To begin, first create a system restore point. Should something go wrong, you will be able to restore your computer back to this point.

Having done that, open WinX Menu and select Run. Type regedit and hit Enter to open the Registry Editor.

Now navigate to the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer

Now right-click and create a new REG_SZ (String Value) and name it Max Cached Icons.

Give it a value of 4096 (4MB) or 8192 which is 8MB.

Save and exit the Registry Editor and restart your computer.

See if this gives you positive results.

If the results are not to your expectation, you may delete the created REG_SZ (String Value) or change its value to 500, which is the default value. You may also restore your computer to the created restore point, if you wish.
