I want to restore to my previous Product key which I had lost, is there any way to restore previous product key to activate my laptop's windows

If you have lost the key then you may have to clean install Windows.
Which version of Windows are you using?

You need to have the product key in order to enter it and it must be for the same edition.

Click Start > Settings > Update & security > Activation > Change the product key then enter the new product key then click Next to Activate

If you can't find the key, you will need to purchase a new key.

Also, see how you can find your original key:

Can’t guarantee this will work but as you have a genuine key for Pro you could try entering the generic key to see if it’ll activate.

If this doesn’t work then it’ll require a clean install imo.
