Why is Windows 8 File explorer so slow?

Hi
I have just upgraded from Windows 7 to Windows 8,. My hardware requirements far exceed the minimum expectations.
Dual Xeon processors 2.6GHZ, 12GB RAM, 1GB ASUS hardware accelerated GTZ550 Ti graphics card. Dual hard drive running 7200RPM. I am running Windows 8 Pro 64 bit. I performed an upgrade from windows 7
I have been using Windows 8 and I am enjoying using it. 

Issue
My big issue that I am having is the slowness of file explorer, or whenever there is an "open file" dialog window presented.
The windows latency while it builds/shows a file list is extremely slow. I didnt have this issue on windows 7. I am presuming this has something to do with the new File explorer?

Example, if I do windows key + E - file explorer appears 
If its on say the desktop, no problem. If I go to my picture library where I have a lot of sub folders with images the list slowly builds and green progress bar slowly increments.
To compound the problem, if I close the window and do the exact same thing again, the problem returns. It appears going through the pain of building the list is not cached. As you can imagine this is frustrating.


Things Ive tried:
Reducing the file list columns = no better, stil slow
Disabling Windows Defender = no better, still slow
Closing all open apps = no better, still slow

Any help or assistance on this matter would be greatly appreciated

I think I may have fixed this, but Im not sure which of the following helped. Certainly one of them has!

I disabled indexing on the second drive
(I dont think this fixed it as I done a search afterwards and it was still slow)

I then changed the view in file explorer:

I went to the Ribbon and set:
Preview pane on
Set the icon view to details
Set the Group by (I feel this may have been the key) name
I set the columns to only: Name, Date, Size

Once I had set a group by the files display as they did on windows 7 the response is vastly different. I can open the windows file explorer each time and the response is as I would expect.

I havent rebooted to check this is a firm fix. But so far so good.

It is painfully slow navigating from folder to folder.

I would like Windows Explorer to operate as fast or even faster than Windows 7.

You write about upgrade. But even if you clean install, there is same issue.
My hardware: 3rd gen. Core i5, Q77 chipset, SATA3 SSD, 8 GB RAM

May be first fix is ruled out as I have only one C drive, pending purchase of 3TB HDD, as for indexing I have to keep indexed something at least on this only drive in order to work faster (!)

This is absolutely a windows defender problem or windows security essentials. When I disable it from services, icons appear very fast. When enabled icons take "years" to appear. They must solve this problem and it has nothing to do with indexing

I have this exact same problem, but it only happens on shares, and stopping the Windows Defender service makes no difference.

 

I'm accessing them over gigabit Ethernet, so it's not a speed issue either, nor did it happen on any prior version of Windows.

 

If I view the shares in details view, then it loads really quick as you'd expect. If I change it to Tiles view (Which is what I like to see them in), then every folder you open takes forever to load the files within. Scrolling is also extremely slow and cumbersome. It's as though File Explorer waits until all the larger icons are cached or something, because after you've allowed it to load all the icons for that view size, it's a bit quicker, but still not as snappy as earlier versions of Windows (And might I add, totally unacceptable).

 

Oddly enough, I can have my view set to Tiles on local folders (system32 for example) and it's as fast as it should be, it's only networked folders that appear to have the problem, and unfortunately for me, that's where most of my files reside.

 

Grouping makes no difference in either location (Local or remote).

Try disabling windows defender or security essentials from services, then do a search with *.* at your network sharing folders or disks, wait to finish, do an indexing by type or something else and re-enable windows defender. This helped for me and did that for every disk on my system. Not network though.

In shares time is required to spin up drives, I know that and wait in this case. Is it not your case?

Disabling defender made absolutely no difference to my original problem
