My Acer Aspire 3055 WXMI keep asking for 25-character product key number. I cannot find it anywhere. It’s not on a menu. Can you help please?
Locating the Windows Product Key Label
Since you have a laptop, finding the product key may be as simple as flipping the computer over and locating the Windows sticker on the laptop’s bottom. Look for a Windows “Proof of License” or “Certificate of Authenticity” label on the bottom of the laptop. If you had a desktop computer, you would look for this label on the computer case. The Windows proof of purchase label will have a bar code as well as the 25-digit product key for your copy of Windows. Unfortunately with laptops, this label does get worn as it rubs against various surfaces such as laps. If you can’t read the print, you’ll need to look elsewhere.
Did you save all the original discs and documentation that came with your computer? The original Windows installation disc should also have this information affixed to it. In fact, your Windows installation disc may be sealed in a package with a license clearly visible. Likewise, if you purchased Windows on a disc and installed it on your computer, then the label will be on the CD case.
Locating the Windows Product Key from within Windows
Since Windows is prompting you to activate it or to enter the product key, this next method may not work. However, it’s worth a try. If you have Windows Vista, go to the Control Panel and click on the System icon. Scroll down to the bottom where you will see the Windows product key. Write this number down, especially if you ever need to reinstall Windows and the proof of license label is worn off. If the product key in this screen contains the letters “OEM,” it is a generic product key installed by the manufacturer. In this case, the generic product key cannot be used upon a reinstall of Windows.
Using Software to Retrieve your Windows Product Key
Magic Jelly Bean’s Keyfinder software is an open source product that will find the product key from within Windows (all versions from Windows 95 through Vista) as well as for any of your Microsoft Office products. Again, if Windows was installed at the factory, a generic product key may be retrieved which won’t necessarily help with a reinstall.
