Some, but not all, icons for UWP apps are not displaying in search or settings. They do, however, display on the start menu when not searching. Icons for all non UWP apps display correctly, every time. UWP app icons are always present on the taskbar.
UPDATE: Many locally stored image thumbnails fail to appear in start menu search results either, no matter what image format.
The reason I have posted this as a separate question from this thread, is for the following differentiating reasons:
- Not all UWP app icons fail to display
- The issue is specifically present on the start menu only during search
- UWP apps never fail to display their icons on the taskbar
I have tried:
- Resetting the icon cache
- The solution here involving the windowsapps folder
- Creating a new user account
- Deleting iconstream registry keys
-
Changing performance settings to save thumbnails
-
Changing default app for PNGs
- Changing default app for all images in windows settings
- Changing windows explorer view settings
- Updating graphics drivers

For years, I've had the exact same issues with app thumbnails. Particularly for Metro-style apps (RT/UWP), I often see a blank or default icon, primarily in search results and settings. I've been troubleshooting it for years, with no success until now. I'm documenting this here because I know I'm going to encounter it again. When I search for a solution, I'll hopefully find this page.
Background
In Windows 10, UWP apps are shipped as AppX packages. This includes many of the new built-in apps (stored in
%SystemRoot%\SystemApps
) as well as apps downloaded via Windows Store (stored in%ProgramFiles%\WindowsApps
). PowerShell offers several cmdlets that are useful for managing AppX packages. Throughout my troubleshooting, I found Get-AppxPackage, Add-AppxPackage, and Remove-AppxPackage particularly useful, especially since%ProgramFiles%\WindowsApps
is inaccessible to normal users, even administrators.Before attempting these fixes, you should be comfortable editing the registry, working with the command prompt and PowerShell, and making backups. You should be prepared to wipe everything and reinstall Windows should something go wrong.
Issue 1: Third-party thumbnail handlers for .png
Some third-party apps like to install custom thumbnail generators. Some of these apps do so in a way that breaks things. In my case, Google's Drive File Stream was the culprit. Keep in mind that this is different from having a default program for a file; Windows Photos remained the default for me. To solve the issue:
regedt32.exe
HKEY_CLASSES_ROOT\.png
ShellEx
key with at least one subkey. If you see any subkeys, you've probably found the culprit.Here's a screenshot of what you should be deleting. Note that the actual key might not be named
{E357FCCD-A995-4576-B01F-234630154E96}
; it'll depend on the application responsible for the issue.This may seem like an obscure fix, but the issue stems from the fact that AppX package logos are typically stored as PNG files. When this issue arises, you may also notice that PNG files are lacking proper thumbnails (you won't see previews while browsing folders in File Explorer). If the app causing the problem has installed similar handlers for other image file types, you can perform the same steps as above to the affected file extensions to restore the thumbnails. Keep in mind that this may affect the functionality of the app, so you may have to make a trade-off.

Issue 5: Windows Settings Sync
I've heard that Windows Settings Sync has caused issues with icons for some people. I haven't been able to reproduce this, but you can check whether it's the issue by disabling it temporarily. It's likely that there's either some underlying setting that's the true culprit; it may be resulting in bad icons being uploaded. Reportedly, this primarily affects search results in Cortana and the Start menu.

Issue 7: Low disk space
Unsurprisingly, if your drive is almost full, File Explorer will have issues saving thumbnails and will be rather unhappy about it. The solution here is to clear some space. Simple enough.
Issue 8: Windows is borked, proceed to panic
Anytime someone mentions this problem on Microsoft Answers, a Microsoft rep always recommends the same solution. I've never heard of it working for anyone, but it can't hurt to try. (Besides, if you contact Microsoft, they're going to tell you to do it anyway.) It could theoretically fix certain obscure issues.
