I make my initial inquiry at
http://gladiator-antivirus.com/forum/index...mp;#entry162001
Based on advice in that thread, I downloaded CCleaner AND REGCLEANER, and followed some links, to learn that regcleaner is no longer supported. I joined the forum which REGCLEANER mentioned
http://www.macecraft.com/phpBB2/index.php
and learned that jv16powertools and REGSUPREME are the current programs which correspont to REGCLEANER.
There are technicians who still use REGCLEANER and say it works very well, but it is no longer supported by the author.
Anyway, since I am a beginner, who desires to learn about backingup, modifying and restoring the registry, it occurs to me to purchase a very cheap machine, and windows xp, so that I can install and reinstall and ruin the machine as often as I please, with no inconvenience or loss.
REGARDING CCleaner, how knowledgable to I need to be to use it without harming my computer? I have windows xp on a Dell.
Thanks!
