Windows 8 is an operating system that features a completely different user interface when compared to older Windows operating systems. The Metro UI Start Screen and revamped desktop mode makes it rather confusing to perform even simple tasks for new Windows 8 users. If you want to open the Registry Editor in Windows 8, you must first go to the “Apps” screen. You can get to the “Apps” screen even if you are on the Metro UI Start Screen or the Windows 8 desktop.

Step 1
If you are on the Windows 8 desktop, point the cursor at the lower right corner of the screen. Click the “Search” option as soon as it pops up on the left-side of the screen. If you are on the Metro UI Start Screen, point the cursor at the lower left corner of the screen and click the right mouse button. Now select the “Search” option on the context menu.
Step 2
When you perform either of the above actions, Windows 8 will load the “Apps” screen. Type “regedit” into the search bar located on the right side of the “Apps” screen.
Step 3
Click the “regedit” search result on the left side of the “Apps” screen. If you see a UAC dialog box, click “Yes” to open the Windows 8 Registry Editor.
