Windows 使用笔记
解决 ping localhost 时为 ipv6 地址
解决方法
请在管理员权限的 cmd 或 powershell 中运行
先查一下前缀优先级：
powershell
netsh interface ipv6 show prefixpoliciestext
Querying active state...
Precedence Label Prefix
---------- ----- --------------------------------
50 0 ::1/128
40 1 ::/0
35 4 ::ffff:0:0/96
30 2 2002::/16
5 5 2001::/32
3 13 fc00::/7
1 11 fec0::/10
1 11 3ffe::/16
1 3 ::/96上面的输出中 ::/0 是 ipv6 的前缀，需要调低优先级，低于 ::ffff:0:0/96 ::/96 这些 ipv4 的前缀即可。
依次执行：
powershell
netsh int ipv6 set prefix ::/96 50 0
netsh int ipv6 set prefix ::ffff:0:0/96 40 1
netsh int ipv6 set prefix 2002::/16 35 2
netsh int ipv6 set prefix 2001::/32 30 3
netsh int ipv6 set prefix ::1/128 10 4
netsh int ipv6 set prefix ::/0 5 5
netsh int ipv6 set prefix fc00::/7 3 13
netsh int ipv6 set prefix fec0::/10 1 11
netsh int ipv6 set prefix 3ffe::/16 1 12再次查询：

Precedence Label Prefix
---------- ----- --------------------------------
50 0 ::/96
40 1 ::ffff:0:0/96
35 2 2002::/16
30 3 2001::/32
10 4 ::1/128
5 5 ::/0
3 13 fc00::/7
1 12 3ffe::/16
1 11 fec0::/10前缀含义
Windows10/11 的访问前缀规则参照 RFC6724: Default Address Selection for Internet Protocol Version 6 (IPv6) 实现。
可参考 在 IANA IPv6 Special-Purpose Address Registry 查看这些前缀的归属。
优化 Windows Defender 性能
设置扫描占用的 CPU 比例
查看当前的 CPU 占用比例，默认一般是 50
powershell
Get-MpPreference | select ScanAvgCPULoadFactor调整 CPU 占用比例，例如设置为 20
powershell
Set-MpPreference -ScanAvgCPULoadFactor 20关闭映射磁盘文件扫描
powershell
Set-MpPreference -DisableScanningNetworkFiles 1
Set-MpPreference -DisableScanningMappedNetworkDrivesForFullScan 1彻底关闭 Hyper-V、WSL、Device Guard、Credential Guard
关闭下列基于虚拟化的相关服务和模块以提升性能
注意： WSL2、Docker Desktop、Podman Desktop 等基于 Hyper-V 的软件将无法工作
反正我不用这些软件
关闭 Hyper-V 以及相关服务
首先在终端管理员中关闭 Hyper-V
powershell
Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Hypervisor
bcdedit /set hypervisorlaunchtype off再进入 Windows 功能关闭其他功能
关闭内存完整性
关闭 Device Guard
进入注册表

EnableVirtualizationBasedSecurity = 0
RequirePlatformSecurityFeatures = 0关闭 Credential Guard
进入注册表

LsaCfgFlags = 0text
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceGuard
LsaCfgFlags = 0进入管理员 CMD
cmd
mountvol X: /s
copy %WINDIR%\System32\SecConfig.efi X:\EFI\Microsoft\Boot\SecConfig.efi /Y
bcdedit /create {0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloader
bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi"
bcdedit /set {bootmgr} bootsequence {0cb3b571-2f2e-4343-a879-d86a476d7215}
bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} loadoptions DISABLE-LSA-ISO
bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X:
mountvol X: /d禁用基于虚拟化的安全性
删除下列注册表项

bcdedit /set vsmlaunchtype off重启电脑后会提示关闭 Credential Guard，按 Win + F3 确认
安装开启 Hyper-V
cmd

Write-Host -ForegroundColor Yellow "`r`n$name"
ngen.exe install $path /nologo
}
}清除图标缓存
cmd
taskkill /f /im explorer.exe
