In an effort to teach myself more about my computer I have come across and downloaded The Tweakguides Tweaking Companion and it seems to be a very good source of information. I guess I'm just asking for confirmation from you guys (the experts) if I'm on the right track. Is it something I can befefit from?
I didn't think about it, but CJ is right. I have seen some huge screwups, especially with "fix you computer automatically" software like CCleaner, RegCleanNow, GlarySoft, etc. in fact, there is a thread dedicated to ripping them somewhere in the geeks lounge.
A couple of little recommends though:
some of my clients quite like the folowwing bits of software: iobit (only use the defrag and gamebooster utils, and I haven't looked at any of the other tools for a while, because they were in early dev at the time, and not very good. Maybe worth a revisit now. I use ESET SS for my AV products, yes I am affiliated with ESET as a Qualified Vendor, Reseller, and Certified Admin/Deployment. But only because I believe in the product. Just to clear up any confusion.) Stardock's Fences
Thanks to everyone for all their good advice. I will be very cautious when tweaking but I'm finding this guide (Tweakingguide Tweaking Companion) very useful as a "user's manual" as it's filled with everything you always wanted to know about Windows XP.
