Windows 10 20H2更新时总是报0xc1900204错误的解决

我的台式机Windows 10版本是20H2，再往后更新的时候总是失败，困扰两年了，其间在网上找了很多方法，基本上都说是windows update服务有问题了，重置一下、删除临时文件等办法，照着做了毫无作用。近日突然想起来用英文搜了一下，总算有所突破，终于解决了多年顽疾，成功更新到最新的22H2。

这一问题其实是Win10不知道哪一次更新时带来的一个bug，主要是内部标识的版本号错误，但这一问题始终没有解决。

解决方法就是在注册表编辑器中找到HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionVersion这个键，修改两个值：

  • “EditionBuildNumber”=dword:00004a62 ==> 把4a62 改成 4a61.
  • “EditionBuildQfe”=dword:0000023c ==> 改成1fc
  • 改完后如下图

3、安装chrome浏览器

xset s noblank
xset -dpms

# Allow quitting the X server with CTRL-ATL-Backspace
setxkbmap -option terminate:ctrl_alt_bksp

# Start Chromium in kiosk mode
sed -i 's/"exited_cleanly":false/"exited_cleanly":true/' ~/.config/chromium/'Local State'
sed -i 's/"exited_cleanly":false/"exited_cleanly":true/; s/"exit_type":"[^"]\+"/"exit_type":"Normal"/' ~/.config/chromium/Default/Preferences

DCS里面增加可以绑定的轴控制

I find that the A-10C lua files (like those of the KA-50) do not work with the mnemomic device and command ID. You have to use the numerical ones.

The code below creates an axis command for the UHF radio volume knob:
Code:

{action = 3011, cockpit_device_id = 54, name = _('UHF Radio Volume')},

The device ID for the UHF Radio is 54 as you can see in “devices.lua”. The command ID is 3011. You find the command as “device_commands.Button_11” in “clickabledata.lua”. So it’s button 11 of device 54. However, as you see in “command_defs.lua”, all device command numbers are defined as 3000 + Button-Number.
Note: The axis uses only half of the slider movement. You have to define parameters in Axis Tune to use the full slider movement or pot rotation. That’s a common problem in custom axis definitions.
Have fun!
