Windows 7 Slow to Thumbnail Preview – Solution

We have found for the problem that we have experienced significantly with Windows 7. The problem is found when viewing in Thumbnail Preview a directory with a lot of image files in it.

Like you would a directory of icon images used in a graphic design company, or even a general user with a lot of images in your folder.

What happens is that the system stalls and chokes while a green progress bar slides from left to right taking anything up to 40 seconds to complete.


While the thumbnails are not displayed, but the default icon is in place while the computer has a good old think about that it will do next.

Strangely enough, this was something that worked well on the Microsoft Windows India (AKA Vista). Some how the US boys broke the thing when they took the code back from the Indians to pump out Vista (Rebranded Windows 7).

You can see where I am going with this… or at least can tell that I am completely fed up with the fact that massive computer system running a RAID Stripe with 3 of the fastest hard disks on the market, struggles to generate thumbnails from a file that the operating system has already created and hidden.

When my old iPhone 3 generates icons as fast as I can view them.

So that got me thinking how I can fix this.

Got me thinking back to solutions from Windows 95 days. There were thumbnail generating programs back then that worked faster than Windows 7.

Even had me thinking about breaking things apart into folders with less files in it.

But then it came to me….

The fix.

I am a proud mac owner. What the hell am I busting my hump trying to work out how to fix a problem that Microsoft created and never fixed since the release of Windows 7. I should stop thinking like a Windows Server Administrator and think like a user.

So User… what you going to do.

1. You already have Drop Box syncing the files since Microsoft Killed the pleasure you once had with Folder Share / Live Sync / (Some Busted Ass junk that no longer works since MS purchased Folder Share).

2. The directory is already on the mac, because Drop Box just works!

3. Just surf the images on the Mac.

What a pleasure. The experience was so good, that I just played with it fir 10 min or so, seeing how fast I could scroll and see if it could keep up. It could.

I went from this:

Solution found!  (I had to write this because it ticks me off so much that the basic features of Windows Still don’t work after soooo long!)

Thumbnail Generation is just one of many.

    1. Fair enough comment. Bet you can’t find a fix for this in Windows 7. There is not one. Known problem to do with the inherent search feature! Crap that after 4 years + they have not patched it.

  1. solution is to disable taskoffload in ip settings (netsh int ip set global taskoffload=disabled) and eventually you can customize the folder properties to match “pictures” (from the windows explorer right clic)… That’s it !
    try it, thumbs will load much faster. Ciao
