Explorer is acting oddly in Windows 10.
When opening File Explorer, the thumbnails for .jpg files disappear. Some folders cause the application to consume up to 30% CPU (I3-10100) for about half a minute before returning to normal. Why is this happening now? Yesterday it worked fine, but what changed? I’ve run two full scans and the antivirus still reports no threats.
When dealing with a folder full of files, it needs to load and show them all, which can put a lot of strain on your CPU. If your previews are missing, you'll find this option available at the top, and it also works on Windows 10. It's labeled as "view" in the dropdown menu. Select the size you prefer using the icons.
I indicated this condition. Big files can trigger it too. For instance, I pasted my OS folder multiple times, yet there were 20 files each with substantial size. I shared a brief clip to illustrate. Now I have a quicker CPU, but you'll see the consumption rise, especially on slower drives and it could significantly affect performance while handling 1486637158_2021-10-3009-54-32.mp4
You're intentionally doing the opposite of what you intend. The tool is actually loading itself again because it's a built-in Windows process. You can't have both your preferences and the default behavior satisfied at once. Decide whether you want your thumbnails or if you're okay with the lag. If the performance is too slow, you can force it to show icons in the fourth screenshot of my previous message.
Essentially, everything I understand is that once I completed that action, thumbnails reappeared and File Explorer functioned normally again.
This occurs because the COM Surrogate doesn't load within the expected time limit, often because of permission issues or damaged indexing data. The first scenario is unlikely since these delays tend to stay consistent when the issue stems from incorrect permissions. Likely, something like a corrupted thumbnail file on your drive is causing the problem. If it happens again, using tools such as Glary Utilities to clear the thumbnail cache might help. Windows Cleanup can also assist, though it may be outdated since it comes from around 1990.
