Microsoft Windows has supported a pluggable image codec model since Windows Vista. It is entirely within Adobe's purview to create a PSD codec for Windows, but they have for whatever reason chosen not to do so. For a while they offered a DNG codec in preview through Adobe Labs, but even that has been left to languish is no longer officially available.
There are a couple of legitimate third party suppliers for Windows image codecs. I believe they may have free trials available. Check these out:

You can, of course, choose to use layered TIFF files instead of PSD for your Photoshop work. This is what I do (choosing the option to maximize compatibility). Windows can thumbnail TIFF files natively, and this avoids both the cost and potential instability of a third-party decoder.
Hope this helps.

Windows 10 really should do this natively but Microsoft doesnt care about quality. The so called "Creators Update" should have included this as a feature. Its what real creators need, not a 3d paint UWP toy.
This was the codec I bought. It was a while ago but the page has a lot of detail on specifics and at the time it was the only way to view thumbnails in explorer because MS hadn't updated the codec pack. Lots of forum talk about that, everything pointed to that codec as the only option and I agree unless i wanted to use a program to browse the images. I'll let you dig for specifics cuz it was a while ago.
If you aren't viewing raw photos, than the free version of http://www.fastpictureviewer.com/ is very good. It is tweaked for performance and allows you to sort/keep/star photos very quickly. You can figure how much ram it uses per image as well.
MysticThumbs (+ ghostscript to enable AI and PDF files) - $25
FastPictureViewer Codec Pack - $15
I prefer MysticThumbs. Indy developer, constantly updated, has more options (including transparency, which might help you), and more supported formats. I get the feeling that FastPictureViewer only extracts embedded thumbs for specific formats too, while MysticThumbs can actually load the image format.
There is also a free Koshigaya Thumbnails which would give you PSD, but not AI/PDF, but I can't seem to find a working link and it only worked with 32-bit Windows.
...and Koshigaya Thumbnail Support if you need more formats. 32-bit only apparently.
Or two 64-bit alternatives, that cost money:
http://mysticcoder.net/mysticthumbs.html (if you need graphics formats like Maya IFF) http://www.fastpictureviewer.com/codecs/ (if you need camera RAW formats)
I agree with you completely. I don't use Irfanview but a different codec plugin for Windows 7 that does the same thing. Thumbnails while browsing in explorer show just like a jpeg. I spend most of my time in Lightroom anyway.
Edit: I use Windows 7 64bit and shoot with a Canon 7D and this does the trick (only $15)... http://www.fastpictureviewer.com/codecs/
Also replied with link to Qro and JackAttackNZ so they got orangered. Sorry for the multiple link postings!

You should not rely on Raid and should always keep backups.
Windows Picture Viewer is not color managed, which means photos look nothing like what I had in mind during editing. I found a color managed viewer called Fast Picture Viewer a while ago, and I think it's really good. Try it out, maybe?
I'm not so sure I've found the perfect viewer myself. ACDsee is pretty good for non wide gamut monitors because the quickview is nice but useless for wide gamut monitors. Bridge is still great but its not good for just viewing images out of the file explorer fast like Irfan or ACDsee quickview.
http://www.fastpictureviewer.com/ is one of the best out there. For some higher level production work Tweak softwares RV is fantastic. Again though I've not really found one I absolutely love the best yet. Irfanview was that for a long time but its ui is dated and lacks some professional stuff that would make it very useful. This is where RV is a great tool.
Not free, but you could try this. It has a two-week trial.

I bought Fast Picture Viewer before I had lightroom, but I still use it to cull away before importing to lightroom if I've been using burst shooting, etc.
It's GPU accelerated for viewing, very fast to load, zoom in and pan around an image.
For your usage case, you can either delete images marked with x key or move then to a "scrap" folder using the file plug-in bundled with the program.
Have you installed anything else on your machine? I'm asking because some apps will install "codecs" that will replace the default Windows ones and might not work when called from XAML.
I've had similar issues with FastPictureViewer Codec Pack in the past.
Fast Picture Viewer might be what you want if you have windows.
It doesn't do any kind of editing, like lightroom, but you don't have to wait for photos to be imported, and it is super fast.
I bought FastPictureViewer Pro after trialing it for a bit (hooray for fully-functional trials!).
As it's name might make you think, it's fast, and fairly simple. My favorite feature is the "keep" feature - you set a folder on your computer as the "keep" folder, and as you go through your pictures (I go through them directly off my SD card), you press 'k' to copy the picture to the keep folder. Combined with the "left click to zoom to 100%", it makes going through a day's worth of shots a fairly quick task.
I use FastPictureViewer Professional on my laptop, and I love it.
FPV has a "keep" function where you specify a folder to copy to and your camera card, and mark pictures to keep as you go through all of the pictures on your card. I find that this makes it really easy to go through several hundred pictures fairly quickly, copying the good pictures to my computer for more detailed review later.
Are you looking to just view your images, or manipulate them as well?
If you're in search of a CODEC for your machine in order to be able to view RAW files within Windows Explorer (I'll assume you're on a Windows machine. If not, then I apologize) then I would suggest "Fast Picture Viewer." Go to this link and download for either your 32 or 64-bit platform. The software comes bundled with a bunch of other "stuff," but allows you to select what you want specifically installed on your machine during the initial installation process. I recommend selecting the option to install the necessary CODEC for RAW files only - this de-selects the bloat.
As far as image manipulation is concerned; well, we can run the gamut on that one. If that is what you're looking for, set out some specifics like budget and what you're looking to get out of such software.
Good luck; have fun :)
