how to completely uninstall a software

@sam9 that's easy to find which version your programs are. Any program in your Program Files folder is 64 bit. Any program in your Program Files (x86) is 32 bit. Hope that helps you.

Thanks, I knew this but had some doubt whether this is 100% right that 32 bit will be in Program Files (x86)

And my System hanged both time when I was in my mail.

Yes this is the way Microsoft has done this for years. Their are some app's that will install themselves into BOTH folders, because they can operate at both 32 and 64 bit levels. For a example Nvidia installs itself into both folders. Reason being some apps run only under 32 bit mode, while other app's only run under 64 bit mode, so a program like Nvidia has to be able to handle BOTH kinds.

I will wait for few more days, if the system hangs again then I will try any thing else. In the meantime, some one has said that many times PC hangs when windows updates are getting installed. As in Windows 10 updates happens at back hand so how can I come to know that updates are installing.

You can note the time any problems arise and then look back to see when Windows Update was active. Goto 'settings' and then 'Update &Security' You should see for example, Your device is up to date. Last checked: Today, ‏‎14:33. You could also look in event viewer to see exactly when updates were being installed. Most days should only see Defender updates being actioned anyway.

On my older laptop I definitely do notice when Windows Update is running (a bit slow, lots of HDD activity) but on my Dell laptop with an SSD Windows Update running never becomes apparent.
