Dell inspiron 15 5577 is the worst laptop ever created

Right out of the box this thing is slow as ***. Its slower than a 10 year old laptop. Its like its running on a pentium 4 or something. I tried almost everything and it still super slow. What a complete waste of money. I can't believe they shipped this without testing if it even works. I wanted to try and swap the hdd out for an ssd but guess what? No product key and no disk so I can't easily do that. I am litterally blown away by the crappiness of this laptop. I have never encountered something like this with any laptop ever. Even a *** dell mini 10 runs faster than this piece of ***.
