How about searching contents of PDF files? Win7 does it by default. Win10 won’t even do it when you set it in the folder settings. Win10 sucks.
Re: “How about searching contents of PDF files?”
Are they Adobe files?
If so, you may need an Adobe subscription.
My Windows 10 can search all kinds of web pages and files.
But when my lawyer sends me an Adobe document, I need the Adobe subscription to “find” and “select” and “copy and paste.”
Open up a PDF in chrome. Then press control + F to open up your search box.
