How do I fix TortoiseSVN displaying random icon overlays?

Question

I use TortoiseSVN (latest version) and sometimes all the icon overlays it uses get randomized with quite peculiar results. Is there any way to fix this?

Answer 1

From the TortoiseSVN FAQ:

Why do the overlay icons sometimes change to random graphics?

The Windows icon cache is a fairly buggy creature. You can solve this in one of the following ways:

• Install Microsoft's TweakUI and run the option to rebuild icons.

• Or increase the icon cache size. Go to HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows>\\CurrentVersion\\Explorer and add a new String Value called Max Cached Icons. The default value is 500 - try increasing it to 2048 (see Q132668 in the Microsoft knowledge base for more details).

• Or delete the file called ShellIconCache in your Windows directory. And reboot.

• With TortoiseSVN 1.3.0 and later, you can also rebuild the icon cache by calling TortoiseProc from the command line like this TortoiseProc.exe /command:rebuildiconcache

Answer 2

Found a solution:

Using Registry Editor, add a Max Cached Icons string value with a value data of 2000 to the following registry key, and then restart your computer:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer
