问题描述：第一次安装完好，电脑重启后，svn小图标消失不见。查看注册表，发现属于svn小图标的注册表都消失不见。
问题分析：删除杀毒软件（360），因为电脑安装了360，ShellIconOverlayIdentifiers 下面多了个 360注册表
解决办法1： 卸载360，
把下面拷贝下段代码，新建文件 xx.reg。然后运营文件，目的是吧svn图标资料写入到注册表
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShellIconOverlayIdentifiers] [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShellIconOverlayIdentifiers1TortoiseNormal] @="{C5994560-53D9-4125-87C9-F193FC689CB2}" [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShellIconOverlayIdentifiers2TortoiseModified] @="{C5994561-53D9-4125-87C9-F193FC689CB2}" [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShellIconOverlayIdentifiers3TortoiseConflict] @="{C5994562-53D9-4125-87C9-F193FC689CB2}" [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShellIconOverlayIdentifiers4TortoiseLocked] @="{C5994563-53D9-4125-87C9-F193FC689CB2}" [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShellIconOverlayIdentifiers5TortoiseReadOnly] @="{C5994564-53D9-4125-87C9-F193FC689CB2}" [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShellIconOverlayIdentifiers6TortoiseDeleted] @="{C5994565-53D9-4125-87C9-F193FC689CB2}" [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShellIconOverlayIdentifiers7TortoiseAdded] @="{C5994566-53D9-4125-87C9-F193FC689CB2}" [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShellIconOverlayIdentifiers8TortoiseIgnored] @="{C5994567-53D9-4125-87C9-F193FC689CB2}" [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShellIconOverlayIdentifiers9TortoiseUnversioned] @="{C5994568-53D9-4125-87C9-F193FC689CB2}" [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShellIconOverlayIdentifiersOffline Files] @="{750fdf0e-2a26-11d1-a3ea-080036587f03}"
解决办法2：运行svn安装文件，修复下svn
