Every time you run your computer it  54   to carry out these instructions but, because the related program can't be found, it causes a registry error.  Your PC is doing a lot  55   work than it should be and the result is a significantly  56   computer.

  One of the best ways to manage this is with a   57   little tool. This program scans, identifies and   58  registry errors - resulting in a computer that's a lot more like it was when you  59  bought it.
