1、首先，新建一文本文件，复制黏贴以下代码，保存，然后修改文件扩展名为reg，然后双击运行导入注册表。
Windows Registry Editor Version 5.00
;取得文件修改权限
[HKEY_CLASSES_ROOT\*\shell\runas]
@="管理员权限"
"Icon"="C:\\Windows\\System32\\imageres.dll,102"
"NoWorkingDirectory"=""
[HKEY_CLASSES_ROOT\*\shell\runas\command]
@="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
"IsolatedCommand"="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
[HKEY_CLASSES_ROOT\exefile\shell\runas2]
@="管理员权限"
"Icon"="C:\\Windows\\System32\\imageres.dll,102"
"NoWorkingDirectory"=""
[HKEY_CLASSES_ROOT\exefile\shell\runas2\command]
@="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
"IsolatedCommand"="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
[HKEY_CLASSES_ROOT\Directory\shell\runas]
@="管理员权限"
"Icon"="C:\\Windows\\System32\\imageres.dll,102"
"NoWorkingDirectory"=""
[HKEY_CLASSES_ROOT\Directory\shell\runas\command]
@="cmd.exe /c takeown /f \"%1\" /r /d y && icacls \"%1\" /grant administrators:F /t"
"IsolatedCommand"="cmd.exe /c takeown /f \"%1\" /r /d y && icacls \"%1\" /grant administrators:F /t"
2、下面的是恢复原始权限的。操作跟上面一样。
Windows Registry Editor Version 5.00
;恢复原始权限
[HKEY_CLASSES_ROOT\*\shell\runas-]
@="恢复原始权限"
"Icon"="C:\\Windows\\System32\\imageres.dll,101"
"NoWorkingDirectory"=""
; && takeown /f \"%1\"
[HKEY_CLASSES_ROOT\*\shell\runas-\command]
@="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /reset && cacls \"%1\" /e /r \"%%USERNAME%%\""
"IsolatedCommand"="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /reset && cacls \"%1\" /e /r \"%%USERNAME%%\""
[HKEY_CLASSES_ROOT\exefile\shell\runas2-]
@="恢复原始权限"
"Icon"="C:\\Windows\\System32\\imageres.dll,101"
"NoWorkingDirectory"=""
[HKEY_CLASSES_ROOT\exefile\shell\runas2-\command]
@="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /reset && cacls \"%1\" /e /r \"%%USERNAME%%\""
"IsolatedCommand"="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /reset && cacls \"%1\" /e /r \"%%USERNAME%%\""
[HKEY_CLASSES_ROOT\Directory\shell\runas-]
@="恢复原始权限"
"Icon"="C:\\Windows\\System32\\imageres.dll,101"
"NoWorkingDirectory"=""
[HKEY_CLASSES_ROOT\Directory\shell\runas-\command]
@="cmd.exe /c takeown /f \"%1\" /r /d y && icacls \"%1\" /reset && cacls \"%1\" /e /r \"%%USERNAME%%\""
"IsolatedCommand"="cmd.exe /c takeown /f \"%1\" /r /d y && icacls \"%1\" /reset && cacls \"%1\" /e /r \"%%USERNAME%%\""
3、这个是删掉上面添加的右键菜单
Windows Registry Editor Version 5.00
[-HKEY_CLASSES_ROOT\*\shell\runas]
[-HKEY_CLASSES_ROOT\exefile\shell\runas2]
[-HKEY_CLASSES_ROOT\Directory\shell\runas]
[-HKEY_CLASSES_ROOT\*\shell\runas-]
[-HKEY_CLASSES_ROOT\exefile\shell\runas2-]
[-HKEY_CLASSES_ROOT\Directory\shell\runas-]
