I am throwing this out on this forum because I have tried everything with no avail here is the situation. I am working on a computer for a client who has windows 7 64 bit. The problem is that whenever you try to install or uninstall a program it hangs or is really really slow.
I notice most of the time an installation might get to a certain point and just churn and churn. In other cases when trying to uninstall some antivirus program the iuninstaller started but just hung for 3 hours or more till I finally had to shut down the computer by holding the power button in for 3 seconds because the shutdown routine was hanging as well.
When I got booted back into windows I noticed that the program I was attempting to uninstall at least looked uninstalled from the program and feature list but certainly it was plain to see that it wasn't totally eradicated after a quick look at the windows registry in which case I got rid of the left overs of keys that I was absolutely sure was part of that given program.
Anyway having said all this I have tried everything in the book to try to troubleshoot why this install/uninstall was so slow if indeed it would actually finish and why turning off the computer many times would hang.
I did everything from booting into safe mode to booting into normal mode and using msconfig to selective disable certain services.
In fact I attempted to at the start disable all services that were disabled in safe mode with networking since it seemed like everytime I restarted or shut off my computer from this mode it was successful it was only in normal mode where it failed.
Once I didn't get to far in normal mode even with all the services disabled I than went ahead and disabled all the hardware I felt I could via device manager even to the point of diabling the graphic adaptor hence getting a lower screen resolution.
Anyway having said all this it appeared that when I had the display adaptor disabled as well as the microsoft framework 4.0 services I could usually shutdown and restart successfully in this normal selective mode but still ran into the same issue with installation hangs as I tested trying to reinstall an antivirus program and saw it just churning and churning on the screen that said please wait.
I also observed in some cases that if I restarted the computer and than immediately shut it back down many times it would shut down successfully but when I did a few things in the computer first and than tried to shut down it hung with the words shutting down or sometimes it hung with the words preparing to update your configuration do not turn off your computer.
I know it wasn't doing anything because I left it in this state for about 5 hours or more this morning and when glancing at it again I saw the words shutting down yet still hadn't shut down.
It seems like it's hard for me to install msi extensions for sure. I am wondering if for some reason something is flakey with the windows installer in this windows 7 64 bit.
I also wanted to check for viruses since my client thought they may have had a virus so I tried to install malwarebytes which did install successfully and I did a full system scan with this after updating its database and it found about 17 pieces of adware but nothing more than this so I assume that if their was a virus in this system it was taken care of.
The client had bitdefender and avg free installed in their computer and I eventually got these two programs uninstalled thinking this might be the reason for the hangs but in vain it did not work.
What was consistant is that anytime I was in safe mode I seemed to be able to always shutdown or restart successfully without holding the power button down for 3 seconds. Of course I couldn't test the ability to install or uninstall software since this is not possible in safe mode even in safe mode with networking.
But in normal mode even with all the services and hardware turned off that I felt I could it was finiky in the way it behaved in regards to shutting down or restarting correctly though one consistant thing seemed to be that when all this stuff was disabled and I immediately shut down windows without doing anything after restarting the computer it seemed to shut down correctly every time it is just if I were to open a few things, test a ;few things and than shut down this is when things became problematic in regards to successfully shutting down windows though as I mentioned all that I have done did not seem to phase the issue I am running into in regards to installation or uninstallation of programs.
