On windows 10 control panel can I block browser from taking cpu for bitcoin mining?

on a browser I can click "ok" button to donate my cpu for bitcoin mining.
When I press "ok" my computer gets slow.

Windows defender did not detect this a virus

So I think I could be donating my cpu by keeping a browser window open
any website can be taking my cpu for bitcoin mining without an "ok" button

I keep many browser windows open
On windows 10 control panel can I block browser from taking cpu for bitcoin mining?
Please dont tell me it is a virus and to check for other viruses
Maybe I can just use a non admin regular windows user to ban cpu usage from my browser

It uses quite a bit of computing power to create a fraction of a bit coin. People use dedicated computers for this, not their main computer. That is why it is slow.

Most information I have read suggests the cost of electricity for the computers is greater that the value of coin created. Be careful.

I rather have the browser has some plugin to detect besides the host AV.

There are a few ways to block it. The fastest method is to just install No Coin in Chrome. But the plug-in was only blocks Coin Hive.

Just like No Coin, minerBlock Chrome extension is another open-source tool that you can use to block cryptocurrency mining in the web browser. These extensions currently list a few popular miner domains to their list, and they are expected to add more once they get popularity.

Also has some ad blocking software. AdBlock is one instance.

See summary in https://www.google.com.sg/amp/s/fossbytes.com/block-cryptocurrency-mining-in-browser/amp/
BItcoin mining through means of scripts housed on websites and executed without your consent is a growing problem and AV software will respond to it / has slowly begun to recognize this.

"On windows 10 control panel can I block browser from taking cpu for bitcoin mining?" - no. You could setup alerting for high CPU usage to become aware in time. Start perfmon and look at the options. Please note that if you are unfamiliar with perfmon, you will need to do a little reading. There are plenty of resources on the net that will describe how to set it up as a team with scheduled tasks that get triggered by it and perform actions like sending a warning popup.

"Maybe I can just use a non admin regular windows user to ban cpu usage from my browser " - you should always be using a non-admin user. However, there is no CPU limit per user possible - not for admins, not for restricted users.  To limit resources of your browser, you would need to run the browser in a virtual installation of windows, say Hyper-V. Virtual machines can be resource-limited, fine-grained, even.
