Hi RazvanCio,
- Which edition of Windows 7 are you using?
- Have you done an upgrade installation from a previous Windows setup?
We have tried replicating the issue and we are not facing it at our end. So I would suggest you to make the appropriate animation changes
and then perform a clean boot. Then do check if rebooting the computer affects the changes. It is possible that a third party program may be over-riding the settings. You may check the settings after clean boot and let us know if they have changed.
You may check in a clean boot state.To perform the clean boot follow the step 1 mentioned in the below article and then try checking in this clean boot state -

If the issue gets resolved check which non-Microsoft service is causing the problem; referring to the article and following other steps.
**** After you have finished troubleshooting, follow these steps to reset the computer to start as usual:
a. Click Start, type msconfig.exe in the Start Search box, and then press ENTER.
If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
b. On the General tab, click the Normal Startup option, and then click OK.
c. When you are prompted to restart the computer, click Restart.
Hope this helps.
Thanks,
