I recently changed several settings, in a command window I now can't locate, that had to do with how my computer communicates with other computers, servers, etc.
Senseless, since I don't network, develop or game, but they seemed like good things to initialize, so I did.
I fancy myself more knowledgeable than I am, thinking common sense instead of real knowledge.
Now I get painfully slow re-boot, app startup, page load, even execution of simple clickable commands, and the worst is that I am constantly getting (Not Responding) errors on virtually every application I use, especially Firefox!
Now, rather than learning my lesson, I'm tempted to disable things like ASLDR to try to speed things up, choosing to gleek my way into wrong-headed fixes instead of going back and undoing the damage!
Sorry I can't be more informative about what I changed, but I can't for the life of me find the options window where I opened all these tree branches and enabled all these protocols!!!
