一款简单实用的应用程序加密软件,当用户不想其他人使用电脑上的应用程序,用户就能够使用该软件将其应用程序进行加密处理,这样就能在两个或两个以上的人使用与你同一台计算机时,保护其中需要加密的隐私。软件能够在电脑上帮助用户以密码来保护任何可执行的文件,以防止其他使用该电脑的用户未经授权执行,这是用户能够在共享环境中提高安全性的一种方法。并且,当用户在使用软件木马,病毒,间谍软件和其他恶意软件都不会破坏或破坏加密后的计算机数据和文件,能够很好的保护用会的电脑,提高它的使用寿命。除此之外,用户使用此轻量级工具,能够为用户们提供安全的上网环境,可以轻松保护自己的隐私,远离身份盗用或欺诈。

Logitech K380蓝牙键盘,默认最顶上一排键是各种快捷功能。用Logitech的软件可以改成默认F1~F12。但是为了改个Fn键,装200M软件也太那什么了。 此程序可用C#编译,在Windows下运行,找到K380键盘后,写入相应的指令,打开Fn锁定功能,最顶上一排键默认为F1~F12。 运行该程序接上键盘每三秒会试探蓝牙键盘是否存在,如果存在,则自动设置f1~f12启用。 若想关闭,可以关闭程序,重新连蓝牙键盘即可.代码来源于:https://github.com/hediet/K380-function-keys-enabler ,稍有改动。
