I have a unique situation. I have a PC with Windows 10 Pro installed. I replaced my harddrive and installed Windows 10 as a completely new installation. After doing my configuration, I did all the Windows updates. Finally, I did the updates in the Microsoft Store. What happened was, that in the item list, applications that I had downloaded from my previous installation were listed as acquired and purchased. The trouble is I never logged into my Microsoft account. The purchases were free downloads so not real purchases, I understand they are just listed like that. So what I would eventually like to do is sell my computer. I don't want my Windows installation to list my old applications and etc. So how can I clear my pc completely? One thing I researched was the key associated with the BIOS. I understand it's unique to the PC the Windows is installed in. So I figured, I would try a new purchase of Windows. So I purchased Windows 10 Home Edition and when I installed it, all those apps showed up in the Microsoft store again. This is ridiculous. How can you alter that. Can I manually change the key and install it again? If yes, can I just retrieve the activation key, change the BIOS key and reinstall with it like that? Before I try again, I wanted to see if someone has expert experience with this. I am new here, but heard there are alot of pro users in this forum. Any advice would be nice.
