A small collection of Windows support scripts for Active Directory, Acrobat/Reader, Microsoft Teams, OneDrive, classic Outlook and optional Windows apps. All eight CMD entry points default to preview only. No script downloads or executes remote code.
Read this before using the scripts on a user's PC.
/applychanges the current machine or account, sometimes irreversibly. Test in an isolated VM, review the proposed targets, keep backups and verify the affected account. The repository is MIT-licensed and provided without warranty.
Open a terminal in the repository and run a script without arguments, or explicitly pass /preview:
ms-teams\full-clear-teams-cache.cmd /previewReview its output. To carry out the operation, use /apply:
ms-teams\full-clear-teams-cache.cmd /applyDestructive or machine-wide helpers also require a typed confirmation. /help prints usage. A successful preview does not establish that applying the change will succeed. Scripts return exit code 0 for success or a safe skip, 1 for an operational failure and 2 for invalid usage or a cancelled operation.
Account context matters: Run Teams, Outlook and per-user Appx tasks as the affected user. Starting them through an alternate administrator account changes the administrator's own profile/HKCU instead. Use an elevated terminal for machine-wide Adobe/OneDrive policy changes and Appx deprovisioning, preferably by elevating the intended account rather than switching accounts.
The PowerShell helpers use Windows PowerShell 5.1 and the built-in Windows utilities. CMD launchers set the execution policy only for their own PowerShell process; organization-enforced policies still apply. Inspect the local, trusted scripts before execution.
| Entry point | Preview / apply behavior | Scope and recovery |
|---|---|---|
| Launch AD console | /apply securely prompts for a domain, account and password, then starts dsa.msc with alternate credentials. |
Requires RSAT Active Directory tools and a simple DNS/NetBIOS domain and sAMAccountName. No password is stored. Closing the console undoes the action. |
| Disable Adobe JavaScript | Detects supported Reader/Acrobat DC installations before setting bDisableJavaScript=1 and bDisableTrustedFolders=1. |
Machine-wide Adobe policy. Existing target keys are exported to a timestamped REG backup in %TEMP% before modification. Review managed policies before restoring a backup. |
| Reset Teams login cache | Only clears the new Teams-specific cache after Teams is closed and you type RESET. |
Does not delete OneAuth, TokenBroker, IdentityCache or AAD BrokerPlugin. It cannot guarantee sign-out with Windows SSO; use Teams' own Sign out if account separation is required. |
| Reset full Teams caches | Clears new Teams' cache and known classic Teams cache subfolders after confirmation. | Preserves shared M365 identity stores and classic diagnostic logs outside the listed caches. Some personalization may be lost; restart Teams. |
| Disable/remove OneDrive | After confirmation, sets the documented DisableFileSyncNGSC=1 machine policy and invokes an available OneDrive uninstaller. |
Never deletes %UserProfile%\OneDrive or its contents. Verify sync and backup status manually before applying. An existing policy key is exported to %TEMP%. Reverting requires changing the policy, and reinstalling OneDrive if removed. |
| Classic Outlook FORMS2 workaround | Only creates the quoted %LOCALAPPDATA%\Microsoft\FORMS2 folder when missing and Outlook is closed. |
For the specific June 2025 classic Outlook forms-library crash. Microsoft has fixed the issue in subsequent builds: update Office first. |
| Hide New Outlook toggle | /apply sets the current user's HideNewOutlookToggle=1; /restore removes the local value after confirmation. |
Only affects the classic Outlook toggle, not installation of the new app. Do not override organization-managed settings. |
| Remove selected Appx apps | Shows exact package names first; /apply requires admin rights and typed REMOVE. |
Only removes matching installed apps from the current user and deprovisions matching packages for future accounts. Does not affect every existing user and does not permanently block Store/Windows reinstallation. |
Microsoft does not recommend cache deletion as a general fix for missing chats, channels or notifications: it can remove diagnostics that support needs. Use the cache scripts only for a targeted local-client problem after checking network, service and account status. Official procedure: Clear the Teams client cache.
DisableFileSyncNGSC is the Windows policy that prevents OneDrive sync; it affects the machine and may be re-applied or controlled by Group Policy/MDM. See Microsoft's OneDrive policy guidance. Do not use the uninstaller until you have independently checked the user's sync queue and backups. The script cannot prove that cloud files are fully synchronized.
The script supports detected DC registry footprints for Reader/Acrobat and their 32-/64-bit policy paths. If installation detection fails, it makes no changes. Confirm your Adobe package's registry layout and deploy managed policy through GPO/MDM where appropriate. The keys disable JavaScript and trusted folders; they do not promise to disable every other trust mechanism. See Adobe's enterprise registry guidance.
Microsoft documents the FORMS2 workaround for a fixed June 2025 crash. Check the known-issue article and installed build before applying it. The New Outlook toggle setting does not remove the new Outlook application.
GitHub Actions parses every PowerShell helper, runs static safety tests and smoke-tests every CMD launcher in /preview mode on Windows. The workflow intentionally never calls /apply or /restore. Follow the VM test plan for manual changes that cannot safely be exercised in CI.
- Non-destructive Office licensing diagnostics and report export
- Network, print spooler and system information collection (preview-first)
- A targeted Outlook profile diagnostic, without deleting a user's profile
