I know this doesnt belong here, i apologize. my sister is trying to get on caissa with her computer she bought in '02. She gets a message you seem to be using an older version of windows explorer and shure enough she times out. I have heard that there are two versions of windows, 1) VISTA and 2) #7.
I have heard that VISTA may have some bugs and they rushed with its production. Windows #7 is more modern and seems to be the more reliable. The way you update is by getting the disk, say for windows #7 and then as if by majic you have a more recent version, and are good to go. I would like to know if I am in the ballpark with this summary and if anyone cares to, to add any necassary refinements that might make a version update all that more complete. Thanks for your help.

Vista will work. I an using it now. Sometimes the site needs an older version of Java. I suggest using Firefox, it is a free download.

Thanks very much RAPTOR!

This post has one final addition, you see everybody at work says I have to "get the disk" to update, now at my local library, the librarian said, " you have to go to the windows website", and you can update your windows online. Is one or the other correct, or is it that both are correct????!!!!Thanks for any help!

Update vs. Upgrade
 
Just a tad bit confused. I think both are correct however:
 
1.. Do you want to “update” your existing operating system?
IE: get the latest so called fixes for you exiting system.
 
If so this is free. Using Vista, which I have, go the control panel and locate the item “Windows Update” click on it and it will probably says something like 3 important and 9 thousand optional (just kidding) Click on download and it will say a few minutes which really means about 19 Bill Gates minutes to complete then process.
 
2.. Do you want to "upgrade” (change)to a different operating system like Windows 7? Yes you will need the upgrade disk or download from MS site?
 
Upgrade to Windows 7 (download)will cost $119.99 through the MS site.
 
Upgrade to Windows 7 Home Premium through ebay is about $50 to $70 for the disk. Be careful to get the genuine disk with certificate of authenticity (COA) with the deal.
 
 
Or just do what I did and go to the Dell site and buy one of the $400 laptops with Win 7 on it. Now the Starbucks crowd can laugh at my stupid moves in g5 and g10 games.

thanks RAPTOR for making this all a little easier to sort out, im not sure but I think the message was we were using an old version of windows explorer and would experience formatting problems. i asked the librarian what windows they were using and they said "VISTA" cause when I get on caissa at the library, there is never any problem, meaning that it never "times out".
