How to delete multiple lines with different text in between using RegEx in Notepad++?

Question

What I need to do is to delete everything that ends with desktop.ini and begins with Library with varying text in between.

In my list, it looks like this:

Library\aaaa\desktop.ini
Library\bbbb\1111\desktop.ini
Library\bbbb\line-I-dont-want-to-delete
Library\cccc\222\CCCC\desktop.ini
Library\dddd\3333\D\desktop.ini

After using the Replace feature, all that should be left is:

Library\bbbb\line-I dont-want-to-delete.

I'm really terrible with RegEx, but what I need is something like this:

^Library\$[(A-Z)?]\desktop.ini

Apologies if that's all I have, but thanks in advance for helping me with this!

A shortest possible code can be ^lib.*ini\n so that you not forget it soon next time ...... — Haji Rahmatullah

You can use

Find What:    ^Library\\(?:.*\\)?desktop\.ini$\R?
Replace With: <empty>

Details:

^ - start of string
Library\\ - Library\ string
(?:.*\\)? - an optional non-capturing group matching zero or more chars other than line break chars as many as possible and then a \ char
desktop\.ini - a desktop.ini string
$ - end of line
\R? - an optional line break char (sequence).

See the demo below:
