How to find Windows 7 product key on my pc?

f you no longer have the original packaging, physical sticker, or email confirmation, the product key is still stored within the Windows registry. While it's not possible to easily locate the key by browsing the registry manually, you can retrieve it using special software that decodes the encrypted key stored in the system. 

How to find Windows 7 product key in registry:

1. Press Win + R to open the Run dialog, then type regedit and press Enter.

2. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

3. Look for the entry named DigitalProductId. This is where Windows stores your product key in an encrypted format.

However, this method will not give you a readable key without using a decryption tool like the ones mentioned earlier.
