For those who do feel comfortable, when you're on the Start screen, type regedit, click Apps on the right-hand side of the screen, then click the regedit.exe icon that appears on the left side of the screen.
A security window appears asking if you want to allow the Registry Editor to make changes to your PC. Click Yes, and the Registry Editor launches.
Now navigate to
See if there's a key called Personalization there. If the key already exists, don't create another one. Instead, follow the instructions in the next paragraph. If the key doesn't exist, you'll have to create it. To do so, click Edit --> New --> Key. That creates a new key, but it will have a name like "New Key #1." You have to rename it. Right-click it, select Rename, and rename it Personalization.
Now that the Personalization key is there, create a new DWORD value under it called NoChangingLockScreen. To do that, right-click the Personalization key and select New --> DWORD (32-bit) Value. Rename the DWORD value NoChangingLockScreen. Double click-it and change its value from 0 to 1. Now exit the Registry Editor.
Setting the NoChangingLockScreen DWORD value to 1 prevents the lock screen image from being changed. Click to view image.
Log out of Windows or restart it, then log back in. The lock screen background shouldn't be changeable -- consider it locked. If you want to allow the background to be changed in the future, use the Registry Editor to change the value of NoChangingLockScreen from 1 to 0.
6. Kill the lock screen altogether
Not a fan of the lock screen? There are plenty of people who don't find it useful and would prefer to bypass it so they can just sign into Windows and get straight to work. You won't find a setting to do it. Instead, you'll have to use the Registry Editor.
All the caveats about using the Registry Editor outlined in the previous tip apply here, so keep in mind it could be dangerous to use it. However, if you're comfortable using the Registry Editor, follow the instructions in "Lock the lock screen image" above to launch the Registry Editor, and, if you haven't already done so, to create a Registry key called Personalization in
Create a new DWORD value under the Personalization key by right-clicking it and selecting New --> DWORD (32-bit) Value. Rename the DWORD value NoScreenLock. Double click-it and change its value from 0 to 1. Now exit the Registry Editor.
The new setting should take effect immediately. The next time you reboot or wake your PC, you won't see the lock screen. Instead, you'll go straight to the Windows sign-in screen.
7. Bend File Explorer to your will
Windows 8's File Explorer file manager is different from the old Windows Explorer in more than just name. It's gotten a complete makeover, notably by the addition of a Ribbon interface that puts many tasks, features and views in easy reach. Following are my favorite ways to get more out of it.
But first you need to make sure that File Explorer displays the Ribbon, because it might not be turned on. To turn it on, press Ctrl-F1 or click the downward-facing arrow on the upper right of its screen. The Ribbon displays, and the downward-facing arrow turns into an upward-facing arrow. To turn it back off, press Ctrl-F1 again or click the upward-facing arrow.
