Get-NTFSEffectiveAccess -ServerName with a computer that can't be
resolved or reached returned no access, while it warned that it had
calculated the result on this computer. In that case,
AuthzInitializeRemoteResourceManager fails with RPC_S_SERVER_UNAVAILABLE
(1722); the code fell back to the local authorization manager only for
EPT_S_NOT_REGISTERED (1753), and GetEffectiveAccess swallowed the
exception. It now falls back for 1722 as well, as the cmdlet page
describes. The live tests in a lab found it; the new test in
Access.Tests.ps1 reproduces it on any computer.

Add Tests\Lab, which runs the module against a Windows file server with
domain accounts in an AutomatedLab lab: #34 over SMB, the audit cmdlets
over SMB, Get-NTFSEffectiveAccess with domain and file server groups,
Get-NTFSOrphanedAccess with a deleted domain account, long paths on a
share, and #108. Invoke-NTFSSecurityLabTest.ps1 prepares the lab and
runs the tests per module version and PowerShell edition; without a
lab, every live test skips. CI excludes the folder.

- activeContext: the maintainer decided to run live tests of 5.0.0-rc4 in
a lab before 5.0.0, on another workstation with his lab script; the four
cases that no local test covers (#34 and the audit cmdlets over SMB,
effective access with domain accounts and -ServerName, orphaned entries
of a deleted domain account), against rc2 as the baseline and rc4; the
tester feedback on IBM ESS expected in #34.
- progress: 5.0.0 waits for the live tests and the #34 feedback.

- progress and activeContext: 5.0.0-rc4 published from 01d9264; #41,
#108, #109, and #111 closed as completed, #90 and #107 as not planned;
the deferred review findings are listed in #113; 5.0.0 is next.
- techContext: the label rc4 and the Gallery versions; AlphaFS reaches the
device object for a drive or volume root through DirectoryInfo and the
root folder through the path methods; stale lines shortened.

- Read the root folder for a volume name such as \\?\Volume{GUID}\ too,
like for a drive letter, and accept only the letters A to Z as a drive
- Report a security descriptor without the audit entries without naming a
missing Security privilege as the cause, which may not be the reason
- Skip the audit tests that change a descriptor from
Get-NTFSSecurityDescriptor in a session without the Security privilege
- Assert the absence of the old hint in the Get-NTFSEffectiveAccess test
- Narrow the drive-root note of Get-NTFSAccess to the security cmdlets

Set the prerelease label rc4, and add 5.0.0-rc3 to the versions that the
PowerShell Gallery already has.

- #41: for the root of a drive, the cmdlets read and changed the security
descriptor of the drive, a device object. FileSystemSecurity2 now routes
drive roots through the path-based AlphaFS methods, which keep the
trailing backslash; the removal and inheritance helpers use it too.
- #109: Add-, Remove-, and Clear-NTFSAudit report a security descriptor
without the audit entries like Get-NTFSAudit, through one helper, and
Get-NTFSEffectiveAccess names the cause that Windows reported instead
of a missing Security privilege.
- #108: Copy-Item2 and Move-Item2 check the destination only for an
operation that runs; with -WhatIf, a verbose message names the conflict.
- #111: Disable-Privileges skips the privileges that the token doesn't
hold, the privilege messages are spelled right, and Get-FileHash2
declares the type name of its objects; 05-Releasing.md documents the
release metadata tests.
- rc3 review leftovers: Remove-NTFSAudit writes nothing for an item
without a SACL, the owner retry of Set-NTFSSecurityDescriptor restores
the previous owner in a finally block and keeps an owner that the
descriptor sets, and FileSystemSecurity2.Write with another item writes
only the sections that were read.
Each fix has a test that failed first, in Windows PowerShell 5.1 and
PowerShell 7; writing a drive root was checked once on a temporary VHD.

- progress and activeContext: 5.0.0-rc3 published from 914e8da; #34
reopened for a tester, #67 closed as not planned; 5.0.0 is next.
- Decision 19: the cmdlets write only the sections that they change.
Decision 18: the Gallery description announces the archive, and the
module writes no warning on import.
- techContext: the label rc3 and the Gallery versions; commands for the
maintainer as code blocks at the end of the reply; no closing keywords

- Set-NTFSSecurityDescriptor -Verbose names the sections that it writes,
or says that it writes nothing for an unchanged descriptor; its page
says "since it was read or last written" (review F-02).
- The pages of Enable-NTFSAccessInheritance, Disable-NTFSAccessInheritance,
and Set-NTFSInheritance get the #34 note, like the other fixed cmdlets
(review F-06).
- Set-TestOwner throws its own error when icacls fails, also when the

Written through its UNC path, the DACL of a share root can't re-inherit
from the parent folder on the server: Windows drops the inherited entries
of a DACL in the auto-inherit format and stores the others as explicit
copies. icacls and Set-Acl behave the same; a subfolder through the share
and the local path keep them (#67).

The access and audit cmdlets wrote the owner of an item back with the
entries they changed. For a DACL without the auto-inherit flag, Windows
returns the owner and the group even when only the DACL is read, and the
cmdlets wrote every section that the descriptor held. Without the Restore
privilege, or on a file server that refuses the owner, the write failed
with error 1307 (#34).
- Add-NTFSAccess, Clear-NTFSAccess, Add-NTFSAudit, and Clear-NTFSAudit
read only the DACL or the SACL. FileSystemSecurity2.Write(),
Remove-NTFSAccess, and Remove-NTFSAudit write only the sections they
read, which also fixes the access inheritance cmdlets.
- Read together with the SACL, the inherited entries of such a DACL lose
their inherited flag when the parent folder has no SACL, and the
cmdlets stored them as explicit copies. Get-NTFSSecurityDescriptor now
reads the DACL in a separate call.
- Set-NTFSSecurityDescriptor writes only the sections that changed since
they were read; an unchanged descriptor writes nothing (maintainer
decision of 2026-10-06).
- Clear-NTFSAudit writes nothing for an item without a SACL, and reports
an error without the Security privilege (maintainer decision).
The regression tests failed before and pass after the fix in Windows
PowerShell 5.1 and PowerShell 7, elevated and as a basic user.

The maintainer decided on 2026-10-06 to publish 5.0.0-rc3 before 5.0.0
and to archive NTFSSecurity in favor of WindowsAccessControl.
- Decision 18: the project will be archived; the notes in the README,
the docs home, and the changelog stay until then.
- activeContext: rc3 is the focus. #34 reproduces locally with rc2, on a
file owned by TrustedInstaller without the Restore privilege, so CI can
test the fix without a file server.
- progress: rc3, then 5.0.0, with the version steps of each.

The maintainer approved a label scheme on 2026-10-06, and it was applied
to the 42 issues triaged on 2026-10-05, with the new label Needs Info for

- Decision 17: the meaning of each label and the close reasons.
- activeContext and progress: the labels are applied; five issues wait
for their reporters.

5.0.0-rc2 is on the PowerShell Gallery and in the GitHub releases. The
PRs #99 to #106 were merged in order with merge commits, CI on master
passed, and the tag 5.0.0-rc2 on 7ddda8d published it on the third
attempt of the release run, after GitHub's Actions outage of 2026-10-05.
The open issues got their replies, 16 were closed, and the follow-up
issues #107 to #111 track the open Minor review findings.
- Decision 14: repository hardening is optional; the outdated "pending"
text is gone.
- Decision 15: merge stacked pull requests in order with merge commits.
- Decision 16: fix only reproducible bugs (the maintainer's decision D6).
- activeContext and progress: the CI fix 629f4e7, the copied inherited
entries behind #34, the issue state, and the next step (test rc2, then
5.0.0 or rc3).
- techContext: the current versions, the second workstation, and
one-line commands for the maintainer.

Enable-NTFSAuditInheritance, Disable-NTFSAuditInheritance, and
Set-NTFSInheritance -AuditInheritanceEnabled failed with "(5) Access is
denied" for a file or folder without a SACL, also elevated with the
Security privilege. The cmdlets read only the audit section and changed
the flag that disables or enables audit inheritance. AlphaFS writes that
flag only together with a SACL, so it wrote no section at all, which
Windows denies; the retry as owner repeated the same write. An empty SACL
is now added first, but only to a descriptor that was read with its SACL.
The elevated CI runs of #100 to #106 showed this through the test of an
omitted -AccessInheritanceEnabled. From #104 on, the test that keeps the
inherited entries of a security descriptor failed as well: elevated,
Get-NTFSSecurityDescriptor reads the SACL, and Windows then returns a DACL
that isn't in the auto-inherit format, such as that of a file in the temp
folder of the user, without its inherited flags. The test now reads the
access section only and checks that the descriptor has inherited entries.
Tests: five cases for items without audit entries, red with "Access is
denied" before the fix; the test that keeps the explicit audit entries now
checks the errors and the inheritance state of both calls; a test checks
that a descriptor read without its audit entries gets no SACL, which would
replace the audit entries of the item when it is written.

An empty Get-ChildItem2 -Attributes value, such as 0 or None in
PowerShell 7, matched every item and returned hidden items as well; it now
stops the cmdlet with AttributesEmpty, as Get-ChildItem rejects it. The page
says that the + and ! operators of Get-ChildItem aren't supported and that
-Recurse still enters hidden folders, and the changelog says that a call
with several attributes now returns more items. The type data test starts
Windows PowerShell, where the import failed, from both CI legs and checks
that LengthOnDisk is still there.

The types file added the alias Size of LengthOnDisk to System.IO.FileInfo.
Type data can't replace an existing member, so in Windows PowerShell the
import failed when another module had added a Size member first (#82).

Get-ChildItem2 -Attributes returned only the items that had all the listed
attributes, so -Attributes Hidden, ReadOnly returned nothing where
Get-ChildItem returns both kinds of items. It now returns the items that have
any of them (#5).
BREAKING CHANGE: to get only the items with all the listed attributes,
filter the result with Where-Object, as the cmdlet page shows.

The fix for #17 stopped adding Synchronize to an Allow rule with generic
rights, which bypassed the exact match of FileSystemSecurity.RemoveAccessRule:
-AccessRights GenericAll left a Synchronize-only entry behind when the entry
also had Synchronize. RemoveRule now does what FileSystemSecurity does,
without its validation: it removes a rule that matches an entry exactly as it
is, and otherwise without Synchronize. It covers every mask that .NET
rejects, not only the generic rights. The tests cover -RemoveSpecific, a
Deny entry, a partial generic mask, and that nothing else is removed.

FileSystemSecurity.RemoveAccessRule rebuilds a rule that doesn't match an
entry exactly and rejects generic rights then, so removing an entry with
GENERIC_ALL failed with "The value '269484032' is not valid". Windows keeps
generic rights in the inherit-only entries of folders. Such a rule is now
removed through ModifyAccessRule, without the added Synchronize right
(#17).

Nine cmdlets still read the PWD variable for the default location when
-Path was omitted, so #86 remained for that form; they now use
GetCurrentLocation. Copy-Item2 writes the object that CopyTo returns for the
copy instead of relying on AlphaFS to update the source object, and a test
covers a folder.

Mark the Set-NTFSInheritance change as breaking and warn that scripts that
used it to drop the inherited access entries now leave broader access in
place. Report any failure to create the hash algorithm as

The new FAQ page answers the questions that the issues ask again and again
and links the pages with the details. The Get-NTFSEffectiveAccess page said
that a security descriptor produces no result, and the Copy-Item2 page now

Windows PowerShell binds an object that is passed by position to a string
parameter through ToString, which returns only the name of a child item, so
the cmdlets looked for it in the current location. The path parameters now

A variable named PWD in the scope of the caller, such as a loop variable,
hid the automatic variable, and every cmdlet failed with a
NullReferenceException, also for an absolute path. The cmdlets now read
the current file system location from the session state, and only for a
relative path (#86).

The message overloads of BaseCmdletWithPrivControl hide the methods of
Cmdlet, so every message went through string.Format, also one without

-AccessInheritanceEnabled $false now copies the inherited access entries

Get-FileHash2 failed in PowerShell 7 for every algorithm, because the hash
method referenced RIPEMD160, which .NET Core and later lack. RIPEMD160 and
MACTripleDES are now created by name; requesting one where .NET lacks it
stops the cmdlet with an error that names the algorithm and points to
Windows PowerShell 5.1. MACTripleDES uses a random key, so its result
differs on every call; the value is deprecated, and the cmdlet warns when
it is used.
