.SYNOPSIS
|
|
Applies system-wide registry settings and power configuration (HKLM).
|
|
|
|
.DESCRIPTION
|
|
Sets machine-wide registry tweaks under HKLM that apply to all users. Disables
|
|
unwanted telemetry and cloud features, configures Edge policies, sets power plan
|
|
timeouts, and disables proxy auto-detect. Uninstalls the pre-installed OneDrive
|
|
consumer version via OneDriveSetup.exe /uninstall - intentional for a clean MSP
|
|
deployment baseline. No DisableFileSyncNGSC policy key is set, so M365 installation
|
|
can install and run its own OneDrive version without restriction.
|
|
|
|
.ITEMS
|
|
bypass-nro-oobe-bypassnro-1: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\OOBE\BypassNRO = 1. Bypasses the "Let's connect you to a network" OOBE screen. Enables offline Windows setup without forcing a Microsoft account login.
|
|
zakaz-auto-instalace-teams: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Communications\ConfigureChatAutoInstall = 0. Prevents Windows from auto-installing Teams Personal during OOBE or after Cumulative Updates.
|
|
zakaz-cloud-optimized-content: ContentDeliveryManager\DisableCloudOptimizedContent = 1. Stops Windows from pushing sponsored app suggestions, tips from Microsoft servers, and "Get even more from Windows" prompts.
|
|
zakaz-widgets-news-and-interests: HKLM\SOFTWARE\Policies\Microsoft\Dsh\AllowNewsAndInterests = 0. Disables the Widgets taskbar button and panel (news feed, weather, stocks). Not relevant for business deployments.
|
|
hesla-bez-expirace-net-accounts-maxpwage: net accounts /maxpwage:UNLIMITED. Sets the local password expiration policy to never. MSP-managed machines handle password rotation via other means (Atera, domain policy, manual).
|
|
casova-zona-central-europe-standard-time: Set-TimeZone -Id "Central Europe Standard Time". UTC+1 (UTC+2 in summer DST). Applied system-wide. Critical for correct log timestamps, scheduled task timing, and calendar sync.
|
|
zakaz-gamedvr: HKLM\SOFTWARE\Policies\Microsoft\Windows\GameDVR\AppCaptureEnabled = 0. Disables Xbox Game Bar screen capture overlay. Reduces background resource usage and eliminates unintended capture prompts on business machines.
|
|
edge-skryt-first-run-experience: HideFirstRunExperience=1 + DefaultBrowserSettingEnabled=0. Suppresses Edge welcome wizard and default browser prompts on first launch.
|
|
edge-policies-panel-oblibeny-vyhledavac: FavoritesBarEnabled=1 (always show), DefaultSearchProviderEnabled=1, DefaultSearchProviderName=Google, ManagedSearchEngines removes other providers.
|
|
edge-policies-tlacitka-zobrazit: DownloadsButtonEnabled=1, HistoryButtonEnabled=1.
|
|
edge-policies-tlacitka-skryt: HomeButtonEnabled=0, SplitScreenEnabled=0, EdgeEDropEnabled=0 (Drop), WebCaptureEnabled=0 (Screenshot), ShareAllowed=0.
|
|
edge-policies-obsah-a-telemetrie: NewTabPageContentEnabled=0, ShowRecommendationsEnabled=0, SpotlightExperiencesAndRecommendationsEnabled=0, PersonalizationReportingEnabled=0, EdgeShoppingAssistantEnabled=0, ShowMicrosoftRewards=0, HubsSidebarEnabled=0, SearchSuggestEnabled=0, DiagnosticData=0, FeedbackSurveysEnabled=0, EdgeCollectionsEnabled=0.
|
|
onedrive-uninstall-intentional: Uninstalls the pre-installed OneDrive consumer version via OneDriveSetup.exe /uninstall and removes Start Menu shortcut. Intentional for clean MSP deployment baseline. No DisableFileSyncNGSC policy key is set - M365 installation can reinstall and run OneDrive normally. Only the stock consumer pre-install is removed.
|
|
powercfg-nastaveni-spotreba-energie: powercfg /change commands: standby-timeout-ac 0 (never sleep on AC/charger), monitor-timeout-ac 60 (screen off after 60 min on AC), standby-timeout-dc 30 (sleep after 30 min on battery), monitor-timeout-dc 15 (screen off after 15 min on battery).
|
|
proxy-auto-detect-zakaz-autodetect-0: HKLM\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\AutoDetect = 0. Disables WPAD (Web Proxy Auto-Discovery). Eliminates startup delays from WPAD DNS lookup and prevents potential MITM via malicious WPAD responses on untrusted networks.
