It is a very good alternative to Sumatra, and evidently its greatest advantage over this are the PDF annotations. Some functions that I use a lot in Sumatra and that are NOT in Okular are:
Open multiple files in tabs, in a single window. Okular works Office style, it will open one window per file, which is not practical.
File history, and possibility to reopen them ALL automatically when starting the program.
In the Windows version, Okular occupies more than 400 Mb, while Sumatra less than 20 Mb.
Finally, a very commented problem is the lack of a "standard" installer in Windows. I had the same problem, and after abandoning all this and trying MuPDF (quite limited) I gave it a last chance, and it turns out that IF THERE IS an installer that is very hidden...the link is below.
There you will find the typical *exe, and also a 7z compressed that will make the portable version (the executable is in the bin folder). If you navigate within that web, you will also find the "Nightly" versions of Okular, and also other applications of the KDE community

Historial de archivos, y posibilidad de reabrirlos TODOS automaticamente al iniciar el programa.

Alli encontraran el típico *exe, y tambien un comprimido 7z que hará las veces de versión portable (el ejecutable esta en la carpeta bin). Si navegan dentro esa web, también encontrarán las versiones "Nightly" de Okular, y tambien otras aplicaciones de la comunidad KDE.

This is the only PDF (PDF only!) reader that satisfies me fully in all 3 dimensions: open source, functionality and speed. All the other readers that I tried have a shortfall in at least one of the 3 - Adobe Reader, Foxit Reader, Sumatra, DPF.js, STDU, Icecream ebook reader. I won't describe it in full, you'd better try it and see for yourself. I'll just mention my favourite functional features - cursor pointing to the active chapter in the contents tab, Trim margins option, filter field for all tabs - Contents, Thumbnails, Reviews, Bookmarks and a convenient hand tool switch (it's called Browse). But keep in mind - it's good only for PDFs and only for reading. It's bad for reading epubs for example and can't edit files. Also its installation on Windows is hidden somewhy, but all you need to do is install KDE via KDE on Windows from Sourceforge. This installer incapsulates the programs including Okular.

Can not find Ocular installation for Windows. I don't think it exists.
TerrifiedTyphlosion
It exists. I have it installed on three Windows machines right now. Like you, though, I had trouble finding out how to install it on Windows. I think there are multiple ways of getting Okular onto Windows. The method I used is using some package manager called "Chocolatey". It requires using the command line, but if you follow the instructions in the links below, you should be fine.
@TerrifiedTyphlosion is correct to state there is 'an' installer.
Not a 'Windows' installer, tho.
The CMD command line may still be a part of Windows. But DOS or not, the command line is not what most end-users think or generally accept as being a normal Microsoft-style window, not in the 21st century anyway. Or the last part of the 19th, either.
Not a criticism - an installer is there! Just to let GUI noobs like me know that it's ..complicated. More complicated than a download and double click.

Can be installed from Windows Store. But it doesn't work good at the moment on Windows. App always opens only half on the screen. It won't remember its position and window size. Tabbed functionality doesn't work on Windows either. Every new file opens in a new window. Open new files in a new tabs checkbox does nothing. https://www.microsoft.com/store/productId/9N41MSQ1WNM8

I'm in the same boat. I like the look of it but I'm not opening my DNS to microsoft.com so I won't be installing it from the store. Does anyone have an exe installer / zip etc?
Since I'm a KDE user, I was happy to see Okular available for Windows.
However, it quickly let me down, at least with epub files. Opening a 2M epub file that opens instantly in SumatraPDF consistently takes 7 seconds in Okular. The font is incredibly tiny and unreadable. If I zoom in enough to make the font large enough to read, it fails to reflow the text (which is the whole point of reading epubs instead of pdfs) and display the entire line. After digging through settings, I did find a backend configuration where I could select a default epub font. That works, but requires you to reload the document. I tried a number of stock fonts, but they were all rendered without antialiasing, making them jagged and hard on the eyes. All of this was too much effort without real payoff.
I did test a couple of pdfs and found it handled them just fine. But since my goal was finding a cross-platform reader that reads all my most used document formats, I'll have to keep looking.

Remembers last time you left it. Runs superfast. Cross-platform.
Thumbnail view is a blessing. Just note when you re-open the last document, the thumbnail column will be unsynced until you go to the next/previous page.
From Debian 10 using i3wm.

It supports not just pdf but also many digital document formats and not as complex as Calibre.
