Crafting the script for Win11 with admin requirements

I need to write the script for Windows 11 that checks for admin privileges and elevates if needed. First, I’ll use a basic command to check admin access. If not, I'll relaunch the script with elevated permissions. Then I'll disable EPP, adjust Mouse settings, and update virtual memory. Some extra steps might be required for the current session. I'll also notify about the adjustments in acceleration curves, though I'll avoid changing them to be safe.

Setting pagefile and power plan with batch script

I need to disable automatic pagefile management and set a custom pagefile size using PowerShell commands. If the pagefile doesn’t exist, I’ll create one. For the power plan, I’ll use powercfg to duplicate the Ultimate Performance scheme and handle output. To keep things clean in the batch script, I'll write temporary tasks to PowerShell files.

Adjusting power settings with localized support

I'll run powercfg to duplicate the Ultimate Performance power plan and then query the GUID regardless of language. Using PowerShell’s regex, I’ll capture the GUID, then activate it and adjust settings. I'll disable PCIe ASPM and USB selective suspend, applying the changes to the active scheme for simplicity.

Following Microsoft recommendations for device power settings

I'll set USB selective suspend to 0, as per Microsoft's troubleshooting guidance, which corresponds to disabling it. I'll also set the disk idle timeout and processor settings to specific values, then commit these changes with powercfg /setactive. Finally, I'll verify by querying the registry to ensure everything aligns with expectations.

Providing script to set power plan and pagefile settings

I’ll create a batch script that checks pagefile settings and power plans. For pagefiles, I'll display settings using PowerShell, and for the power plan, I’ll use powercfg to show the active scheme. I'll provide instructions, mention the need for rebooting, and include a caution for laptops about power usage. The script sets the pagefile on the system drive and supports self-elevation for admin rights. I'll add helpful citations and a minimal explanation in the response.

Creating a batch script for pagefile and power plan setup

I'll create a batch script with several tasks. First, it will disable enhanced pointer precision, then set the pagefile to 1.5x the system RAM. After that, the script will try to add and activate the Ultimate Performance power plan, using PowerShell commands. If it fails to create, it will attempt to find an existing one. It will also handle user permissions and reboot prompts.

下面是一份 Windows 11 用的一键优化 .bat（会自动提权管理员），按你要求做：

  • 关闭鼠标“增强指针精度”（指针加速）
  • 将虚拟内存（pagefile）设置为 实际物理内存的 1.5 倍（初始=最大，单位 MB）
  • 添加并启用 “Ultimate Performance / 卓越性能”（这是 Windows 自带隐藏电源计划，很多 Win11 游戏优化教程/网友推荐用它来减少电源管理带来的微延迟）(How-To Geek)
  • 输出验证信息（注册表/WMI/电源计划查询）

注意：虚拟内存设置在“下次开机”创建/调整生效（WMI 也说明页文件参数在系统启动时用于创建）(Microsoft Learn)

说明（很短）

  • “增强指针精度”本质就是改 HKCU\Control Panel\Mouse 的 MouseSpeed/MouseThreshold1/MouseThreshold2 为 0。(tenforums.com)
  • 电源计划用的是 Windows 自带隐藏的 Ultimate Performance，常见启用方式就是 powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61。(Pureinfotech)
  • Ultimate Performance 被许多优化文章解释为减少电源管理“微延迟”，适合追求响应/性能（但更耗电更热）。(How-To Geek)

如果你希望脚本把“只在插电时启用这些激进设置、用电池时自动回到平衡”，我也可以给你加上 DC（电池）分支。
