Windows 10: Who issues the App Explorer updates?

I'm working on a new PC for a relative & got a message saying App Explorer was being updated. What I'm upset about is the fine print saying it was also changing my web browser search page-or something like that. (I should know better but I failed to write down the exact message.) This is a Toshiba & I know they have several of their own apps-is this one of them or is it Microsoft?

I'm paranoid. It's a shame but experience has taught me that you should always be paranoid when working with Windows. The problem is that most of the people whose computers I work on aren't paranoid-that's why it upsets me so much when I see a supposedly legitimate company trying underhanded tricks to stick it to their customers. I get even more upset when the companies don't identify themselves-and this popup had nothing except the message.

I rather suspect this was Microsoft but don't want to accuse them unjustly. So does anybody know where the App Explorer Update came from? Thanks.

Very slow to load Downloads folder in Windows 10

I received help from MS engineer Brian. He narrowed down the issue to opening dialog from one web page. It seems that native apps do not experience the issue.

Anyone who has the issue might verify if this problem happens in file explorer or when using open dialog from web pages.

 

Photos app hogging resources in background

For those who do not use OneDrive, and still have this issue (as I did) - you can remove OneDrive from File Explorer and that seems to - for me, at least - resolve the issue of the Photos app hogging CPU resources. The tutorial for how to remove OneDrive
from File Exporer can be found
here. Do note that it involves editing a registry key.
