    Windows explorer: Thumbnails take a long time to generate


    Hello everyone.

    I recently noticed that it would take Windows a long time to generate the thumbnails in Windows Explorer when there are sub-folders a couple of levels deep. If there are no sub-folders or sub-folders just one level deep, then the thumbnails would instantly load.

    I can click on a folder and then wait for the green bar to slowly go across the screen, often time, it would take minutes. All thumbnails would eventually be shown, but that is an awfully long time. If I scroll down, the next set of thumbnails would then take a long time to load. If I scroll back up, it would take a long time to reload those thumbnails again. During the time of the loading, the CPU fan would rev to max and is very loud.

    I've combed the web and this forum for answers. I've deleted the thumbnail cache. Another thread said to disable the Windows search service, but I use that a lot to locate files and pictures on my PC.

    At first, I thought it was my new SSD failing already, because that usually happens when one of my hard drive fails. I get the same results copying the files and directory structures to a RAM drive. On folders with multiple directories deep, it would take a long time to load the thumbnails there too.

    There was an update that requires a reboot two days ago and I believe it is what caused the issue. According to Windows, it is the latest update pending the feature update one.

    Windows version 1909
    OS Build: 18363.959
    CPU: Zeon E3-1505 v5
    Ram: 64GB

    Any recommendations would be greatly appreciated. I work with images and documents so rely on Windows Explorer. Until now, I did not have this issue.

    Thank you.

    How many files are we talking about? The cache is there to speed it up but it has to read a lot from disk does it work fast if you go back a second time?

    Thank you for the reply.

    There are around 30-40 files in each directory top level directories that I tried to access. The many subdirectories have a lot less files, maybe 5-20. The subdirectories go only 4 level deep. This is from an SSD and also RAM drive.

    I don't understand how one of the cores of the Zeon CPU would spike and the fan go to MAX just accessing those directories.
