Quick overview:
After you have booted up your computer, a login window appears in which you can log in with your user name and password. The background is usually blue, but this can be very monotonous in the long run. Windows Tweaks has now found out how you can use your own image:
1. Click one after the other on Start > Execute and type in the command line that appears regedit in. A program appears in which you can double-click through the various keys of the Windows Registration database can shimmy.
2. Go to the key HKEY_USERS\ DEFAULT\Control Panel\Desktop and click with the right mouse button on a free area in the right-hand pane. Then click on New and create with the help of the option Character string a Reg_Sz value, which they simply Wallpaper name. However, if this value was already there or not for both, the following applies: Double-click on it!
3. Now enter the hard disk path to your favorite background image in the line that appears. If your image startrek.bmp is located in the directory C:\My Pictures\Science Fiction, you must enter C:\My Pictures\Science Fiction\startrek.bmp and write it down. Click on OK and the new image is applied.
It is important to note that only BMP images work here. Image formats such as JPG or PNG are completely ruled out. However, it is easy to convert these images to BMP, even if you do not have a professional editing program such as PhotoImpact:
1. Click on the image with the right mouse button and select Open with... and look for the Internet Explorer from
2. The image now appears in full size - click on File/Save as and search under File type the menu item Bitmap from.
You now have to adjust the path of Wallpaper as described above and your new bitmap is already applied. From now on, it will greet you every time Windows starts up.
