Windows features many useful files meant to help your PC work faster. Among these files, there is the icon cache which keeps copies of each and every icon sample.

This will come in handy when Windows needs to create a certain type of file or improve the basic icon after an upgrade. Instead of using the original icon file, it takes a copy that was stored in the icon cache and thus, the task is completed much faster.

However, sometimes your PC may be slow, and this is because there are too many icons stored in the cache. To fix this problem, the best solution is to increase the icon cache size.

How can I increase the size of Windows 10’s icon cache?

1. Open the Run dialog by pressing the Win + R keys on the keyboard.

2. Type the command regedit in the text box and then press Enter. The Registry Editor window will open.

3. Navigate to the following key in the Registry:HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Explorer

navigate to the explorer key in regedit

4. Once you launch the Explorer section, you need to create a new String Value called Max Cached Icons, which will reveal the maximum allocated space for the icon cache.

5. The value you need to introduce is 4096 which is the equivalent of 4 MBs. This is an improvement to the 550 KBs which are offered by the default Windows settings.

Increasing the size to more MBs might result in a slow working Windows system, so the key point is to not go overboard.
