I currently run Microsoft Windows Vista Business, with Internet Explorer 7 (7.0.6001.18000). I’ve been using IE7 since its beta stage (on Windows XP to begin with) and have never had this problem… After I upgraded to Windows Vista, I’ve noticed serious memory leak / problems with the browser.
IE has been running for about 3 hours. In total, I’ve opened (and closed) between 30 - 40 tabs. Then suddenly, when inspired to check the news online, my computer started to feel extremely sluggish… So I opened up task manager, expecting to see IE7 eating up all my resources as I’ve seen before. And that’s exactly what I found.

Good lord, what is going on? So I closed IE, and waited several seconds for the system to free up some memory. Then restarted IE7 to write this entry.
As far as I can see, it seems to be a problem with AJAX (as I’ve noticed IE7 feasting on my memory most often after I’ve been on Facebook and other AJAX websites), and after some digging, found:
http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=105535, which seems to be a bug Microsoft refuses to address. I have also tried running IE in safe mode, or without any add-ons but to no avail.
Speaking of which, I currently have one IE7 window opened, running for less than 20 minutes with 6 tabs running… And memory usage has jumped to 144MB. What?!
I really do want to stick with IE7, and doubt I’ll ever fully convert to an alternative such as Firefox, as it’s just not to my taste. I don’t wish to turn this post into a IE7 vs. Firefox debate, but am really needing a solution!
So, has anyone else found they also have this problem? I would love to hear any advice anyone has on fixing this!
