Common causes
- Connecting to many different computers from one free installation, a pattern that looks more like a technician or support business than occasional help for family.
- Frequent, long, or regular sessions during working hours, which resemble ongoing professional work rather than the occasional personal use the free license covers.
- Using the free version for anything work-related, such as reaching your office PC, helping colleagues, or supporting customers, which counts as commercial use even when unpaid.
- Connecting to or from a computer that has been used with a TeamViewer business license, trial, or company deployment, which can associate the device with commercial use.
- Running TeamViewer on a server operating system or on a computer that is part of a managed business network, which detection may treat as a business environment.
- Several people sharing one installation or account to help others, which multiplies the number of connections and devices tied to a single free license.
- A false positive: TeamViewer does not publish exactly how its detection works, so a genuine personal user who helps many relatives can occasionally be flagged.

Step-by-step fixes
Step 1
Read the message and note what it affects
Start by reading the TeamViewer warning closely rather than dismissing it. Depending on the version, it may say commercial use suspected or commercial use detected, and it may warn that sessions will be time-limited. Either wording means TeamViewer's system believes the free license is being used for business. Note which device shows the message, when it first appeared, and what happens to your sessions, such as disconnecting after a short time. Write down the TeamViewer ID of your computer, which is shown in the main TeamViewer window, and the IDs of the computers you usually connect to. If the warning includes a link to TeamViewer's support information, keep it. You will need these details for a review request, and they also help you judge whether the flag is fair.
Step 2
Check honestly whether your use is commercial
TeamViewer's free license covers private use, such as accessing your own home computer or helping friends and family without payment. It does not cover work, and the line is stricter than many people expect. Connecting to your office computer from home, helping coworkers, supporting a relative's business, charging for computer help, and using TeamViewer on behalf of any company or organization all count as commercial use, even if they only happen occasionally. Read the license terms on TeamViewer's website if you are unsure. If any part of your use is work-related, a review request is not the right route and is unlikely to succeed, so skip ahead to buying a license or choosing another tool. If your use is genuinely personal, continue with the next steps.
Step 3
Separate work devices and old company setups
A flag can come from the other side of the connection. If you connect to a computer that belongs to an employer, or one that has run a company's TeamViewer license or custom module, sessions with it can look commercial even when your intent is personal. Keep work and personal use apart: use your employer's licensed TeamViewer or approved remote access tool for work devices, and your free installation only for personal ones. If a computer you own was previously managed through an employer's TeamViewer account, ask that organization's IT team to remove it from their management console. Also confirm you downloaded TeamViewer from teamviewer.com rather than a third-party site, because modified or bundled installers are both a security risk and a licensing problem.

Step 4
Submit TeamViewer's official reset request
If you are a genuine personal user, the legitimate fix is TeamViewer's own review process. On teamviewer.com, search the support section for commercial use suspected, or follow the link in the warning, and open the personal-use reset request form. You will typically be asked for the TeamViewer IDs of the affected devices, your name and email address, and confirmation that you use TeamViewer only privately. Include every ID that shows the warning, and describe your use briefly and truthfully, for example helping your parents and accessing your own laptop. Submit the form once and keep any confirmation email. TeamViewer reviews requests individually, so a reset is not guaranteed, and it may take several days to hear back.
Step 5
Use a stopgap tool while the review is pending
While TeamViewer reviews your request, you may still need to help someone or reach your own computer. Rather than repeatedly reconnecting through time-limited sessions, use a different free tool for now. To help someone on Windows 10 or 11, open Quick Assist by searching for it from the Start menu, sign in as the helper, and share the security code it gives you. For your own computers, Chrome Remote Desktop is free with no paid tier: set up each computer at remotedesktop.google.com and protect it with a PIN. Avoid submitting multiple review requests or creating new accounts to get around the flag, since that can complicate the review and may breach the terms. Once TeamViewer confirms the reset, restart the app on each device and test a session.
Step 6
Buy a TeamViewer license if your use is commercial
If your use is work-related, or the review is declined, a paid license is the correct fix. TeamViewer's plans differ mainly by the number of licensed users, concurrent sessions, and managed devices, so match the plan to what you actually do: a single-user plan for reaching your own work computers, and a business tier if you support other people or need several technicians. Check whether a trial is available so you can confirm the plan works with your devices first. After purchase, sign in to TeamViewer on your computer with the account that holds the license, and confirm the license shows in the app. Plans are subscriptions that renew automatically, so note the renewal date and how far in advance you must cancel.
Step 7
Switch to a tool whose license fits your use
If TeamViewer's pricing or free-use limits do not suit you, move to a tool that matches how you actually work. For personal use, Chrome Remote Desktop is free with no paid tier, and RustDesk is open source and free to use, with the option of hosting your own server. AnyDesk is another popular choice, but its free version is also limited to personal use, so it does not solve a commercial-use problem. For work, look at tools built for business, such as Splashtop for remote access and IT support, or the paid tiers of AnyDesk and RustDesk. Try the replacement on the devices you support most, then uninstall TeamViewer from Settings > Apps > Installed apps (Apps & features on Windows 10) once you no longer need it.
How to prevent it
- Keep your free TeamViewer installation strictly for personal use, and use a licensed or employer-approved tool for anything work-related.
- Do not use a personal installation to reach a work computer, even occasionally.
- Keep a simple list of the TeamViewer IDs you connect to so a review request is quick if you are ever flagged.
- Download TeamViewer only from teamviewer.com and never run unofficial reset or patch tools.
- If you help many people regularly, choose a tool whose license allows it rather than relying on a personal free tier.
Tools that can help
If your use is genuinely personal, TeamViewer's free review process is the right first step and costs nothing. If your use is commercial, or you want to avoid personal-use limits altogether, a paid plan or a different remote access tool is the cleaner long-term answer.

FAQ
What does commercial use suspected mean in TeamViewer?
It means TeamViewer's automatic detection believes the free version, which is licensed only for personal use, is being used for business purposes. The decision is based on usage patterns rather than a person reviewing your activity, so heavy personal use can trigger it. The warning can be followed by restrictions such as time-limited sessions until the flag is reviewed or a license is purchased.
Why do my free TeamViewer sessions keep timing out?
If sessions on the free version end after a short time and TeamViewer has shown a commercial-use warning, your device or the one you connect to has most likely been flagged. The time limit is how TeamViewer restricts flagged free installations. A genuine personal user can request a review through TeamViewer's official process, while commercial users need a paid license or a different tool.
How long does a TeamViewer commercial use review take?
TeamViewer does not guarantee a turnaround time, and a review can take several days. Submitting the form once, with accurate TeamViewer IDs and a clear, honest description of your personal use, gives it the best chance of being processed smoothly. Repeated submissions do not speed things up. Use a free tool such as Quick Assist or Chrome Remote Desktop in the meantime if you need remote access.
Can I clear the flag with a reset tool or by reinstalling?
You should not try. ID-reset tools and similar workarounds are designed to evade license detection, which breaches TeamViewer's terms, and they often come from untrustworthy download sites that bundle malware. Reinstalling is not a supported way to clear the flag either. If you have already run an unofficial tool, scan your PC for malware, then use the official review process or a properly licensed tool.
Is helping family and friends considered commercial use?
Generally no. Helping relatives and friends with their personal computers, without payment, is the kind of private use the free version is meant for. It becomes commercial if you are paid, if the computer is used for someone's business, or if you are helping colleagues or customers. Helping a large number of people regularly can also trigger detection, even when your intent is personal.
What is the best free alternative to TeamViewer for personal use?
Chrome Remote Desktop is the simplest free option for reaching your own computers or helping someone with a one-time code, and it has no paid tier. RustDesk is a strong open-source choice if you want more features or your own server. For helping someone on Windows, Quick Assist is already included. AnyDesk is popular too, but its free version is also limited to personal use.
