Autoinstallation of installable Google Chrome on Windows 11

Hi, folks!

My respect to all developers, who make our lives easier, contributing their personal time for making our favourite apps portable.

Could anyone tell me, why does Google Chrome reinstalls itself though I kinda don't have and want Google Chrome installed. It while by while again appears on my Windows 11, sometimes even the icon logo comes on to my desktop. I've been deleting it from the installeds for already a year and keeps on appearing among my installed applications. Is because something's wrong in my Google Chrome portable that it can iterate some installation processes after I update it in Portable Apps?

Thanks to all who can help me!
