On my machine (Windows 7, 64 Bit) the TrustedInstaller.EXE is permanently active. The amount of used CPU changes permanently. 2 seconds 0 % then up to 50% (I have a dual core) for a second then down to 0.

Rebooting the machine did not help. Also a complete Virus scan was negative.

I have monitored the process with the Process Explorer tool. I can see that the process always access the same Registry key when it gets active. The key is

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\PackageDetect\Microsoft-Windows-IIS-WebServer-AddOn-2-Package~31bf3856ad364e35~amd64~~0.0.0.

Hi Robear,

in the meantime I have found the process that was responsible for the trustedinstaller activities. It was the xenservice.exe that was installed together with the Citrix XenCenter on my machine. I have killed this process and suddenly the trustedinstaller.exe stopped its activities. So the problem is solved now because the XenCenter can work without this process and I will remove it from the auto

Thanks for your help.

Martin

    Two MS MVP players have encouraged me to let it try to update for at least 24 hours nonstop.  I set power options to never sleep but screen dim okay.  Started trying for updates at 4 pm yesterday and this morning at 6am I see 214 of 241 updates downloaded and installed!!  :-)

    However I got my first ever "Low Memory" message when I took a look.  Not much I can do about that except let it run for another 12 hours I guess.

    Don't give up - for whatever reason Update is just taking an extremely long time to do its job.

    Maybe due to so many people upgrading to Win 10??  I have no clue.  Good luck with your wife's.

    Well I brought this laptop back to factory. There was so many failed updates that this thing just seemed to stall out for 12 hrs or more.

    First few updates 40 or so went real well. Then 100% CPU usage with svhost this time. I just let it sit and about 6 hours later it finally said I had 213 updates.

    But svhost is still at 100% lol. It's downloading now and at this rate it will be tomorrow night before it is finished.

    I think you right that the issue is MS servers. I know it's not my cable ISP.

    Not good news for me!  So I am having a similar experience with updates.  Takes hours for it to find and list them.  At first I had it set to Auto. download AND install updates.  Big mistake!  Installing 222 updates at one time caused a LOW MEMORY message to appear.  I did my best to free up more memory and also increased the Virtual Memory settings to 5902.  No help on that try,

    On the next try it came up with 241 updates!  Since it was still in auto. mode it tried to install all of them at one sitting so to speak.  It HUNG on #214 for 3 hours before I killed it.   I had not changed updates to download only and let me pick which to install.  This time the laptop ran out of memory at #237 of 241~~not good.  Once again I had to kill it and of course it REVERTED changes.

    Each time I killed it would cause changes to revert.  After that it only found 107 updates.  I had changed it to d/l and advise me.  This amount did install BUT when it shutdown it only partially configured and said it failed configuring but it rebooted itself and tried to install on startup.  On startup this time it went to 6% and failed to configure once again.

    Checking installed history I see many updates did install - mostly .NET 3.5.1 security updates.  This morning I have it looking for updates now so it will be a while.

    My plan is to clean install Win 7 Pro when it arrives next week.  Your news is not good for me.  If a clean install doesn't work out I am not sure of my next steps.

    It is definitely on MS!  All other downloads including programs, PDFs, etc. download and install without issue.  I don't know why MS has problems but I have suspicions.  It could be that so many globally are still updating to W10 and so we get low priority; it could be that MS is trying to discourage reusing older equipment so you will buy new with W10 already installed.  

    I have been a PC tech for many years and have never seen such misery bringing a PC up to date.

    Good luck with your download and install.

    To bad these posts are not time stamped LOL. 24 hrs later it finally got 205 updates installed before the low memory issue popped up. Took 3 hours to tell me I have 30 more updates and I know we are not finished yet.

    When I get this finished with no KB updates for W 10 (I'll remove them) I am going to turn off updates and make a disk image for this laptop.

    I'm also going to put Microsoft into my hosts file and stop it altogether from connecting.

    Next job it to clean out my PC that I use for my photography so it doesn't install W10 on it.

    I have lost all trust now with MS over this.

    I think your right and MS is throttling their download servers.
