user69754: I downloaded bitcoin core, and it "synced" the blockchain, taking up 163gig on my HD considerably slowing my comp. so I uninstalled bitcoin core, but yet still see to have 163gig of unwanted data slowing my computer. I operate Windows 10. HOW do I get rid of it. It seems to be in my users file, but mysteriously doesn't show up when trying to locate it? 

user9822: You need to delete your data directory.
See the question Where is the data folder for Bitcoin-Qt? for where it should be installed by default on your system.
Make sure you backup wallet.dat first, if you've ever used any of the addresses in your wallet.
