Steps to access the registry
1. Open the Charms bar by moving your mouse pointer over the right corner of your screen. Alternatively you may press Windows key + C on Start screen to open Charms bar. Then select Search.
2. Next, type ‘regedit’ in search box and click search button. Then click on the regedit (registry) icon on the left side of the pane.
3. Next, you have to confirm the UAC prompt click on the Yes button
4. Finally, the Registry Editor opens up. That are basically the complete steps to access the Windows 8 registry. From here you can uncollapse the folders you see below. This is how you would perform a registry tweak manually
We highly recommend beginners to make a backup and then get familiar with the registry by simply uncollapsing and browsing the registry for a while. When you are a little more familiar try applying a few tweaks manually. To do that you would open a .reg file with a notepad editor and then open up the entire path you see in the file e.g. HKEY_CURRENT_USER / System / CurrentControlSet
