Windows Not Updating Correctly

80010108 RPC_E_DISCONNECTED
The object invoked has disconnected from its clients.

Open Windows Update on the Start Menu ( click the Start orb > All Programs > WIndows Update ), the click the Check for updates link in the left frame.

When the check is finished copy and paste the last 50 to 75 lines of the WindowsUpdate.log (WU.log for short) into your reply, please - How to read the Windowsupdate.log file

FWIW, the most recent entries are at the bottom of the log. You can go back up in the log and look for entries that contain FATAL for a clue as to what's occurring.

Will wait for you to post the requested part of the WU.log before recommending any remedial steps. That specific return code is a tad unusual and I have never seen it before.

I attempted to check for updates but it never completed. I had it running for almost 2 hours and it never completed the update check. In the bottom right-hand corner, I have the Windows Update icon there and, when I hover over it with my mouse, it shows Windows Update is 8% complete. So it IS downloading the updates but it's VERY slow. It's been at least 8 hours and it's only gone up to 8%, so there's obviously an issue. I can show you what I have in my WU.log as it is right now if you'd like.

Edited to Add: After starting up my computer this morning, I found that the Windows Update is now up to 40% complete. I also tried to update MSE and I got a message stating that MSE couldn't update the definitions due to an internet or connectivity issue. Which is strange because obviously I can go online and I have no other network issues.

MSE should install it's definitions first, before any updates install. It's difficult to assess what the issue is without first seeing the WindowsUpdate.log. However, it's quite obvious that something ain't right.


1. Is a 3rd party firewall being used ?
2. Was another antivirus/security suite installed before MSE was ?


You can either wait for this month's round of massive updates to install or you can open the Windows Update Troubleshooter ( it's under System and Security ) and see if it can speed things up some.

To be perfectly honest here, I've not seen the specific return code, 80010108, before in 10 years of helping folks out with Windows Update issues. I'm leaning towards either a malware/network connectivity issue, or a combination of known troublesome updates ( .NET Frameworks or Visual C++ ) as being the cause.

Can you manually download, save, and then install the latest definitions for MSE ?

Either click this link to obtain them - Microsoft Security Essentials 64-bit, June 24, 2011 or, go to the Microsoft Malware Protection Center and click the 64-bit link next to Microsoft Security Essentials, 64-bit.

Save mpam-fex64.exe, do not run it with the browser open.

When the download completes close the browser and all other open program or applications.
Right click mpam-fex64.exe and choose 'Run as administrator', then agree to the UAC prompt to install the defs.

If the system is still installing updates then suggest you restart it to Safe Mode for now - How to Start Windows 7 in Safe Mode
All of the previously downloaded updates will resume their installation after you've done a system scan from within Safe Mode and the system is restarted to normal Windows mode.

Please let us know about your results from using the Windows Update Troubleshooter, in updating MSE, and the results of the MSE scan from Safe Mode, along with the answer to the 2 questions.

Approximately 2 days ago Windows tried to install 12 updates. It got stuck on update number 2 for at least 2.5 - 3 hours. I eventually had to do a hard shutdown so I could move on to my linux distros and get some work done. I'm reluctant to boot windows because I fear I'll be forced to do the same. Is there a remedy for this? Thank you. BTW this is Win 7.

gdawg65,

To avoid confusion please start your own thread and attach the WindowsUpdate.log to it - How to read the Windowsupdate.log file

Thanks !

1. I just use the Windows 7 firewall.
2. McAfee was installed on this computer during setup by a coworker, but this was over a year ago. Long before MSE was on here and I hadn't had any problems with Windows updates or MSE updating until about a week ago.

I ran the troubleshooter, it took a while for it to finish but the updates are still taking just as long. I am able to manually download and install the MSE update, so I ran a full scan and it came up empty.

Again I attempted to d/l the Windows updates and as I type this, the 3 updates that I have checked to install are currently installing correctly but I have to restart to make sure they install completely.

After restart I checked the update history and 3 of 4 updated successfully while one failed. The one that failed had that same 80010108 error code.

Did you do the scan from within Safe Mode or in normal Windows mode while the updates were installing ?

The 80010108 return code in this situation apparently means that updates are installing that need to be installed by themselves, therefore the client, your computer, is disconnecting from the update servers or a COM object that is being updated is disconnecting from it's "server", which in this case, is actually it's service, so that it can update files that are in use

If you want to find out which updates are still installing then either attach the entire WindowsUpdate.log (WU.log) or post the last 50 - 75 lines of the WU.log - How to read the Windowsupdate.log file
