How to clean cookies on windows 8?

[Dominic]

Ctrl + Shift + Delete will let your clear the history on any web browser. However, that will not solve the problem.

Visit Programs and Features (Windows key + R, type appwiz.cpl, press Enter) then uninstall any programs you don't need. Get rid of any uneeded add-ons (Windows key + R, type inetcpl.cpl, press Enter). Click the Programs tab then click Manage add-ons. Disable any toolbars or extensions you don't need.

Open Task Manager (Ctrl + Shift + Esc) then click More details, then click the Startup tab. Disable anything you don't need to start when the computer starts.

Might also want to try a clean boot to see if it helps.
