I used the linked file, DelDomains.inf, on a machine with fully updated Windows Vista Home Premium and Internet Explorer 8 production version, and it solved the slow IE8 startup. 2009-03-24.

This file did the trick!
I was waiting for this simple yet effective solution!
Thanks a lot!

Works Great!
Thanks

Until now IE8 opens in a few seconds. Now in half a second. If I need more screens I always open the program separate more times. Also the separate screens opens in half a second now. Faster as IE7.
A GREAT, GOLDEN tip.

This did the trick, although I’m a little skeptical considering I don’t really understand what it did exactly. More information would be helpful.

OMG, thanks so much. I have been struggling with this problem with IE8 ever since installing it. Not only would IE8 hang for up to 15 seconds, it was causing other programs that access the internet to hang, e.g. Malwarebytes would hang for 15 seconds when updating before it actually updated. It works perfectly now after removing all of the restricted sites. I love you.

[...] Ahhhhh, after literally 8+ hours over two nights trying to figure this out, I found this page: http://windowsfixup.com/2009/03/spee…et-explorer-8/ which has a utility to delete all of the restricted sites that Spywareblaster, Spybot S-D and [...]

OMG OMG THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I really dont need to know what this install did, just the fact that it’s FIXED my ie8 slow problems!
Not only was ie8 taking UPTO 30 secs to load for me, but even my pics/ my docs was taking sometime to fully load up.
This has done the trick 100%, cannot thank you guys enough!!

thanks a lot

this file did the trick thanks a lot

SUPERB. Almost instantaneous now. Much faster than FF.

To me, this “fix” appears to remove one of the biggest security features of IE8. I would seriously think about before installing this “fix”.

Hi,

It’s a nice and a simple fix. Thanks for the fix.

Faster…although i thought it was even fast before in ie7

Although this solves some start up and browsing issues, it doesn’t solve the sluggishness of the IE8 UI, that can be solved with a different method.
Start>search “CMD”>Right click cmd.exe and click “Run as Administrator”>type (without quotes) “regsvr32 actxprxy.dll”.

actxprxy.dll is a file that’s supposed to be registered in the registry during the installation but for some reason is commonly left behind, re-registering it has no benefits but also no cons, so you really have nothing to lose by trying it. IE8 has a hard time working at all without it. These instructions are for Vista/Win7 only btw.

I cannot believe it ! My computer is like new again. IE8 works so well and quick.
Thanks

the install failed on my Vista Ultimate machine. What could be the problem?

Excellent! WHat a difference on my Vista machine! Thanks!

It just blinked for a second and didn’t advise if complete. Is that Right? Also, in the program itself (in Notepad) it says to run in Explorer! I’m ignoring that and runing off hard drive, right?

made no difference tabs still take 15 to 20 seconds to open

This tweak removes all of the restricted sites/domain names that SpyBot, Ad-Aware, etc., store in IE to prevent access to them by the browser. That is why you use those programs. There are thousands of names and it takes a bit to load them into memory.
If you run this tweak then be sure that you Turn ON the SmartScreen filter under Tools in IE8. A good discussion about it is here http://blogs.msdn.com/ie/archive/2009/03/25/ie8-security-part-ix-anti-malware-protection-with-ie8-s-smartscreen-filter.aspx sorry, can’t figure out how to do a hyperlink in here).
It will take a big leap of faith to bypass SpyBOT and Ad-Aware … I have used them for years.

the install failed on my Vista Ultimate machine too. What could be the problem?

I did this install a few weeks ago and it worked great. I’m using IE8 a lot more now. It was a dog before. I installed and unistalled about 3-4 times. Thanks for the great fix.

DelDomains worked great. I had previously tried registering actxprxy.dll, but that didn’t do anything. I’m running Dell D520 laptop with XP SP3; Spybot; COMODO; ESET NOD32. I had previously tried IE8 and because of the speed issue, went back to IE7. Now, IE8 is right up there with IE7 — I guess I’ll keep IE8.

Worked great on 2 desktops, but when I try on a Lenovo laptop I get an error, the Microsoft IE has encontered an error, to send report……

ANy ideas?

Great tools! it works great for my Xp! Thanks

i was a touch skeptical, but this really made a difference both with opening new windows and with page rendering speed. opening new tabs still leave much to desired (i really dont understand why that particular function is so damn slow), but it is better than it was. thanks!

Worked also for XP! Thanks!
On ewonders why the heck Microsoft didn’t understand that this would cause a lot of anger amnoing the users… Time to switch browser, finally?

Hey guys. Great web site, and simple solution – but for me, it did not work. I tried both options described (installing the INF and running the command prompt option). IE 8.0 still takes about 15 seconds to load (same as before), and same to open a new tab or new window. Any other thoughts? Would love to be a test case. I run Vista, all updates are current. I use Firefox currently, because IE 8.0 is SO SLOW. I ran 7.0 before, and it worked like a charm. Also, noticed 8.0 doesn’t often recognize Adobe Flash is installed. It is, and works fine at the Adobe site, but most sites say it is not installed. The same sites work fine in Firefox.

Sorry but I put the file DelDomains.inf on my Vista Desktop but when I right-click i get not option to INSTALL.

Any ideas???

OK I fixed it without using the DelDomains.

Open IE8
Tools
Internet Options
Advanced (tab)
Click Restore Advanced Settings
when that is done
Click Reset for good measure.

This cleared up my problems.

Note however that Firefox is still faster…..

Thanks heaps worked a treat

FYI. I had the same problem on Windows 7 RC 64-bit. This method did not work. But uninstalling an old Java version did the trick.

IE 8 install had some very unexpected effects on two XP pro machines. It slowed the speed at which all windows on my system close, not just IE. Now when I close any window it does not just disapeare from the screen. It fades line by line from top to bottom, the way windows used to close on the most ancient slow PCs. It does not take long about a second but that is forever in terms a screen video artifact. Has anyone seen this issue?

Did the regedit thing and all sorted. Great!

Neither of the two fixes worked, it loaded even slower and tabs were slower. Lavalie’s fix, 5th June, worked a treat!! Thanks it was driving me insaner than I normally am.

The issue with IE 8 is tis, as of the time of this post there have been reports of IE 8 running very slow after installing Spybot.

It worked for me. Thank you so much for the fix

Sir,

When I right click the link and save on the desktop, I get a text file DelDomain.txt which cannot be installed. Where can I download the file?

lavallie’s suggestion did the trick! I also agree that firefox is still faster but IE8 improved so much. Thanks lavallie! I copied lavallie’s post below so you don’t have to go seraching for it.

In addition to the above solution u can also disable all the add ons from the Internet options-> Programs tab-> Manage addons button.
For me skype addons were slowing up IE.

Many thanks for the fix which worked a treat, and also for putting it in a language I can actually follow instead of “tech speak” as some sites tend to do.

Have had this problem for just a few weeks after downloading IE8 onto WinXP SP3 and it was driving me nuts.
How some of you people have managed with the hassle for so long without attacking your PC with a sledge hammer is beyond me lol!
Thanks again, Absolutely Brilliant Fix!

Wow. Worked for me. I use Firefox mostly, but have to use IE because a few work programs require it. It has been an unbelievably frustrating experience to date. Then I found your website. Home run.

Thanx for the tips.it helps a lot.To make IE8 more responsive loading time,i just turn off smartscreen filter and disable animation in webpages.

I thought this was going to be another thing to “F” up my computer…this joint works!!!!

The DelDomains.inf file download thing worked out best for me.

Everything is working the way IE 6 and 7 was in terms of speed.

They need to update IE 8 with this fix and stop having people think that the slowness is just their computer or ISP.

I am on cable modem and before couldn’t believe how slow my web pages were loading that I called Time Warner pissed off at them (Sorry ’bout that guys, Road Runner still rocks!)

I can’t thank you guys enough for having a solution that actually works and the results pretty much immediate.

Take care!

This DelDomains.inf don’t help !
IE8 still don’t start …
I must return to IE 7 ?

Project Server on portal is too slow on IE8…

i cant find this CMD file i ran the deldomains … do i need to restart computer?? i am runing xp IE 8 and it is still slow to open pages within a site i am slow also???? help me please

Para indicarles que despues de la última actualización del internet explorer, no hace falta quitar o depurar el archivo dll al instlar Deldomains.inf.

La recomendación es restaurar el internet explorer, seguir la siguiente ruta:

1. Herramientas.
2. Opciones de internet.
3. Opciones avanzadas.
4. Boton: restablecer.
5. Terminado el proceso de restablecer se reinicia el internet explorer 8.
6. Se reconfigura las opciones de acceso de internet.
7. Durante este proceso se puede deshabilitar Vista de compatibilidad y la opcion de Smart screem.

Listo!

this tricks dosent works at all !! best way to sort this out go to services and look for services that already began but manual change them to automatic. your browser will load in 4 second

bon pour moi merci beucoup “French”

Freed up my IE8! Thanks for a simple solution to the frustrating nightmare!

could not find file cmd.exe ? What does that mean if I can’t find it?

Tried everything to fix IE8 but nothing worked. I am sick it, its crap.

I am now using Google Chrome – much faster. I won’t be going back to IE.

Excellent! Solved the problem – Thanks.
