Removing / Adding a user to AD groups, why does it take a long time to update?

Question

Active Directory

Greetings, colleagues
I have not dealt with Microsoft products for a long time ...
I have a windows server 19 with AD, a bus 10 car I add a
user to a group, for example myself for testing, I make a policy for this group I
execute 'gpupdate / force', 'gpresult -r'
policy applied (more precisely, not), writes access denied, well, it’s clear, I still haven’t added the
hell with it to the group, I reboot the computer, but no, I still haven’t added it to the group ... Automatically pulls up in half an hour or an hour somewhere then
the question is: how can you quickly shove a user into a group, or rather let the account understand that it is now in another group?

TGT ticket cache needs to be reset. It doesn't update instantly.
Using the klist purge command https://docs.microsoft.com/en-us/windows-server/ad...
