Elevated rights in Anydesk (Request Elevation) are needed in order to be able to change the system settings of a remote computer, access the task manager, etc. That is, everything related to the global administration of the slave PC is provided by the extended rights function.
You can request elevated rights only in the advanced version of the program. The portable version does not give such powers, and the button will be inactive.
During a session on the remote computer, press the Request Elevation button in the client menu. Please enter the administrator password to gain access.
To avoid having to enter your password every time, log in to Windows as an administrator.
