your Product Key. If you have a computer that is from a Manufacturer like HP, Dell or the others then the registration key should be located on the computer itself. If it is a laptop and you can not find the Product Key sticker be sure to check under the battery.

Whether you are using an existing or a new product key simply go through the activation process regularly and your Windows Key should now work.

For Whatever Reason

Like I said at the beginning sometimes this can happen for whatever reason. Sometimes a registry key entry may become corrupted, malware or viruses may alter critical information. You may have even gotten a computer whose registration key was used by someone else. There are endless reasons both innocent and not so innocent that Windows registration problems can happen.

Recent Microsoft updates have made the Product key check from Microsoft much more accurate and stringent so if there were questionable ways that your product key had been obtained this can also be a reason to waking up to a computer that is no longer activated.

No matter what the reasons behind the problem using the above method with a valid Registration key should fix the problem and have your Windows 7 back up and running normal again.
