Windows 7: IE8 slow? Maybe this tweak will help

IE8 slow? Maybe this tweak will help

actxprxy.dll is one of the core libraries for Internet Explorer (along with a few others such as Urlmon.dll and Mshtml.dll). If it’s not properly registered, IE won’t work at all. And re-registering it should never be necessary except in extreme circumstances.

Heres how to register it:

1. Open cmd prompt (winkey+r then type cmd and run it),
2. enter regsvr32 actxprxy.dll
3. reboot

It would be interesting to see if this tweak speeds things up for you.

Win 7 Ult SP1/Win 10 Pro (all x64)

Go to Start/All Programs/Accessories, right-click Command Prompt and "Run as Administrator".

Swarfega, it seems to have worked here. Not a huge speedup but some...I think!!

Now to test it in Vista and XP.

Vista and now 7 in 32 and 64 bit.

Believe it or not. I have a little list if hints and tips, which slowly gets added too. I have that , from 2004, as a tweak for IE5 !!

Perhaps this page will interest anyone who wants to try it. This guy usually gets it right.
