My Computer is So Slow

I do not know why this has been happening recently, but my computer has been so slow lately. I have to admit that I might be the culprit here and I might be the one to blame for the whole situation. I have been installing a lot of programs lately and those programs probably clogged my PC a lot. One solution to the problem would be to start removing some or even all of those programs, but another solution is going to be to do something completely different than that like using some tools for example. I do not know yet what I am going to do about it yet, but I am going to do something for sure.
