Brand new Windows and I discovered that SourceTree registers some keys for explorer in the registry. However, it was broken. So I did this. I hope it helps.

```

Windows Registry Editor Version 5.00

[-HKEY_CLASSES_ROOT\Directory\Background\shell\Sourcetree]
[HKEY_CLASSES_ROOT\Directory\Background\shell\Sourcetree]
@="Open with SourceTree"
"Icon"="%LOCALAPPDATA%\\SourceTree
SourceTree.exe"

[HKEY_CLASSES_ROOT\Directory\Background\shell\Sourcetree\command]
@="\"%LOCALAPPDATA%\\SourceTree\\SourceTree.exe\" log -f \"%V\""

[-HKEY_CLASSES_ROOT\Directory\shell\Sourcetree]
[HKEY_CLASSES_ROOT\Directory\shell\Sourcetree]
@="Open with SourceTree"
"Icon"="%LOCALAPPDATA%\\SourceTree
SourceTree.exe"

[HKEY_CLASSES_ROOT\Directory\shell\Sourcetree\command]
@="\"%LOCALAPPDATA%\\SourceTree\\SourceTree.exe\" log -f \"%V\""

[-HKEY_CLASSES_ROOT\LibraryFolder\background\shell\Sourcetree]
[HKEY_CLASSES_ROOT\LibraryFolder\background\shell\Sourcetree]
@="Open with SourceTree"
"Icon"="%LOCALAPPDATA%\\SourceTree
SourceTree.exe"

[HKEY_CLASSES_ROOT\LibraryFolder\background\shell\Sourcetree\command]
@="\"%LOCALAPPDATA%\\SourceTree\\SourceTree.exe\" log -f \"%V\""
