删除 Windows 11 中资源管理器左侧的主文件夹和图库

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Classes\CLSID\{e88865ea-0e1c-4e20-9aa6-edcd0212c87c}]
"System.IsPinnedToNameSpaceTree"=dword:00000000

解决打开游戏时出现“无法打开此“ms-gamingoverlay“链接”弹窗问题

打开运行（Win+R），并输入 regedit 命令，按确定或回车
定位如下位置：

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\GameDVR

找到 AppCaptureEnabled 这个键值，把值改为 0

定位如下位置：

HKEY_CURRENT_USER\System\GameConfigStore

找到 GameDVR_Enabled 这个键值，把值改为 0

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：

netsh interface ipv6 show prefixpolicies

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：

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：

Querying active state...

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

Windows 10/11 的访问前缀规则参照 RFC6724: Default Address Selection for Internet Protocol Version 6 (IPv6) 实现。可参考 IANA IPv6 Special-Purpose Address Registry 查看这些前缀的归属。

一些优化

请在管理员权限的终端中运行

禁用动态时钟

禁用动态时钟可以减少系统中断，提升性能稳定性：

bcdedit /set disabledynamictick yes

禁用最后访问时间戳

禁用 NTFS 文件系统的最后访问时间戳更新，减少磁盘写入：

fsutil behavior set disableLastAccess 1

禁用 8.3 短文件名

禁用 NTFS 的 8.3 短文件名生成，提升文件系统性能：

fsutil behavior set disable8dot3 1

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

Get-MpPreference | select ScanAvgCPULoadFactor

调整 CPU 占用比例，例如设置为 20

Set-MpPreference -ScanAvgCPULoadFactor 20

关闭映射磁盘文件扫描

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

首先在管理员终端中关闭 Hyper-V

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 Hyper-V 以及相关服务

关闭内存完整性

关闭 Device Guard

进入注册表

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard

EnableVirtualizationBasedSecurity = 0
RequirePlatformSecurityFeatures = 0

关闭 Credential Guard

进入注册表

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

LsaCfgFlags = 0

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceGuard

LsaCfgFlags = 0

进入管理员 CMD

bcdedit /set vsmlaunchtype off
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,DISABLE-VBS
bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X:
mountvol X: /d

重启电脑后会提示关闭 Credential Guard，按 Win + F3 确认

参考：https://learn.microsoft.com/zh-cn/windows/security/identity-protection/credential-guard/configure?tabs=reg

安装开启 Hyper-V

pushd "%~dp0"
dir /b %SystemRoot%\servicing\Packages\*Hyper-V*.mum >hyper-v.txt
for /f %%i in ('findstr /i . hyper-v.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i"
del hyper-v.txt
Dism /online /enable-feature /featurename:Microsoft-Hyper-V-All /LimitAccess /ALL

重新编译 .NET Framework 机器码

$env:PATH = [Runtime.InteropServices.RuntimeEnvironment]::GetRuntimeDirectory()
[AppDomain]::CurrentDomain.GetAssemblies() | ForEach-Object {
    $path = $_.Location
    if ($path) {
        $name = Split-Path $path -Leaf
        Write-Host -ForegroundColor Yellow "`r`n$name"
        ngen.exe install $path /nologo
    }
}

清除图标缓存

taskkill /f /im explorer.exe
cd /d %userprofile%\AppData\Local\Microsoft\Windows\Explorer
attrib -h iconcache_*.db
del iconcache_*.db /a
cd /d %userprofile%\AppData\Local
del IconCache.db /a
start explorer.exe
echo 执行完成

安装开启组策略

@echo off
pushd "%~dp0"
dir /b C:\Windows\servicing\Packages\Microsoft-Windows-GroupPolicy-ClientExtensions-Package~3*.mum >List.txt
dir /b C:\Windows\servicing\Packages\Microsoft-Windows-GroupPolicy-ClientTools-Package~3*.mum >>List.txt
for /f %%i in ('findstr /i . List.txt 2^>nul') do dism /online /norestart /add-package:"C:\Windows\servicing\Packages\%%i"
pause

        [switch]$Force
    )

    begin {
        $shell = New-Object -ComObject Shell.Application
    }

    process {
        foreach ($itemPath in $Path) {
            $resolvedPaths = Resolve-Path -Path $itemPath -ErrorAction SilentlyContinue

            if (-not $resolvedPaths) { continue }

                        Write-Error "项 $fullPath 包含项，若要删除，请指定 -Recurse 参数。"
                        continue

                }
