如果你的Windows 7是从Microsoft那里得来的话,你就可以从Windows 7 free upgrade to Windows 7,但是你要激活你的Windows (如果你把原先的OS cloned to another one),那么你要再次激活clonded Windows 10 using the key that you installed Windows 7. However you may have difficulty to find the old installation key anymore since you are not able to find the box or label. However you may use the third part program to extract the original key for installing Windows 7. For example using the following program

The above one does not require you to install to extract the Windows key from the Windows registry folder.

Apart from the above method, there are many others shown below:
