When you speak of upgrading "my Dell computer", you're not speaking of installing an upgrade over top of XP are you? If so, I misunderstand, so disregard the rest of my post. :) So I'm assuming you intend to purchase a retail version of Windows 7 and do a clean install. In the first line of your post you mention 512 MB of RAM, a date, and then 2.00 GB of RAM. Does that mean it now has 2.00 GB of RAM or maybe 2 1/2 GB of RAM? Either way, I'm no expert but I'd think 512 MB is less than enough, but either 2 or 2 1/2 GB would be fine. I don't know much about Office, but wasn't Office 2003 was the last version that had the old style menu, before the newfangled ribbon came along. According to this, your Office 2002 would not be compatible but according to this, Office 2003 would be. Would your 2002 macros work in 2003? I don't know. Would it be worth the expense of buying a retail version of Windows 7, as well as Office 2003(or at least Word)? To me, probably not, to you, only you can decide. Personally, since it works, I'd probably just continue using it. Continue running a good real-time AV, occasionally scanning with a couple on-demand malware tools(Malwarebytes and SuperAntiSpyware come to mind), use Firefox or Chrome(lie detected), using the WOT add-on(trusting it somewhat less than fully), and being careful what I open(email) and what I install. Just my opinion though. Edit: GrammerGrammar Edit2: Spelling This post was edited by chuggerguy on Thu, Jan 23, 14 at 3:10

The Marvins are normally cheaper than the 400s around here. The 400 is a solidly built window in my opinion. Depending on what you are needing, there are options beyond just those you mentioned and perhaps they might be worth looking into.

She doesn't know glass technology too well here. They won't help you reduce heat gain by any real significant measure. All they will do is make the glass darker. Between lamination (eliminates any UV ray transmission) and Low-e III (reduces the SHGC significantly), you are in good shape.

What does the error say when you try and connect to Google for instance ? Have you seen this scroll down a bit to the last post, http://www.tenforums.com/network-sharing/43934-win-10-wifi-problem-dell-3521-a.html
