[QUOTE="ForgottenSeer 85179, post: 920296"] Which needs admin rights! Unfortunately I forgot to write that. After some time i play again with these settings and remove "Block untrusted fonts" because [URL='https://techcommunity.microsoft.com/t5/microsoft-security-baselines/dropping-the-quot-untrusted-font-blocking-quot-setting/ba-p/701068']Dropping the "Untrusted Font Blocking" setting - Microsoft Tech Community[/URL] I also test these settings: # Export address filtering (EAF): Detects dangerous operations being resolved by malicious code with and without: optionally validate access by modules commonly used by exploits enabled # Import address filtering (IAF): Detects dangerous operations being resolved by malicious code. # Validate stack integrity (StackPivot): Ensures that the stack hasn't been redirected for sensitive APIs. Not compatible with ACG # Validate API invocation (CallerCheck): Ensures that sensitive APIs are invoked by legitimate callers. Only configurable for 32-bit (x86) applications. Not compatible with ACG # Simulate execution (SimExec): Ensures that calls to sensitive APIs return to legitimate callers. Only configurable for 32-bit (x86) applications. Not compatible with ACG None of them are compatible with AdGuard extension and sites are broken (maybe do to extension or because of configured encrypted DNS i don't know) So no changes are required (y) [U][B]Edit:[/B][/U] here also the XML file for maximum Edge settings with default OS settings (from 20H2 Windows build): [SPOILER="DefaultOS+MaximumEdge.xml"][CODE=xml]<?xml version="1.0" encoding="UTF-8"?> <MitigationPolicy> <AppConfig Executable="ExtExport.exe"> <ASLR ForceRelocateImages="true" RequireInfo="false" /> </AppConfig> <AppConfig Executable="ie4uinit.exe"> <ASLR ForceRelocateImages="true" RequireInfo="false" /> </AppConfig> <AppConfig Executable="ieinstal.exe"> <ASLR ForceRelocateImages="true" RequireInfo="false" /> </AppConfig> <AppConfig Executable="ielowutil.exe"> <ASLR ForceRelocateImages="true" RequireInfo="false" /> </AppConfig> <AppConfig Executable="ieUnatt.exe"> <ASLR ForceRelocateImages="true" RequireInfo="false" /> </AppConfig> <AppConfig Executable="mscorsvw.exe"> <ExtensionPoints DisableExtensionPoints="true" /> </AppConfig> <AppConfig Executable="msedge.exe"> <DEP Enable="true" EmulateAtlThunks="true" /> <ASLR ForceRelocateImages="true" RequireInfo="true" BottomUp="true" HighEntropy="true" /> <StrictHandle Enable="true" /> <ExtensionPoints DisableExtensionPoints="true" /> <ControlFlowGuard Enable="true" SuppressExports="false" /> <SignedBinaries MicrosoftSignedOnly="true" AllowStoreSignedBinaries="true" Audit="false" AuditStoreSigned="false" EnforceModuleDependencySigning="true" /> <ImageLoad BlockRemoteImageLoads="true" AuditRemoteImageLoads="false" BlockLowLabelImageLoads="true" AuditLowLabelImageLoads="false" /> <SEHOP Enable="true" TelemetryOnly="false" /> <Heap TerminateOnError="true" /> <UserShadowStack UserShadowStack="true" UserShadowStackStrictMode="false" AuditUserShadowStack="false" /> </AppConfig> <AppConfig Executable="msfeedssync.exe"> <ASLR ForceRelocateImages="true" RequireInfo="false" /> </AppConfig> <AppConfig Executable="mshta.exe"> <ASLR ForceRelocateImages="true" RequireInfo="false" /> </AppConfig> <AppConfig Executable="ngen.exe"> <ExtensionPoints DisableExtensionPoints="true" /> </AppConfig> <AppConfig Executable="ngentask.exe"> <ExtensionPoints DisableExtensionPoints="true" /> </AppConfig> <AppConfig Executable="PresentationHost.exe"> <DEP Enable="true" EmulateAtlThunks="false" /> <ASLR ForceRelocateImages="true" RequireInfo="false" BottomUp="true" HighEntropy="true" /> <SEHOP Enable="true" TelemetryOnly="false" /> <Heap TerminateOnError="true" /> </AppConfig> <AppConfig Executable="PrintDialog.exe"> <ExtensionPoints DisableExtensionPoints="true" /> </AppConfig> <AppConfig Executable="runtimebroker.exe"> <ExtensionPoints DisableExtensionPoints="true" /> </AppConfig> <AppConfig Executable="SystemSettings.exe"> <ExtensionPoints DisableExtensionPoints="true" /> </AppConfig> <AppConfig Executable="C:\Windows\System32\vmcompute.exe"> <ControlFlowGuard Enable="true" SuppressExports="true" StrictControlFlowGuard="true" /> </AppConfig> <AppConfig Executable="C:\Windows\System32\vmwp.exe"> <ControlFlowGuard Enable="true" SuppressExports="true" StrictControlFlowGuard="true" /> </AppConfig> </MitigationPolicy> [/CODE][/SPOILER] [/QUOTE]
