Windows


  • 解决Windows10英文版中文字体难看、时大时小、中文比英文小等问题
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink
  • 把 MSYH.TTC,Microsoft YaHei UI,128,96 MSYH.TTC,Microsoft YaHei UI放在Segoe UI，Tahoma，Microsoft Sans Serif的前面。
  • seelink1, link2, link3
  • chrome installation
  • chrome的proxy setting用的是windows system proxy setting，而公司的新电脑上system proxy是不可以更改的。在这种情况下，安装完chrome后是无法sync and install extension。可以用google-chrome –proxy-server=“socks://localhost:8080"的方式用命令行来设置chrome proxy，后就可以sync and install extension。
  • 公司电脑的政策是只有whitelist里的extension是可以安装的，可以用SwitchyOmega切换proxy
  • WSL
  • Windows 10 21H2里的wsl (Arch)默认还是wsl1，需要在setting ->Apps & feature -> Optional features -> more windows features里安装"windows subsystem for linux” (for WSL1) and “virtual machine platform” (for WSL2)
  • Arch by default is WSL1，可以先把老的ext4.vhdx改名，再把wsl1 convert to wsl2，然后再把old hvdx的文件名改回ext4.vhdx及可。
  • backup for new laptop
  • onedrive, outlook,edge, chrome都是cloud based的，不用特殊备份
  • netid里的老证书也可以从网上下载，不用备份
  • backup chrome SwitchyOmega配置, .wslconfig in $user$ folder
  • WSL(arch)需要把相关文件拷贝到onedrive里，安装完成后再copy出来。
  • 其它非onedriver folder backup: log
