请确保计算机端已打开连接窗口，再使用无线投屏功能。
在其他设备端（如手机、平板、其他计算机）中打开无线投屏模式，搜索投影设备为上述计算机名称，进行连接即可。

微软已经在10月5日发布了Windows 11正式版，很多朋友也已经升级了。不过对于Windows 11的一些新设计，并不是所有人都能适应的，例如新的右键快捷菜单，就不少朋友表示接受不了。
Windows 11的新右键菜单相比之前的旧款式，颜值上的确大有提升，不仅使用了Fluent Design设计语言，而且优化了文字排版，行间距更宽，便于阅读和触控。然而，Win11的右键菜单隐藏了很多选项，如果想要找到一些常用的功能，需要点击“显示更多选项”才能展开，这操作起来颇为麻烦。怎么办？今天就来给大家分享一些恢复Windows 11完整右键菜单的方法！
首先，通过修改注册表，我们就可以将Win11的右键菜单改为老样式。下面是具体的方法。
·运行“regedit”，开启注册表编辑器，定位到“HKEY_CURRENT_USER\SOFTWARE\CLASSES\CLSID”；
·接着，右键点击“CLSID”键值，新建一个名为{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}的项；
·右键点击新创建的项，新建一个名为InprocServer32的项，按下回车键保存；
·最后选择新创建的项，然后双击右侧窗格中的默认条目，什么内容都不需要输入，按下回车键。
保存注册表后，重启explorer.exe，即可看到右键菜单恢复成旧样式了。
如果想要恢复成为Windows 11的设计，那么删掉InprocServer32的项就可以了。
参照 Flutter 2.8.1本地化/国际化应用程序名称 可以实现 Android/macOS/iOS/Web 的应用名称相关的国际化。Linux 参考 Flutter 3.0实现Linux本地化/国际化。
那么在 Windows 应用上如何相同的功能呢？
下面我们探讨一下一个比较简单的解决方案，就是直接修改RC文件，这个方案适用于涉及到的语言类型不太多的情况。
Windows 代码编译，需要安装 Microsoft Visual Studio 2022 Community，但是不能直接使用 Microsoft Visual Studio 2022 Community 编辑 RC 文件，打开就会报错
|
1 |
fatal error RC1015: cannot open include flie 'winres.h' |
具体的操作方法如下：
我们假定工程的名字为 LanauageTest
首先在项目根目录下，执行
|
1 |
$ flutter build windows |
生成 build 目录，然后使用 Microsoft Visual Studio 2022 Community 打开 build\windows\LanauageTest.sln 文件。
接着在资源视图中找到字符串资源，选择默认的 StringTable ，然后右键选择 “插入副本”
虽然可以使用上面的操作来添加语言，但是只能作为参考，原因在于 Microsoft Visual Studio 2022 Community的 RC 文件编辑器在修改 LanauageTest.RC 文件的时候，把预定义的宏进行了展开，直接使用宏的实际值替代了宏本身，导致这些数据失去动态变化的能力。我们只能手工再编辑一次，恢复原来的宏才可以。
至于使用的话，可以通过 LoadString 加载定义的字符串资源，更详细参考 Using Resources。
在Windows 10上使用 Linux 子系统的时候，无法成功启用。根据官方文档 旧版 WSL 的手动安装步骤 之后，依旧没效果，反倒是VirtualBox无法进入系统了。
观察日志，报错信息如下：
Intel CPU

{timestamp} HM: HMR3Init: Attempting fall back to NEM: VT-x is not available {timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work... |
AMD CPU

1 2 |
{timestamp} HM: HMR3Init: Attempting fall back to NEM: AMD-V is not available {timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work... |
解决方案如下：
1.使用管理员启动命令行.
2. 执行如下命令:
|
1 |
bcdedit /set hypervisorlaunchtype off |
某些电脑需要额外执行如下命令:
|
1 |
DISM /Online /Disable-Feature:Microsoft-Hyper-V |
3. 重启电脑
支持的，所有开普勒架构的桌面显卡，都可以支持到4K分辨率的输出，包括GTX650等极端开普勒架构显卡。
以下是GTX760最新的官方参数：
从技术支持和特性描述可以看出，GTX760原生支持4K输出，当然也就包括了各个子生厂商生产出的各种GTX760。并且可以通过DP接口输出4K@60Hz，通过HDMI输出4K@24Hz~30Hz，HDMI下的刷新率不如DP是因为HDMI的版本带来的带宽问题，所以如果你连接的是60Hz刷新率的4K显示器，那么建议是用DP接口进行连接。
之所以一些品牌的GTX760没写支持4K，是因为在GTX760发布的时候，4K还并不盛行，所以一些产品的资料里就并没注明支持4K，后来这些资料也并未进行更新，所以可能会产生误导，实际上是支持的。
只是GTX760的4K游戏性能较弱，如果你打算用GTX760在4K下进行游戏，那么可能需要调低不少特效，才能保证一定的画面流畅度。
从2.10之后的版本，flutter已经正式支持构建Windows应用。不过距离实现全平台构建，还需要考虑很多问题，flutter构建的应用更加适合移动端的使用习惯，如果需要构建Windows应用，我的建议是使用一些适合桌面端的widget。
具体方法如下：
PowerShell输入如下指令（如下命令可以使用flutter config查看，2.10以上的版本默认开启）
|
1 2 3 4 5 6 |
flutter config --enable-windows-desktop # 其他平台 flutter config --[no-]enable-macos-desktop flutter config --[no-]enable-linux-desktop |
可以使用flutter doctor查看情况

则需要更新Flutter SDK到3.0.2以上的版本即可，如下：
|
1 |
$ flutter upgrade |
在项目地址输入如下指令
|
1 |
flutter create --platforms=windows[,macos,linux] . |
注意: 项目的名称必须是全小写，如果出现大小写则会报错
