Windows Update
Pause or restore automatic updates with two big buttons—no Control Panel digging.
What you can do
Stop auto update
Fully stops download, install, and background schedules—including related services and policies—not just a short pause.
Restore auto update
Turn automatic updates back on when you are ready.
Use cases
- Avoid surprise reboots while editing or streaming.
- Finish setup after a fresh install before enabling updates.
- Keep a test machine stable while evaluating software.
Without this app
Typical manual steps—screens may differ by Windows version
- [Short term only] Settings → Windows Update → Pause updates for a few weeks (it turns back on automatically—not a permanent off).
- [Policy—Pro/Enterprise] gpedit.msc → Computer Configuration → Administrative Templates → Windows Components → Windows Update → Configure Automatic Updates → Disabled; optionally Remove access to use all Windows Update features → Enabled.
- [Services—do several] services.msc as admin—stop and set Disabled: Windows Update (wuauserv), Update Orchestrator Service (UsoSvc), Windows Update Medic Service (WaasMedicSvc); optionally Background Intelligent Transfer Service (BITS).
- [Registry] regedit → HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU (create keys if needed)—DWORD NoAutoUpdate = 1; AUOptions = 1 (notify only, no download).
- [Scheduled tasks] Task Scheduler → Task Scheduler Library → Microsoft → Windows → WindowsUpdate—disable the update-related tasks.
- [Delivery Optimization] Settings → Windows Update → Advanced options → Delivery Optimization—turn off downloads from other PCs.
- Note: disabling only one service may be undone by Medic Service or scheduled tasks; a full shutdown like this app needs policy/registry/services/tasks together.
- [Restore] Reverse the steps: re-enable tasks and services, remove or revert registry/policy, cancel pause in Windows Update, then check for updates manually.

Antivirus
Step-by-step guidance for Tamper Protection and real-time scanning, then one-click disable or restore.
What you can do
Open Windows Security
Jump to the built-in security app to turn off tamper and real-time protection.
Temporarily disable antivirus
After the guided steps, one click turns off all Defender toggles and background services so installs are not blocked.
Enable antivirus protection
Restore protection and scanning after setup is done.
Use cases
- Install tools that Defender keeps blocking.
- On-site repair with a safe way to turn protection back on.
- Reduce risk of leaving antivirus off by accident.
Without this app
Typical manual steps—screens may differ by Windows version
- Open Windows Security → Virus & threat protection → Manage settings.
- Turn off Tamper Protection first (confirm when prompted; other toggles may stay locked until you do).
- On the same page, turn off every protection toggle: Real-time protection, Cloud-delivered protection, Automatic sample submission, and similar items (names vary by Windows version).
- Those toggles alone may not stop background scans. For a full shutdown like this app: run services.msc as admin, stop and set to Disabled: Microsoft Defender Antivirus Service (WinDefend), Microsoft Defender Antivirus Network Inspection Service (WdNisSvc), and on Windows 11 Microsoft Defender Core Service.
- On Pro/Enterprise, you can also use Group Policy: Computer Configuration → Administrative Templates → Windows Components → Microsoft Defender Antivirus → Turn off Microsoft Defender Antivirus → Enabled (Home editions usually skip this).
- After installing your software, restore in reverse: set services back to Automatic and start them, then re-enable all toggles and Tamper Protection in Windows Security.

Network & Cloud
See whether OneDrive and sharing are on or off, then toggle them in one click.
What you can do
Close OneDrive
Unlink, uninstall, and stop background/startup so Windows Update is less likely to reinstall it automatically.
Open OneDrive
Bring OneDrive back when you need backup or sync.
Use cases
- Turn off OneDrive you never use.
- Check sharing before moving files on the LAN.
- Free RAM/CPU for editing or gaming.
Without this app
Typical manual steps—screens may differ by Windows version
- [Full OneDrive shutdown] Click the cloud icon in the taskbar → Settings → Unlink this PC or sign out, and turn off Start OneDrive when I sign in to Windows.
- Uninstall: Settings → Apps → Installed apps → Microsoft OneDrive → Uninstall. (Or run %localappdata%\Microsoft\OneDrive\OneDriveSetup.exe /uninstall)
- Open Task Manager → Startup and make sure Microsoft OneDrive is Disabled.
- Quit or uninstall alone may not stop Windows Update from bringing it back. For a full shutdown like this app: on Pro/Enterprise, use Group Policy → Computer Configuration → Administrative Templates → Windows Components → OneDrive → Prevent the usage of OneDrive for file storage → Enabled.
- On Home editions without Group Policy: run regedit as admin, create DWORD DisableFileSyncNG = 1 under HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\OneDrive (create the keys if missing).
- Restart when done; updates are less likely to reinstall OneDrive or sync in the background.
- To restore: remove the policy/registry value, reinstall OneDrive, and sign in again.
- [Network sharing] Settings → Network & internet → Advanced network settings → Advanced sharing settings → turn File and printer sharing and Network discovery on or off for your profile.

What you can do

Add user
Create a local account with optional password.
Cancel password expiry
Stop Windows from forcing periodic password changes.
Use cases
- Set up accounts for colleagues on a shared PC.

Without this app
Typical manual steps—screens may differ by Windows version
- Add a local account: Settings → Accounts → Other users → Add account → I don’t have this person’s sign-in information → Add a user without a Microsoft account.
- Remove: Settings → Accounts → Other users → select the account → Remove.
- Password never expires: open Command Prompt as admin and run: net user USERNAME /expires:never

Repair tools
One-click fixes for common errors—follow on-screen prompts and keep the repair window open until finished.
What you can do
Fix shared folder connection
Adjusts discovery, firewall, registry, and services so Windows 10 and 11 can see and open shared folders.
Repair Windows system files
Scan and repair corrupted OS files; may take several minutes.
Use cases
- Cannot see shared folders on the office LAN.
- Odd crashes—try a basic system file repair first.
- DIY troubleshooting before calling IT.
Without this app
Typical manual steps—screens may differ by Windows version
- [Shared folders—basics] Same network, Private profile; enable Network discovery and File and printer sharing; allow sharing in Windows Firewall.
- Workgroup without passwords: under All networks, turn off Password protected sharing—or sign in with the same local username/password on both PCs.
- For older gear, enable SMB 1.0: Control Panel → Programs → Turn Windows features on or off → SMB 1.0/CIFS File Sharing Support (Win10/11 often still needs the registry steps below).
- [Registry—both PCs] Run regedit as admin → HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters: add DWORD AllowInsecureGuestAuth = 1 and RequireSecuritySignature = 0.
- [Registry—host PC] HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters: add DWORD RequireSecuritySignature = 0 and EnableSecuritySignature = 0 if missing.
- [Registry—interop] HKLM\SYSTEM\CurrentControlSet\Control\Lsa: set LimitBlankPasswordUse to 0 only if you need blank-password shares (less secure). Restart, then test \\COMPUTERNAME\ShareName.
- Start these services (services.msc): Function Discovery Provider Host, Function Discovery Resource Publication, SSDP Discovery, UPnP Device Host.
- [Repair system files] Open Command Prompt as admin, run sfc /scannow, and wait until the scan finishes (can take a long time).
