Sounds like Windows update.

If you open task manager (ctrl+alt+del) and got performance tab. Here you will see SVChost (process) and wuaserv (service) using large amounts of processes.

Here are image of Performance Tab
i dont see (wuaserv, service)
only svchost

Can i turn off Windows Update service? so the svchost is turned off, and not using my CPU and RAM , like 5GB on idle thats almost all my ram...

GTA5 even uses 5-6GB... like hello Microsoft?

If you open the CPU tab you should see it listed there.

You can turn Windows update off while you are using the PC but I wouldn't advise that you ignore updating Windows.

As you have just installed Windows the updates are going to take 1-3 days to fully update. I suggest leaving it running overnight and just leaving it until it finishes.

You right click it and select end process.

However, if you don't update Windows your PC is at greater risk of being infected, so I strongly advise that you update it.

Thank for help.

But do you think updating Windows 7, with Microsoft , will make it better? Everyone knows Microsoft windows updates when u install them and your computer is like Brick, Running slow.

But i will try install them now.

Do i need to go services. ? and Click Windows Updates " Manual " Disabled??
so next time when boot up pc all my WindowsUpdates is disabled can i do this?

My advise is don't install the recommended updates but definitiley install the important updates because they make your PC more secure.

I would not set Windows update to manual in the services tab. Best to open Windows updates and change settings there.
