IE8 setup flaw

There seems to be a serious problem in the IE8 setup process. I've noticed
the following:
- after installing IE8 on an existing Win2008 x64 virtual machine with SQL
server, SQL Server Management Studio does not connect to servers any more
(E_NOINTERFACE error)
- after installing IE8 on a brand new virtual machine with Win2008 x64
(installed OS and ran full Windows Update), explorer seems to open a new
Windows every time we doubleclick on a folder instead of remaining in the
same window
- after installing IE8 on a brand new virtual machine with Win2008 x64
(installed OS and ran full Windows Update), we can't install the web server
role (IIS) any more. Digging through the logs it seems that the IIS Manager
shortcut can't be created (E_NOINTERFACE error).

Googling around we solved all these problems by running the following
command from an administrative command prompt and then rebooting:
regsvr32 actxprxy.dll

So it seems that IE8 setup messes up the registration entries from
actxprxy.dll!
This is a very serious flaw that affects a lot of people. Does anybody know
if Microsoft intends to fix this?

regards,
Stefan.

The behavior you describe and which you resolved by re-registering
actxprxy.dll is usually caused by real-time "system protections" running in
the background when IE8 is installed (e.g., anti-virus; anti-spyware;
third-party firewalls).
