> 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.

Check Disk or Chkdsk runs at every boot

1. click on your start menu and open the run dialog.
2. type "cmd" and return (note: dont enter quotes)
3. Next type "fsutil dirty query e:"
4. If the return message indicates that the volume is dirty go to step 5
5. Next type "chkdsk e: /f /x"
6. After that finshes repeat step 3.
7. If it is no longer dirty then reboot and you should notice no more
ckdisk.

If this fails to fix the problem you have to move the swap file off of the drive you are working on, (yes you can put it on a USB stick) and reboot the machine and rerun the above steps. Once the machine boots properly you can then run Defrag on the drive and once it is complete move the swap file back. This would be a perfect time for a double memory static swap file.
