ApplicationPoolMemory - use 0 instead of 4096
Also:
* Make the following "Advanced Settings" for WSUS Application Pool in IIS:
- Queue Length: 25000 from 10000
- Limit Interval (minutes): 15 from 5
- "Service Unavailable" Response: TcpLevel from HttpLevel
* Edit the web.config ( C:\Program Files\Update Services\WebServices\ClientWebService\web.config ) for WSUS (Stop the IIS first):
- Replace <httpRuntime maxRequestLength="4096" /> with <httpRuntime maxRequestLength="204800" executionTimeout="7200"/>

function New-IsoFile { <# .Synopsis Creates a new .iso file .Description The New-IsoFile cmdlet creates a new .iso file containing content from chosen folders .Example New-IsoFile "c:\tools","c:Downloads\utils" This command creates a .iso file in $env:temp folder (default location) that contains c:\tools and c:\downloads\utils folders. The folders themselves are included at the root of the .iso image. .Example New-IsoFile -FromClipboard -Verbose Before running this command, select and copy (Ctrl-C) files/folders in Explorer first. .Example dir c:\WinPE | New-IsoFile -Path c:\temp\WinPE.iso -BootFile "${env:ProgramFiles(x86)}\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\amd64\Oscdimg\efisys.bin" -Media DVDPLUSR -Title "WinPE" This command creates a bootable .iso file containing the content from c:\WinPE folder, but the folder itself isn't included. Boot file etfsboot.com can be found in Windows ADK.

Отсутствие схем электропитания вероятнее всего связано с новым режимом питания на устройствах с аккумулятором в версии 1709 . Если щелкнуть значок батареи, то можно видеть слайдер, который появится только, если выбрана схема «Сбалансированная».
Схемы можно восстановить следующими способами: сделать схему «Высокая производительность» или «Экономия энергии» активной, при этом активная схема появится в Панели управления, или же создать дубликаты этих схем, и тогда появятся обе схемы. В Командной строке нужно выполнить команды.
Сделать схему активной: powercfg.exe /setactive <GUID схемы питания>
Создать дупликат схемы: powercfg -duplicatescheme <GUID схемы питания>
Вместо <GUID схемы питания> нужно вставить GUID соответствующей схемы.
Для схемы "Сбалансированная" - 381b4222-f694-41f0-9685-ff5bb260df2e
Для схемы "Экономия энергии" - a1841308-3541-4fab-bc81-f71556f20b4a
Для схемы "Высокая производительность" - 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c
