Why does Thunderbird update require a Windows 10 restart?

For some reason my Desktop Windows 10 system now requires a Windows restart not just a Thunderbird restart when I update Thunderbird. I don't seem to have this problem on my new laptop.

Chosen solution

That is I deleted the Mozilla Thunderbird folder in Files(x86) and reinstalled Thunderbird. I did this from my standard user account.

Did you shut down Thunderbird first? I'd expect you get a UAC prompt for both of these actions. Did you?

My standard user account profiles.ini is not relative but points to my administrative account profiles.ini.

I don't understand what that means, and what this is good for. There is a profiles.ini file for each Windows user account where Thunderbird has been started at least once.

Restarts are required when files that are in use need to be updated. In these cases windows institutes a restart to force the files out of use so they can be updated.

Matt: Thanks for the reply but I doubt that is the problem. Thunderbird would update without restarting Windows until a few months ago. I don't see this problem on my laptop. I will close Thunderbird the next time I update my desktop and hope you are right and a Windows restart does not happen.

You'd need to be a little more specific about what you did.

christ1: I followed the instructions in the link you referred me to. That is I deleted the Mozilla Thunderbird folder in Files(x86) and reinstalled Thunderbird. I did this from my standard user account. My standard user account profiles.ini is not relative but points to my administrative account profiles.ini. This has worked for years.

Christ1: I did delete the directories suggested and it seems to have worked. It escaped me that when the directories were missing Thunderbird thinks it is a completely new installation and of course would need to restart Windows. I was able to update to the latest version without a Windows restart so the problem seems to be solved.

Just a not. If you look at a profiles.ini file you will see a line such as: IsRelative=1 Path=Profiles/nmwpbuc6.default Path shows the location of the desired profile. If IsRelative is changed to 0 then Thunderbird expects a full path to the desired profile. I have my preferred profile in my administrative account Thunderbird directory which I leave as relative. I change IsRelative to 0 in my standard user account and put the complete path to the profile in my administrative account so Thunderbird is the same whether I am in either account. I do the same with my Firefox ini profiles.

Ok It turn out the problem is not solved. I did delete the x86 Thunderbird folders and reasonably had to reboot/restart Windows 10. The next time I was alerted to a update for Thunderbird it updated as expected without requiring a Windows 10 reboot. I just got a alert that there was a new version of Thunderbird and proceeded to download the new version as directed. Low and behold I had to reboot/restart Windows this time. It sure seems like there is something in the registry or the profile that causes Thunderbird to think the update needs a reboot.

I have been using Thunderbird for decades so the profile file has been updated through I don't know how many revisions and versions of Thunderbird.

I have included a screenshot of the update section of Thunderbird Options. I would note that the Automatically install updates is selected but that does not seem to be happening.
