Dell Vostro Laptop Extremely Slow After Windows Update High CPU and Growing C Drive
I have a DELL Vostro laptop but after the last Windows Update my system has become extremely slow even opening a single Chrome tab spikes CPU usage to 100 percent and my C drive which only has Windows keeps increasing in size day by day should I reinstall Windows completely or is there any other way to fix this issue

* Contact GHN (Get Help Now) on right. This must be done to create a Dell case tied to the unique computer Service Tag number. For this specific issue, out of warranty customers will be assisted by the GHN technical support team
* Push through the GHN AI questions until it sends you to a GHN agent
* Once connected to the GHN agent, explain the issues you faced after installing BIOS 1.27.0/1.29.0. Ask the GHN agent to look up Dell article 000423130
