Hello Evgeny Shupik, Thank you for posting in Q&A forum. Based on the description, you set the setting (Computer Configuration->Policies->Administrative Templates->Windows Components->Remote Desktop Services->remote Desktop Session Host->Session Time Limits->*Set time limit for disconnected sessions: 2 hours) within Default Domain Policy, and you want User1 (as example) do not apply this setting.
To meet your needs, here are two options for your references.
Method one: You can create one OU, where the computers used by users who need to apply a time limit policy will be moved to this OU. And create one GPO and link this GPO to this OU.
Because the policy you created is a computer policy, the objects included in the organizational unit should be computers.
Method two: Create one new GPO (such as GPO1) and link it to domain. Create one group (such as group1) and put all the domain computers except user1' computer into this group. In this GPO1, add this group1 via Security filtering. Make Authenticated users have read permission. Make this new group have read and apply group policy permission. I hope the information above is helpful. If you have any questions or concerns, please feel free to let us know. Best Regards, Daisy Zhou
