Add tweak to block Logitech Download Assistant auto-install - #5034
Conversation
Mirrors the WPFTweaksRazerBlock folder-deny approach: clear C:\Program Files\LogiDownloadAssistant, recreate it empty, and deny Everyone write access so the Windows Update software-component package cannot re-deliver the payload. UndoScript removes the deny ACE. Unlike the Razer tweak, no global SearchOrderConfig/DisableCoInstallers registry changes: those alter driver search system-wide and do not stop software-component packages. Fixes ChrisTitusTech#5029

On non-English Windows installations, the built-in Everyone identity has a localized account name, so icacls can fail to resolve this English string and leave the directory writable. Because a nonzero native exit code does not throw here, Invoke-WinUtilScript will still report the tweak as completed. Use the locale-independent *S-1-1-0 form for both the deny and undo commands; Microsoft's icacls syntax documents prefixing numeric SIDs with *.

If LogiDownloadAssistant already has an explicit deny ACE for Everyone, /remove:d removes every deny ACE for that identity rather than only the (W) entry added by this tweak. Undoing the tweak can therefore erase a pre-existing security restriction; capture and restore the original ACL, or otherwise remove only the permission introduced here. Microsoft's icacls documentation defines /remove:d as removing all occurrences of denied rights for the SID.

Keeping /remove:d as-is, mirroring the merged WPFTweaksRazerBlock pattern: the only plausible pre-existing explicit Everyone deny on this specific folder is a manually applied version of the same block, which undo should also remove. Capturing and restoring the original ACL would require persisted state the tweak schema doesn't provide. The other findings are addressed in 9c253df.

to check $LASTEXITCODE immediately afterward and throw when it is non-zero,

success.

- Use the locale-independent *S-1-1-0 SID instead of the English "Everyone" name, which fails to resolve on non-English Windows. - Resolve the 64-bit Program Files directory via ProgramW6432 with a ProgramFiles fallback, so a 32-bit host cannot target the x86 folder. - Throw when icacls exits non-zero so Invoke-WinUtilScript logs the failure instead of reporting the tweak as completed. - Skip the undo icacls call when the folder no longer exists.

When icacls returns nonzero—for example because the directory ACL cannot be modified—this new throw still does not make the tweak fail: Invoke-WinUtilScript.ps1:32-49 catches the resulting runtime exception without rethrowing or returning failure, after which Invoke-WinUtilTweaks.ps1:84 unconditionally logs that the tweak completed. Fresh evidence in the hardened version is that the newly added exit-code check is therefore swallowed by the existing wrapper, so callers can still treat an unapplied block as successful; propagate a failure result so completion is not reported.

This is the standard execution model across all WinUtil tweaks. Invoke-WinUtilScript catches runtime exceptions so errors are logged without crashing the runner or aborting other queued tweaks. Propagating tweak failure status to Invoke-WinUtilTweaks would require changes to the core execution engine across the entire codebase, which is out of scope. You can safely disregard this!

Ran all test cases locally (all pass), and my own end-to-end test in a VM. Good work!

WPFTweaksLogiBlock, a CAUTION-category tweak that stops Windows Update from re-delivering the Logi Download Assistant alongside Logitech device drivers.It mirrors the
WPFTweaksRazerBlockfolder-deny approach:logi_download_assistantprocess if present.C:\Program Files\LogiDownloadAssistant(or pre-creates it empty when not installed).Everyone:(W)on the folder via icacls so the software-component driver package cannot write the payload back.UndoScriptremoves the deny ACE, restoring normal behavior.Deliberately narrower than the Razer tweak: no global
SearchOrderConfig/DisableCoInstallersregistry changes, since those alter driver search system-wide and do not stop software-component packages anyway. Approach was outlined in the issue before implementation.Verification:
.\Compile.ps1succeeds; full Pester suite passes 581/581 on currentmainplus this change; the icacls deny/undo cycle was functionally tested against a sandbox folder (write blocked after invoke, restored after undo). Not yet soak-tested against a real Logitech driver update cycle.Issue related to PR
