If someone is able to download an exe and install a program, they're able to click on a link to the store and install the program...

Besides, that article is outdated. As far as I can tell, every complaint has been fixed.

Everone knows how to use a browser to some extent.

Windows Store adds one extra step(either a complicated link or search in store)

Yes it is a trivial step for most users but those needing the help most will struggle.

https://apps.microsoft.com/store/detail/quick-assist is not exactly shining with positive reviews.

That said I will evaluate QuickAssist and see if it actually meets my needs.

That link gives me a wonderfully helpful "Invalid product ID" message.

Not even styled, it's just a HTTP 400 page with some cookies and that message. No HTML.

Yay Microsoft...

Indeed!

The actual link is https://apps.microsoft.com/store/detail/quick-assist/9P7BP5V...

That is about as easy for grandma as 0118 999 881 99 9119 7253 phone number..
