① 文件上有一把锁，打不开。应该是被锁定了只有特定的电脑用户才能打开，我怎么解除打开文件谢谢大神们了
在开始菜单中找找，类似加密软件的东西，输入密码应该会有一个新的文件夹，只有在这个文件下面，加密的软件才能正常使用，
主要要找是用了什么加密软件，密码是多少。或者怎么破解密码，
一般新装的软件在开始菜单中会有特别的颜色提醒，很好找，或者一个一个看，不认识都点一下，在就看看加密文件上是否有提示，
剩下的密码问题只有自己解决了
② 如何让文件只能在指定的电脑里才能打开.
可以使用加密软件来实现 比如域之盾系统 将客户端安装在电脑上 由管理端设置加密策略 加密过的文件任何形式的非法外发传输 拷贝打开都是乱码 ，只有在安装过域之盾客户端的电脑上才可以正常打开加密过的文件 希望能帮助到你
③ 电脑如何设置只允许运行指定程序打开指定软件
在电脑左下方找到搜索框，输入gpedit.msc，然后点击回车键。展开用户配置-管理模板，找到系统，然后点击，在右侧对话框中找到只运行指定的windows应用程序。双击打开只运行指定的windows应用程序。勾选已启用，然后点击允许的应用程序列表后面的显示然后在任意允许运行的程序快捷键方式上方点击右键，选择属性。选择快捷方式选项卡，找到目标，在里面复制运行程序名称，如下图：切换到刚刚步骤4中点击显示打开的对话框，把复制的运行程序名称粘贴到值当中去。最后依次点击确定即可实现电脑设置只允许运行指定程序，打开指定软件。

⑤ 孩子用的电脑怎么设置只能使用指定程序win11
使用windows组策略解决。
首先，在电脑左下方找到搜索框，输入gpedit.msc，然后点击回车键。然后展开用户配置-管理模板，找到系统，然后点击，在右侧对话框中找到只运行指定的windows应用程序。双击打开只运行指定的windows应用程序。点击允许后面的显示然后在任意允许运行的程序快捷键方式上方点击右键，选择属性。选择快捷方式选项卡，找到目标，在里面复制运行程序名称，点击显示打开的对话框，把复制的运行程序名称粘贴到值当中去。最后以此点击确定。就设置成功了只允许运行指定的软件了。
⑥ 如何让一个软件只能在一个电脑上用
尝试读取一个本电脑的硬件，硬件不符合就无法打开
⑦ 如何让一个文件只能在指定电脑打开
如果你资料很值钱没用的。人家也会拿了去，的方法又不只是到其它电脑上使用，所谓截图、复制、什么的都可以。除非你的是一个软件，那你可以用加密的方式来控制。现在好多东西都共享的，如果人家真想要你的东西你做了保护也没用，人家也会找高手破解。
⑧ 怎么实现文件只能在指定的电脑上打开
您好，把文加上NTFS加密，但要求必须是电脑有NTFS分区，在那个区无所谓。在要加密的文件上点右键，属性高级，在加密内容以保护数据前选中，确定，这样就完成了加本机加密。同时文件变成绿色，这个文件在别的电脑上是不被识别的，无法打开。在本机上不受影响。
这个是最好的加密码了，按照你的要求，这种是最完美的。机子系统自身加密码。
