How to Change Windows 7 Boot Screen Using Windows 7 Boot Updater

Now the wait is over. Since when Microsoft released Windows 7, no one was able to change the boot screen as it requires lots of files and certificates hacks.
"Windows 7 Boot Updater" is a program that makes it easy to update the Windows 7 boot animation and text. It is written in C++/CLI and requires Microsoft .NET Framework 2.0 and the Microsoft WIM library.

Features List:

Modifies the boot animation
Modifies the boot text "Starting Windows" and "Microsoft Corporation"
Will compile the animation from 105 BMP, PNG, GIF, or TIFF images
Does not require any other applications (like ImageX)
Designed to be idiot-proof by having numerous checks
Automatically backs up the modified files
Works for all versions of Windows 7: any language, any edition, 32-bit or 64-bit
Works even if your setup has the hidden "System Reserved" partition

The software is available for both 32-bit and 64-bit versions.

HOW TO USE:

You can change both boot screen and resume screen using this utility.

1. Download and run the program's exe file.

Download

2. You can change the text messages, remove them completely, change their color. You can also replace animation and background image.

3. If you want to change the animation you will have to make an animation! The animation is:

105 frames (if there are less frames the last frame will be repeated as necessary)
Each frame is 200x200px (resized if necessary)
15 frames / sec
First 4 seconds play once then the last 3 seconds play in a loop

The program loads a folder containing all the frames as PNGs, GIFs, BMPs, TIFs, or JPEGs images. The files will be played in alphabetical order. If you are numbering them, use the same number of digits for all numbers (e.g. 001, 002, ..., 103, 105). For 'historical' reasons, the animation can also be a folder containing a single BMP named "activity.bmp" that is 200x21000px.

HOW TO RESTORE:

If you get stuck forever in Windows Recovery Environment then you need to manually restore winload.exe. Here are the directions:

1. Once you enter Windows Recovery Environment press "Cancel" right away (while it is still scanning).

2. Click "Yes" on the warning that pops up.

3. Click "View advanced options for system recovery and support".

4. Select your keyboard types and click "Next".

5. Select an account (not "HomeGroupUser$") and enter password and click "OK".

6. Click "Command Prompt" (the last option) and enter following commands:

C:
cd \Windows\System32
del winload.exe
ren "winload~1.exe" winload.exe
exit

PS: Here C: in first line represents the system drive where Windows 7 is installed in your system. If you have installed Windows in any other partition like D: drive, then change the command to D:

7. Click "Restart" and you'll be able to boot into Windows again.
