Task bar icons/thumbnails appears smaller than usual

Thanks for reaching out. Let’s try to fix this together.

First, a few quick questions to narrow this down

1. Are you using Windows 10 or 11?
2. Did this start happening after a recent update or driver install?
3. Are you using any scaling or custom display settings under Settings > System > Display?
4. Are you using multiple monitors or a high-DPI screen in 4K, etc.?

Try these steps for now

Step 1) Go to Settings > System > Display

Set the scale to 100% or 125%; don’t use custom scaling yet

Sign out and sign back in after applying

Step 2) Rebuild icon cache

Open Command Prompt as admin

Run these one by one:

taskkill /IM explorer.exe /F

cd /d %userprofile%\AppData\Local

del IconCache.db /a

start explorer.exe

Step 3) Check for DPI settings per app

Right-click the Armoury Crate shortcut > Properties

Go to Compatibility > Change high DPI settings

Check Override high DPI scaling behavior and set it to Application

Click OK and relaunch

Step 4) This is an advanced fix; we will need to access the Windows registry.

Note: Back up your registry first (File > Export in regedit). Be very careful when editing the registry; incorrect changes can cause system issues.

Press Win + R, type regedit, and press Enter

Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

Right-click in the right pane > New > DWORD (32-bit) Value

Name it: TaskbarSi

Set the value: 0 = small, 1 = medium (default), 2 = large

Restart your PC

Let me know what happens after trying these. We’ll take the next step if needed.
