Microsft needs to jump on what quick? The fact that *your* computer is
messed up but millions of others are not - so it is obviously their fault?
Yeah - I bet they will get right on that. ;-P

10/100/1000/10000 problems does not an incident make when you are talking
1000000/10000000 systems in total. Something is wrong with *your* system -
something corrupted it/messed it up bad. Could be a whole bunch of things -
even back to the original installation (or most likely imaging) from the
manufacturer. Given that not every Microsoft Windows user (not even 50%
from what I have seen, I'd venture to say less than 2%, probably less than
1% - but that is pure speculation by observation) is having the issue - it's
more likely an issue with the specific systems than an issue Microsoft
caused and should fix. (They have caused and had to fix problems in the
past.)

So - let's go through your problem *if* you are wanting to fix it.

You should get the edition and version information...

Start button --> RUN
(no "RUN"? Press the "Windows Key" + R on your keyboard)
--> type in:
winver
--> Click OK.

The picture at the top of the window that opens will give you the general
(Operating System name and edition) while the line starting with the word
"version" will give you the rest of the story. Post _both_ in response
to this message verbatim. No paraphrasing - instead - ensure
character-for-character copying. That's the edition (in the top picture)
and the exact version number in detail (the 'version' line.)

Is your Operating System 32-bit or 64-bit?

What version of Internet Explorer are you currently using? Easy to find
out. Open Internet Explorer and while that is in-focus, press and hold
the "ALT" key on your keyboard. With the "ALT" key still pressed, press
(just once, no holding) the "H" key. Now, with the "ALT" key still
pressed, press (just once, no holding) the "A" key. That will bring up
the "About Internet Explorer" window. It will give you the exact version
you are using - repeat what you see there in response to this message.

What AntiVirus application are you using? (Name and exact version, please.)
- Was any flavor of "Norton" products ever installed?
- Was any flavor of "McAfee" products ever installed?

Do you have a third party firewall - or are you using the built-in Windows
XP firewall?

Do you ever run any antimalware applications? If so - which ones and when
did you scan with them last (full scan, not quick)?

Since I do not know your Operating System (OS) yet...

Reboot so you start with a fresh machine. For everything here you will
need to logon as an user with administrative (installation) priviledges.

Download/install the "Windows Installer CleanUp Utility":
http://support.microsoft.com/kb/290301

After installing, do the following:

Start button --> RUN
(no "RUN"? Press the "Windows Key" + R on your keyboard)
--> type in:
"%ProgramFiles%\Windows Installer Clean Up\msizap.exe" g!
--> Click OK.
(The quotation marks and percentage signs and spacing should be exact.)

It will flash by *quick*, don't expect much out of this step to get
excited about. But the cleaner your machine is to start with, the
better your luck will be later (not really luck - more like preparedness,
but that's not as fun to think about, eh?)

Yeah - you will get tired of rebooting - but let's soldier on and reboot
again and logon as an user with administrative priviledges.

This time (and this is one of the more time-consuming steps) you will be
running (one at a time with a reboot in-between) three different
anti-spyware/anti-malware applications to ensure you come up clean.

Download, install, run, update and perform a full scan with the following
(freeware version):

SuperAntiSpyware
http://www.superantispyware.com/

Reboot and logon as administrative user.

Download, install, run, update and perform a full scan with the following
(freeware version):

MalwareBytes
http://www.malwarebytes.com/

Reboot and logon as administrative user.

Download and run the MSRT manually:
http://www.microsoft.com/security/malwareremove/default.mspx

You may find nothing, you may find only cookies, you may think it is a
waste of time - but if you do all this and report back here with what you
do/don't find as you are doing all of it - you are adding more pieces to
the puzzle and the entire picture just may become clearer and your
problem resolved.

Reboot and logon as administrative user.

At this point - if the machine was mine - I would follow these directions:
http://social.answers.microsoft.com/Forums/en-US/vistawu/thread/ea20ba99-017e-4ae0-975b-1ef8b771dff8

In other words... Use the .NET Cleanup Tool (Method 2), reboot and install
the .NET Updates in this order:

- .Net Framework 3.5
(http://www.microsoft.com/downloads/details.aspx?familyid=333325FD-AE52-4E35-B531-508D977D32A6)
- .Net Framework 1.1
(http://www.microsoft.com/downloads/details.aspx?familyid=262D25E3-F589-4842-8157-034D1E7CF3A3&)
- .Net Framework 1.1 SP1
(http://www.microsoft.com/downloads/details.aspx?familyid=A8F5654F-088E-40B2-BBDB-A83353618B38&)

Should be good to go.

Needs repeating in full?
When installing updates using Windows update or Microsoft Update you may
receive Error 0x643 or 0x80070643 (23 Oct-09)
http://support.microsoft.com/kb/976982

=====================

Step #1 => Before doing anything else, write down what .NET Framework
versions are currently installed:

How to determine which versions of the .NET Framework are installed and
whether service packs have been applied
http://support.microsoft.com/kb/318785

Step #2 => Now see Resolution Method 2 in this related KB article...

When you try to install an update for the .NET Framework 1.0, 1.1, 2.0, 3.0,
or 3.5, you may receive Windows Update error code "0x643" or Windows
Installer error code "1603" (ignore the title, if need be)
http://support.microsoft.com/kb/923100

After running the .NET Framework Cleanup Tool, reinstall all .NET Framework
versions (but only the ones you wrote down in #1 above) manually using the
download links on the page then run Windows Update manually to install
security updates for same.

NB: If you remove .NET Framework 3.5 (SP1) using the tool, reinstalling .NET
Framework 3.5 will also install .Net Framework 2.0 SP2 and 3.0 SP2; then
Windows Update will offer .NET Framework 3.5 SP1.

IMPORTANT! => If you remove .NET Framework 3.5 (SP1), reinstall your .NET
Framework versions in the following order:

1. .Net Framework 3.5, then...
2. .Net Framework 1.1, then...
3. .Net Framework 1.1 SP1

NB: KB923100 references this page:
http://blogs.msdn.com/astebner/archive/2006/05/30/611355.aspx. Please read
ALL of it as well as the related page
http://blogs.msdn.com/astebner/pages/8904493.aspx before using the .NET
Framework Cleanup Tool.

Come back - let everyone know if this fixed the problem you were having with
your system.

I spent forever figuring this out. There is some hijackware blocking windows
update.

The standalone Window Update Agent (Wusa.exe) can be used to apply security
and windows updates one at a time (.msu standalone versions of the updates
which can be found by searching microsoft knowledge base). When you get
completely up to date, the hijackware gets blocked. I applied the last 12
updates one after another and the fix was in one of those. It is unfortunate
that I cannot pin down the exact update.

This approach has to faster than an in place upgrade.

Here is a simple solution that has worked for me. I downloaded and installed
a 30 day trial version of ErrorFix (registry cleaner). It recognized the MS
updates, downloaded and installed them. When I checked the update history for
vista the updates were listed there. However, windows updater still won't
work and gives the same error. But at this point I have had enough and will
purchase the registered version of this program and use it to obtain MS
updates. I have been checking the internet about this problem and it seems to
go back for quite a few months. But where is MS in helping to solve this
problem. Maybe my next purchase will be an Apple computer....

If you ever think your Registry needs to be cleaned, repaired, boosted,
tuned-up, or optimized (it doesn't), read
http://aumha.net/viewtopic.php?t=28099 and draw your own conclusions.
