卸载 Ubuntu 的旧版本内核可以释放磁盘空间并优化系统性能。以下是几种常见方法：

1. 自动卸载未使用的内核：

   • 打开终端，运行以下命令查看已安装的内核列表：

     dpkg --list | grep linux-image

   • 然后运行以下命令自动卸载未使用的内核：

     sudo apt autoremove --purge

2. 手动删除特定内核：

   • 首先运行以下命令查看当前正在使用的内核版本：

     uname -r

   • 确保不要删除当前使用的内核。接着运行以下命令列出所有已安装的内核：

     dpkg --list | grep linux-image

   • 使用以下命令删除指定版本的内核（替换 x.x.x-x 为实际版本号）：

     sudo apt purge linux-image-x.x.x-x-generic

   • 删除后，更新 GRUB 引导加载程序：

     sudo update-grub

   • 最后，重新启动系统。

3. 清理残留的配置文件：

   • 使用以下命令清除所有状态为 rc 的包：

     sudo dpkg --purge $(dpkg -l | awk '/^rc/{print $2}')

在操作之前，请备份重要数据，并保留至少一个旧版本内核以防万一。如果需要更详细的指导，可以参考这里或这里。

希望这些方法对你有所帮助！如果有其他问题，随时告诉我。 😊

1. Ensure go back to release preview build

Methd1:
按Win+R输入regedit打开注册表

定位路径：HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\UI\Selection

修改UIBranch值为ReleasePreview

修改ContentType值为Mainline

修改Ring和UIRing值为Retail

定位路径：HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability

修改BranchName值为ReleasePreview

修改ContentType值为Mainline

修改Ring值为Retail

重启系统后检查设置-更新-Insider Program是否变为Release Preview

1. Locate the particular version in the Microsoft Update Catalog and download the installer.
2. Extract ChannelManifest.json from the installer. Should be about 90 KiB.
3. Upload it to a web server so that you have a URI it could be downloaded from, say https://example.org/ChannelManifest.json.
4. Go to C:\Program Files (x86)\Microsoft Visual Studio\Installer and open the command line there.
5. Run setup update --channelId VisualStudio.17.Release --productId Microsoft.VisualStudio.Product.Community --channelURI "https://example.org/ChannelManifest.json". Feel free to add other parameters.
