A small program that does not require installation, which will help change the default image of the Windows login window (Logon Screen - in wines 7 this is a blue background with grass and a bird).
Specify any image (jpg format, no more than 256 Kb, preferably the size of the resolution of your desktop,
for example 1024x768 (in principle - not critical - there will be autosize, but so that the proportions are not distorted ...),
if more or less - you can edit it in any graphics editor, even in Windows MsPaint.exe) and press "Apply".
To see what happened - Ributim PC.
To cancel the installation (return the default Windows image) - click "Reset" and reboot.
P.S. in Win7, you can’t do it, just press ctrl + alt + del to see the changes or you can click "Test". Tip: It is optimal to specify the same picture that works as your desktop background, but you can use any other.

the program copies the specified JPEG to the system folder C: \ Windows \ System32 \ oobe \ info \ backgrounds \ (or ..SysWow64 .. if the system is x64) + makes changes to the registry using the key HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Authentication \ LogonUI \ Background (or in HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ ... if the system is x64).
In principle, all this can be done with pens, but for a long time.

Auto-change occurs if you run GuWinLogonPic, indicating to it on the command line the path to the folder that contains the jpg files. With this launch, the program does not show any messages or windows, it looks for * .jpg files there, selects random, makes a picture change in the system and closes. It is important that the parameters are set correctly, as the program will not show any reaction to errors if the command line argument is not empty. You can create a cmd file with a command line like GuWinLogonPic.exe c: \ MyLogonPic and experiment by running it, and then pressing Ctrl + Alt + Del to view the changes. If UAC is enabled in your system, then a window with elevation of rights will pop up, this is normal. To create an automatic change of images at each boot, you must use the regular capabilities of Windows Scheduler. Example: - Create a folder somewhere, for example, "c: \ MyLogonPic" - Put the pictures you like in jpg and the program GuWinLogonPic.exe itself - In the Computer Management snap-in \ Task Scheduler \ Building Planner Library - create a simple task , for example, with the name "Change images at login" = When to start: when the computer starts = Action: start the program = Program: specify the full path and name of GuWinLogonPic.exe (for example, c: \ MyLogonPic \ GuWinLogonPic.exe, or use the "browse" button ) = Add arguments: c: \ MyLogonPic (if the path or folder name contains spaces, then it should be enclosed in quotation marks, for example, "c: \ Program files (x86) \ My logon pic folder") = At ​​the end of the wizard, check the box "open Properties" or after creating a task - click on it off. mouse - "Properties" = Set "Run regardless of user registration" and checkbox "Run with the highest permissions" - you will need to enter your account password = Leave the rest of the task settings by default To check how your task works - click in the right window of the scheduler "run" and press Ctrl + Alt + Del to request Motor changes (repeat several times). Now you can restart the system several times to see the program in action. Notes: - Although the program supports Unicode, it would be better for the folder name and file names to be English and without spaces (the eternal guarantee of successful work in Windows since 3.1) - Files should not be more than 256 Kb (if more, you can optimize the size with any graphic editor or for example AcdSee program in editor mode (search here)) - File and folder attributes must be standard (no hidden or system attributes or their combinations) - The task creation account must have administrator rights in the system - "c: \ MyLogonPi c "- is given only as an example, the name of the folder and the path to it can be any -" Perform with the highest rights "- is necessary in order to give administrator rights to run the program, because it needs such privileges (+ this will prevent UAC) - Account password when creating a task - it is not sent anywhere it is necessary only to the task manager to perform a task from a specific user - GuWinLogonPic.exe does not have to be in the folder with pictures Additionally: - This mode It can also be used by domain administrators to distribute their company logo to users' workstations (if you make a void through the registry and file system). In this case, there should be only 1 picture in the folder with pictures, and the launch is registered through group policies when loading users PC. Or it is better to use the new modes of version 0.3.1 - at the command line immediately indicate the file with the picture.

The 3-rope simply lives on the desktop (on top of all windows), occupying from 4 to 6 megabytes in the computer's RAM.
You can choose one of two variations of the Wofty image, which differ in character and, accordingly, in their behavior (in particular, the Wofty-baby variation can sometimes fall asleep after midnight).
Most of the options for controlling the animal are available through the drop-down menu (after right-clicking on the animal).
You can set high or low priority for processor loading, which is especially important for relatively slow computers and laptops, as well as disable or enable sound for Wofty.
Installation Procedure: No Installation Required
1) run wofty.exe and enjoy
2) if the animal is not visible at startup, delete the config file. ini in the data folder and try again!

Additional Information: - For relatively slow computers and laptops, it is possible to set a high, or vice versa, low priority for processor loading. - You can use it with or without sound.
