Hi Андрей Ракитин,
Thank you for throwing light on it, kindly try to uninstall Creative Cloud app and let us know if you see any change in Media Player Classic's behavior.
Please share the results.
I didn't uninstall it, I just quit it from the task bar and everything is OK. But I need Adobe CC from time to time, I don't want to open/close it every time.
Kindly share the below mentioned details, so that we can assist you appropriately.
- OS version:
- Screenshot of Task manager/Activity monitor sorted by CPU utility.
I would be waiting for your response.
We would try to create a new account and disable all the third party services running on your machine, and check if your MPC is running fine or not.
- Create a new admin user account: Create a user account - Windows Help
- Disable startup items, services | Windows, reboot the machine
We would be waiting for your response.
I'm sorry, I had lots of work to do. Well, I did that and it worked. So I supposed that was some problems with codecs. I reinstalled my codecs (K Lite 11) and it worked. Now everything is fine. Case could be closed.
