Quick Assist is free, and on Windows 11 it is already on your PC. Press Ctrl + Windows logo key + Q and it opens. If nothing happens, the Microsoft Store reinstalls it in one click, and the package is 4.8 MB.
Microsoft distributes it through the Microsoft Store alone, under product ID 9P7BP5VNWKX5. There is no .exe, no offline installer, and no public Mac build outside a Microsoft Support case.
This guide covers the official Store listing, the winget command, the install steps, the network endpoints an admin has to open, and fixes for the WebView2 errors.
Which Quick Assist download do you need?
Match your PC to a row. Most rows need no download, because Windows already carries the app.
| Your machine | What to get | Download size |
|---|---|---|
| Windows 11, any supported version | Nothing. Press Ctrl + Windows logo key + Q | 0 |
| Windows 10 version 2004 (build 19041) or later | Nothing, unless someone removed it | 0 |
| Windows Search finds no Quick Assist | Quick Assist in the Microsoft Store | 4.8 MB |
| Windows 10 older than version 2004 | Install Windows updates first, then the Store app | 4.8 MB |
| A Mac | Only through an open Microsoft Support case | Not published |
| A work PC with the Store blocked | Ask IT to deploy it as a Store app in Intune | 4.8 MB |
Download Quick Assist from the official Microsoft source
Microsoft ships one package, from one storefront, for both sides of a session.
- Quick Assist in the Microsoft Store, product 9P7BP5VNWKX5 — 4.8 MB · publisher Microsoft Corp., free, rated 3.7 from 6,037 ratings
- Solve PC problems remotely using Quick Assist — Microsoft’s own instructions for both sides of a session
- Use Quick Assist to help users — the admin reference, with the endpoint list and the uninstall command
The Store delivers an AppxBundle signed by Microsoft. Any site offering a Quick Assist setup file is repackaging that bundle, and Microsoft’s own guidance is to get apps from official stores.
How to install Quick Assist on Windows 11 and 10
The install takes under a minute on a normal connection. Step 1 saves you the rest of the list.
- Press Ctrl + Windows logo key + Q. If the app opens, it is installed and you can stop here.
- Select Start, then All apps, then Microsoft Store.
- Type Quick Assist in the Store search box and press Enter.
- Select the result published by Microsoft Corp., under product ID 9P7BP5VNWKX5.
- Select Get. The button reads Install if the app was on this PC before.
- Give permission when Windows asks, then wait for the button to change to Open.
- On Windows 10, let the app fetch Microsoft Edge WebView2 on first launch. Windows 11 already has it.
- Sign in with a Microsoft account only if you are the one helping. The person sharing their screen never signs in.
Install Quick Assist with winget or push it out with Intune
The Store package is the only source, so both routes pull the same 4.8 MB bundle.
- Right-click Start and select Terminal (Admin).
- Run winget install 9P7BP5VNWKX5 –source msstore and accept the Store terms when prompted.
- Confirm the result with Get-AppxPackage -Name MicrosoftCorporationII.QuickAssist , which prints the version and install path.
- For a fleet, open the Intune admin center and add it as a Microsoft Store app (new).
- Search the Intune app picker for Quick Assist and pick the entry published by Microsoft Corp.
- Assign it to a device group, then let Intune install it on the next check-in.
How to verify the Quick Assist on your PC is the real one
Store packages carry a signature Windows checks for you, and one command reads it back.
- Right-click Start and select Terminal.
- Run Get-AppxPackage -Name MicrosoftCorporationII.QuickAssist | Format-List Name, Version, Publisher, SignatureKind .
- Check that SignatureKind reads Store . Anything else means the package did not come from Microsoft.
- Check that Publisher reads CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US .
- Check that PackageFamilyName reads MicrosoftCorporationII.QuickAssist_8wekyb3d8bbwe .
- Open the Store listing and confirm the product ID on screen is 9P7BP5VNWKX5.
Which Quick Assist download do you need for your Mac?
There is a macOS build, and Microsoft gates it behind a support case rather than a public page.
| Your situation | What Microsoft offers | How you get it |
|---|---|---|
| A Microsoft product on your Mac is failing | The macOS app, installed during the case | The support agent walks you through the download |
| You want to help a Windows user from a Mac | No public Mac build for that | Help from a Windows PC instead |
| You want the browser version | The web app is limited to verified support agents | Not available to the public |
Microsoft states plainly that the macOS app is not available outside Microsoft Support interactions. A Mac user working outside a case needs a different tool, and the table below names four.
Is Quick Assist free?
Quick Assist is free, with no paid tier and no trial. The Microsoft Store lists it at $0.00 with no in-app purchases, and the Windows licence covers it. Any page selling a Quick Assist key, licence or premium installer is not Microsoft.
The cost of this app is never money. Tech support scammers ask people to run it and then hand over control, so only accept a session you started yourself. Microsoft’s page on tech support scams covers the pattern.
How to check your Quick Assist version and update it
Store apps update themselves, and version 2.0.61.0 is the current build.
- Open Settings, then Apps, then Installed apps.
- Type Quick Assist in the search box and read the version next to the app.
- For a faster read, run Get-AppxPackage -Name MicrosoftCorporationII.QuickAssist | Select Version in Terminal.
- To force an update, open Microsoft Store, select Library, then Get updates.
- Restart the app after an update so the new WebView2 content loads.
Check the Quick Assist system requirements
The hardware bar is low. The real requirements are a current Windows build, the Edge WebView2 control, and outbound port 443.
| Field | Value |
|---|---|
| Software | Quick Assist |
| Developer | Microsoft Corp. |
| Latest version | 2.0.61.0 |
| Store product ID | 9P7BP5VNWKX5 |
| Price | Free |
| Supported OS | Windows 11, and Windows 10 version 2004 (build 19041) or later |
| Architecture | x64, x86 and ARM64 in one bundle |
| Download size | 4.8 MB for the bundle covering all three architectures |
| Installed size | 2.7 MB measured for the x64 package |
| Extra component | Microsoft Edge WebView2, built into Windows 11 |
| Network | Outbound port 443 to Microsoft’s Remote Assistance Service |
| Sign-in | Microsoft account or Microsoft Entra ID for the helper only |
| Offline installer | No |
| Mac version | Through Microsoft Support cases only |

Which network endpoints Quick Assist needs open
On a managed network the app installs and then fails to connect. These hosts are the reason, and all of them run over port 443.
| Endpoint | What it carries |
|---|---|
| *.support.services.microsoft.com | The primary endpoint for the session itself |
| *.live.com | Sign-in with a Microsoft account |
| login.microsoftonline.com and aadcdn.msauth.net | Sign-in with Microsoft Entra ID |
| remoteassistanceprodacs.communication.azure.com | Azure Communication Services for chat and connection |
| .trouter.skype.com, edge.skype.com and .cc.skype.com | Chat and the link between the two PCs |
| .flightproxy.skype.com and .registrar.skype.com | Azure Communication Services signalling |
| turn.azure.com | Media relay when a direct path is unavailable |
| .monitor.azure.com and .events.data.microsoft.com | Telemetry, diagnostics and remote service startup |
Blocking the first entry is also the documented way to switch the app off across an organisation. That block stops Intune Remote Help too, since both use the same service.
Fix Quick Assist not installing or not opening on Windows 11 and 10
Almost every failure traces back to the Edge WebView2 control, the Store, or a blocked endpoint.
Error 1001, 1002 or 1003 when the app starts
The Edge WebView2 control failed to initialise, load or install.
- Open Microsoft Edge, select the three dots, then Help and feedback, then About Microsoft Edge to update it.
- Close and reopen the app.
- If the error returns, install the Evergreen runtime from the Microsoft Edge WebView2 page.
- Restart the PC, then reinstall the app from the Store if the error survives.
Error 1004 on a work laptop
An Edge group policy is blocking the WebView2 update.
- Send the error number to your IT administrator.
- Ask them to review the Edge update policies applied to the device.
- Retry after the policy change reaches the PC.
The Store will not install it
Store access is restricted on managed devices.
- Check whether Microsoft Store opens at all on the PC.
- Ask IT to deploy the app through Intune instead.
- On a personal PC, sign in to the Store with a Microsoft account and retry Get.
The 6-digit code is rejected or the session never connects
The code expired, or the network blocks the service endpoints.
- Ask the helper to generate a fresh code. Each one is time limited.
- Give the endpoint table above to whoever runs the firewall.
- Test on a phone hotspot to confirm the network is the cause.
- Retry the session once the endpoints are reachable on port 443.
Windows Search finds nothing on Windows 10
The PC is older than version 2004, or the package was removed.
- Press Windows logo key + R, type winver , then press Enter to read the build number.
- Install pending updates if the build is below 19041.
- Install the app from the Microsoft Store.
How to uninstall Quick Assist
Windows allows the package to go. The app is not flagged as non-removable.
- Open Settings, then Apps, then Installed apps.
- Find Quick Assist, select the three dots next to it, then select Uninstall.
- Confirm with Uninstall in the prompt.
- To remove it for every account on the PC, run Get-AppxPackage -Name MicrosoftCorporationII.QuickAssist | Remove-AppxPackage -AllUsers in an elevated Terminal.
- Reinstall later from the Microsoft Store if you need it back.
Across an organisation, blocking the Remote Assistance Service endpoint is the method Microsoft documents, because it stops sessions even on PCs that still have the app.
Which Quick Assist alternative should you use?
The app covers one scenario well: a one-off session where the other person is at their PC and can approve it. The gaps are unattended access, Mac-to-Windows help, and audit logs.
| Tool | Use it when | Where to get it |
|---|---|---|
| Intune Remote Help | Your organisation needs role-based access, session logs and Conditional Access | Microsoft Learn |
| Microsoft Remote Desktop | You are connecting to your own PC, not helping someone at theirs | Techdows download guide |
| Chrome Remote Desktop | One side is on a Mac, Linux or ChromeOS machine | Techdows download guide |
| TeamViewer | You need unattended access, file transfer and cross-platform support | Techdows download guide |
| AnyDesk | You want a light client for quick sessions over slow links | Techdows download guide |
For one session between two Windows PCs, stay with Quick Assist. It is installed, free, and needs no account from the person sharing.
Frequently asked questions
Is Quick Assist free?
Yes. The Microsoft Store lists Quick Assist at $0.00 with no trial and no in-app purchases, and the Windows licence covers it. There is no premium edition and no key to buy.
What is the official Quick Assist download page?
The Microsoft Store listing at apps.microsoft.com/detail/9p7bp5vnwkx5, published by Microsoft Corp. under product ID 9P7BP5VNWKX5. Microsoft’s support and Learn pages both point there, and no other site distributes it.
Does Quick Assist work on Windows 11?
Yes, and it ships with Windows 11, so no download is needed. Press Ctrl + Windows logo key + Q to open it. Windows 10 needs version 2004, build 19041, or later.
How big is the Quick Assist download?
The Store bundle is 4.8 MB, and it covers x64, x86 and ARM64 in one package. Microsoft’s catalogue caps the install at 3.5 MB, and an x64 install measures about 2.7 MB on disk.
Is there a Quick Assist offline installer or .exe?
No. Microsoft ships it only as a Microsoft Store package, so there is no standalone setup file to copy between PCs. Admins deploy it through Intune as a Microsoft Store app instead.
Can you download Quick Assist for Mac?
Only inside a Microsoft Support case. A support agent guides the macOS install during the case, and Microsoft states the Mac app is not available outside those interactions. The web version is limited to verified support agents.
Does Quick Assist support 64-bit and ARM64 PCs?
Yes. The Store bundle contains x64, x86 and ARM64 builds, and Windows installs the one that matches the PC. Copilot+ PCs on Snapdragon run the ARM64 build natively.
Is Quick Assist safe to use?
The app itself is signed by Microsoft and sessions run over TLS 1.2. The risk is social: scammers ask people to start a session and then take control. Only accept a session you started yourself.
What is the latest Quick Assist version?
Version 2.0.61.0, published by Microsoft Corp. through the Microsoft Store. Store apps update themselves, so checking Library then Get updates in the Store is enough to stay current.
Why will Quick Assist not install or open?
Errors 1001 to 1004 all point at the Edge WebView2 control, which renders the app interface. Update Microsoft Edge, install the WebView2 runtime, then reopen the app. On managed PCs, Store restrictions block the install.
