Lyn After your email this afternoon, you piqued my interest--BIG time. I've spent the last few hours trying to get an answer on this, and it's turning into a nightmare. The more I find out, the less I like what I'm finding!! OK. Here's the sum total of what I've found out and been able to deduce from those findings thus far:- 1. As you suspected, every time you visit a site, a key gets added to the registry. The main reason for this is that the site coders are working on the assumption that you'll either take out a subscription to the site, or bookmark it for a revisit (for whatever reason). One rider I have figgered out MUST be taking place is that site affiliates of the original site are also adding registry keys (hence the reason you're finding keys to sites you've never heard of). There's no other way to explain what's going on. I'd have serious words with your Internet Service Provider about their security settings. 2. I'm running a dual boot system here, with Win98SE being connected to the web and Win2K not. Would you believe I found MORE of these keys in the Win2K side than I did in the Win98SE side. Go figure!!! 3. On the above basis, it SHOULD be OK to delete 98% of these, but I'd advise extreme caution here. Deleting keys willy-nilly from the registry is NEVER a good idea--all sorts of ramifications could result. I'd strongly advise backing up your bookmarks for a start, and then using them to reinstate sites you ARE intersted in. Also, be aware this could impact on software you're currently running. If (for instance) you're running ad-supported shareware on your system and you delete the keys those ads require...... 4. There are registry tools aplenty out on the Web which should be able to help you with this, from Hijack This (designed for a totally different job, but useful here in that you'll get access to keys which the "normal" tools might hide from you), to heavyweight beasts like Registry Medic. Most of these are (surprise surprise) commercial, but you should be able to get trial versions to at least let you see what's going on. As you can gather from the above, this is an area fraught with pitfalls. You may be able to find a commercial outfit locally willing to undertake this service for you, but bear in mind that their normal way of dealing with things like this is simply to delete the lot. It's up to you whether this would be a viable out (though I somehow doubt it). I'd advise reading up on everything you can lay hands on on the Registry (even if it's only help files of the various utilities out there). It's surprising just how much valuable information is hidden in those files. Good luck with this one--and many thanks for pointing it up. It's something I'll certainly be keeping a much closer eye on from here on out. Hope This Helps Geo. Geo.
