Can I get windows product key after reinstalling windows by my own?

Bhism

I have recently bought this laptop. I had to reinstall the pre-installed windows on this pc someway or other. But, I didn't noted the product key of windows. Now, present windows of mine is not activated, it is asking for product key. Is there any solution to get official product key of windows which is given by acer swift itself?

I also lost MS Office. Can I get that again?

If your laptop has preinstalled Windows, OEM version, the key will remain with the hardware, and if you install the same version, it will activate automatically. No product key required. MS365 (Office) is a subscription platform that you need to renew yearly, you can reinstall the 1-year free subscription online from the Microsoft store. I recommend that you get Office Home and Student 2021 license for life for <$130, look for a promo but be aware of pirated/hacked product keys.

If you had an Office license, then just logging back into your Microsoft account will allow you to continue to use it.
