About this tag
The ACL tag on WindowsForum.com covers access control list issues in Windows and enterprise environments. Discussions include a Galaxy Connect bug causing C: drive access denied on Windows 11, an MSMQ patch regression where security hardening removed write access for service accounts, and safe methods to view WindowsApps folders without altering ACLs. Other topics involve Redis Lua scripting ACL bypass vulnerabilities, OT network hygiene for Siemens RUGGEDCOM, and Modicon M340 file exposure risks. NetApp connector for Microsoft 365 Copilot also touches on preserving item-level security. Common themes are troubleshooting access denied errors, understanding NTFS permissions, and applying security patches that affect ACL behavior.
Microsoft and Samsung have confirmed that a buggy version of the Samsung Galaxy Connect application distributed through the Microsoft Store caused a subset of Samsung Galaxy Book 4 and desktop systems running Windows 11 to report the frightening error “C:\ is not accessible – Access denied,”...
Microsoft has quietly shipped an out‑of‑band update to undo a December security hardening that left Microsoft Message Queuing (MSMQ) unable to write its on‑disk message files on many enterprise systems, restoring queue functionality after a week of outages, confusing logs, and emergency...
Microsoft pushed an unscheduled out‑of‑band update after December’s Patch Tuesday to remediate a damaging regression in Microsoft Message Queuing (MSMQ) that prevented many applications and IIS‑hosted services from writing messages to disk. The failure was traced to a security hardening that...
Redis’ Lua scripting subsystem contained a subtle but consequential weakness that let a less‑privileged user inject code which could later execute with the privileges of a higher‑privileged Redis user — a bug tracked as CVE‑2022‑24735 and fixed in Redis 6.2.7 and 7.0.0. Background / Overview...
Microsoft Store apps live inside a heavily protected folder — C:\Program Files\WindowsApps — and while Windows intentionally hides and locks this location, there are safe, supported ways to view a single app’s installation folder, and riskier options for full access when absolutely necessary...
Siemens and U.S. cyber authorities have republished a focused advisory addressing two low‑severity but operationally meaningful vulnerabilities in SINEC OS that affect the RUGGEDCOM RST2428P (6GK6242‑6PA00); the immediate mitigation is straightforward (block discovery UDP ports) but the broader...
Schneider Electric has confirmed a security issue affecting the Modicon M340 family and two Ethernet communication modules — BMXNOE0100 and BMXNOE0110 — that can expose files or directories to external parties and, in some configurations, can prevent firmware updates or disrupt the embedded...
Microsoft 365 Copilot can now tap enterprise file shares without forcing a wholesale migration to the cloud: NetApp’s new connector brings on‑prem and cloud NetApp data into Copilot while preserving item‑level security, offering containerized deployment options, and promising high performance...
CVE-2025-50164 — Heap-based buffer overflow in Windows RRAS: what admins need to know now
TL;DR: Microsoft lists CVE-2025-50164 as a heap-based buffer‑overflow in the Windows Routing and Remote Access Service (RRAS) that can lead to remote code execution. Administrators should treat this as...
Microsoft has confirmed an elevation-of-privilege flaw in Azure File Sync that can allow an authenticated, local attacker to escalate privileges on systems running the service — a serious risk for hybrid infrastructures that bridge on‑premises Windows servers and Azure file storage. Public...
I want to understand if this pattern has been explored.
In an enterprise environment, if a service hosted on server A ("ssa") needs to interact with services on server B ("ssb") , it is required to create a "service account" that is configured to run ssa, with that service account then having...

The "Local Administrator Password Solution" (LAPS) provides management of local account passwords of domain joined computers. Passwords are stored in Active Directory (AD) and protected by ACL, so only eligible users can read it or request its reset.

Hi
In Windows7 SP1, I noticed that the ACLs of the root directory of a logical partition (D:) formatted NTFS are different from those of the root directory of the system partition (C:):
C:\Windows\system32>icacls c:\
c:\ BUILTIN\Administrators:(F)
BUILTIN\Administrators:(OI)(CI)(IO)(F)...

HI
I have Windows 7 SP1 and I should only move the users profiles (without the default profile) and the public folder in a NTFS logical partition.
I should modify the ACLs of the root directory (\) of the logical partition to still have a coherent and stable system or not? If so, how should I...
Fixes a problem in which a folder that is created under the root of system drive is missing ACLs, which may cause problems on the English version of Windows 7 Release Candidate 32-bit Ultimate.

Hi all
I just restarted my computer and for some reason it gets stuck on the logo screen. I restarted it a few times and nothing happened, so I ran the Startup Repair tool.
Here is the start of the log:

I've recently upgraded from Windows XP to Windows 7. The data disk, where all of
the user project folders are stored is separate from the system disk, and untouched
by the upgrade.
I am the owner and...

I attempted to run msconfig to uncheck some progs in my startup, like I did already many times before, always with no problems at all.
Then my Windows 7 Ultimate PC (Dell XPS M1530) crashed with a broken RAM (one of my two 2GB is defect, so I took it out and restarted with 2GB). All is fine...
