I don't have the answer but curious, was the Windows Sidebar open when trying
to install/search for updates?

[Max Nodir]

Hi there! No, the sidebar was closed and I don't have any Norton stuff
installed. I don't get it, what is the problem? Plus, my antivirus is
Kaspersky and it is off too, but still I can't keep my system up-2-date!

PLEASE, SOMEBODY, ANYBODY HELP!!! PLEASE, SOMEBODY, ANYBODY HELP!!! PLEASE,
SOMEBODY, ANYBODY HELP!!! PLEASE, SOMEBODY, ANYBODY HELP!!!

Thank You before hand for your support and help!

The Windows Update icon is on my taskbar all the time, saying as usual "New
updates are available" and when I try to install these new updates, still
error 800B0100 comes up. Any ideas, hopefully, solutions?

I got exactly the same error message when trying to install an "important"
update. I think the problem is that the updater can't download the update
(reason unknown). However, I resolved the issue by downloading the update
directly from MS update website.

SOLVED IT!

I have been trying to solve this 800B0100 error for months, and last night
solved it!

For me this was the solution:
1. Click Start, on "Start Search", type "cmd" (without quotations mark) and
right click the command prompt icon select Run as Administrator.
2. In command prompt, type the following command and Enter: regsvr32
wintrust.dll

If this doesn't work for you try the following:
1. Disable any Firewall, Antivirus, download accelerator software.

Firewalls and Antivirus programs are 3rd Party (non-Microsoft) Programs, and
although they are mostly effective in protecting your computer from Viruses
and Computer hackers, they do fail to take into consideration program
installations. The nature of these programs is that they scan everything on
the computer, making sure to try and stop any virus-like activity.

When you visit Windows Update and download, and most importantly install any
of the updates, the update installation is always battled by the Antivirus
and Firewall until the Antivirus clears the program of being a virus. In most
cases, this is harmless and the Update installation goes through
successfully. Occasionally, the Installation gets corrupted, and a process
during the install is stopped, or interfered with by the Antivirus product.

For this reason, we suggest that you disable any Antivirus or Firewall
software while trying to install updates from Windows Update.

2. Verify the Language Settings

2.1. Start Internet Explorer.

2.2. Click "Tools", and then click "Internet Options".

2.3. Click the "General" tab, and then click "Languages".

2.4. In the "Language" list, make sure that the operating system language
version is included. If the operating system language version is not on the
list, click "Add", click the language in the "Language" list, click "OK",
click "OK", and then click "OK" again.

3. Reset Internet Zone Security

3.1. Start Internet Explorer.

3.2. Click "Tools", and then click "Internet Options".

3.3. Click the "Security" tab, and then in the" Select a Web content zone to
specify its security settings" box, click "Internet".

3.4. Click "Default Level", and then click "Apply" to set this zone to
Medium security.

3.5. Click "OK".

4. Verify that the Date and Time Are Set Correctly

4.1 In the bottom right corner of your screen, double click the time. This
will open the Date and Time Properties window.

4.2 Please check that all details are correct including the year, the Time
zone and that AM/PM is set correctly.

4.3 Click OK.

If the problem persists despite performing above troubleshooting steps, I'd
like you to perform below guidelines to download and install a new Windows
Update Agent as the current one might be corrupted.

1. Open Internet Explorer and paste on address bar
http://go.microsoft.com/fwlink/?LinkID=91237 (for 32 bit) or
http://go.microsoft.com/fwlink/?LinkID=91238 (for 64 bit)

2. A box will prompt to save a the Windows Update Agent file, save it on the
Local C: drive.

3. Click Start, on "Start Search", type "cmd" (without quotation mark),
right click the command prompt icon and Run as Administrator.

4. Type c:\WindowsUpdateAgent30-x86.exe /wuforce in the command prompt and
Enter.

5. Follow the instructions to install the Windows Update Agent.

6. Please restart the computer after the installation.

7. After restarting the PC, click on Start and choose Windows Update and it
will open a new Internet browser.

8. A box will prompt asking permission to install the Windows Update
software, click Install and proceed to download the updates.

If it still fails, type the following commands in command prompt, pressing
ENTER after each line:

net stop cryptsvc
ren %systemroot%\system32\catroot2 oldcatroot2
net start cryptsvc

Hope this works for you too!

I have had this problem since last Nov. I cannot update or even get a
list of new updates. I have followed all the setting below. If anyone
has anything else to try, please let me know.

This systems was hammered with viruses and could not get
updates. The last solution worked. That saved me the hassle of
re-installing the operating system.

After following this step, my computer's taskbar and start menu and everything stopped looking like Vista and started looking like some other, old, weird version of Windows. Everything is pale grey and boxy and very old-looking. Is there any way to fix this? It has me quite concerned.
