How to Reset TeamViewer ID

After installing TeamViewer and first connection to the network, program receives a unique identification number (ID). It allows you to perform a remote connection to your computer. If you are using a free version of TeamViewer to connect to different computers (commercial purposes), here is a high probability that your remote connections will be limited on the TeamViewer server to a value not exceeding five minutes, after which the connection will be terminated. In this case, the only way to unblock limitation is to reset the TeamViewer ID (or purchase a license 🙂 ).

You can see your TeamViewer ID on the main screen when running application.

TeamViewer ID is generated basing on several unique attributes of your computer:

  • MAC address of the network card
  • VolumeID of disk partition
  • Creation date of folder Program Files

Accordingly, in order to change the ID in the TeamViewer, you need to change these three values.

To reset the ID you need to perform a few steps.

First of all, Terminate TeamViewer process. Then you need to remove current ID from the registry.

  • For Windows x86, Teamviewer version [X], open regedit.exe, go to the branch HKLM\SOFTWARE\TeamViewer\Version[X] and delete DWORD value ClientID.
  • For Windows x64, delete value ClientID from HKLM\SOFTWARE\Wow6432Node\TeamViewer\Version[X]

To change the creation date of Program Files folder, you can use NirCMD utility. Download it and run the following command in a command prompt console:

nircmdc.exe setfilefoldertime "C:\Program Files" now now


To change MAC address of the network card, you can use special utilities or use the following instructions for manually edit MAC address in registry.

To get the current MAC address of your network card, open command prompt and execute following command:

Ipconfig /all


We are interested in two parameters:

  • Description (LAN card description) Intel(R) 82574L Gigabit Network Connection
  • Physical Address (MAC address) 00-50-56-9E-FC-CB

Then, open Registry Editor and go to branch HKLM\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}.

Each network component in this branch is indicated by four digits starting from 0000, 0001 and so on. You can find the right branch by browsing it and looking for DriverDesc option, where must be specified the description (name) of your network card, for example: Intel(R) 82574L Gigabit Network Connection.

Once the correct network card is found, add or modify REG_SZ key with name NetworkAddress, which determines MAC (hardware) address of the network card. It is enough to change a single digit in the current address, for example 0050560EFCCB.

So, MAC address of the network card is changed. Now you need to change VolumeID of system partition. VolumeID (or Volume Serial Number) is a unique identifier of a volume on hard drive, which is set during formatting.

Note. In some cases, TeamViewer is linked to a non-system volume of disk, or even to the removable media volume, so it is likely that we need to change VolumeID of other partitions.

Change current value to new value 5E37-EC11:

Cd c:\users\root\Downloads\VolumeID
Volumeid.exe c: 5E37-EC11

cmd volume id

OnceVolumeId utility updated the volume serial number of your system partition, close the Command Prompt window, and reboot your computer.

After rebooting, run TeamViewer and you will be assigned a new ID. Hope it was useful, guys!
