Toto je občas nutností,pokud zákazník má notebook sice s licencí, ale vadným diskem, takže není možné použít firemní recovery, a přitom má nálepku s pravými windows, leč nečitelným číslem.
Method 1 of 9: Using Command Script
Open Command Prompt as administrator in start menu > all programs >accessories >command prompt . Right click on command prompt and select run as administrator
Type "SLMGR/REARM" (without quotes) and enter
Method 2 of 9: Linux
Boot the computer using Linux on a CD or USB drive.
Navigate to the System32 folder in the Windows folder.
Delete or rename two items: WgaTray.exe and WgaTray.dll.
Method 3 of 9: Task Manager
Run as an administrator with no other user accounts running.
Launch Windows Task Manager (Processes). Leave it open.
Navigate to to C:\Windows\System32, and find WgaTray.exe.
Right-click on WgaTray.exe, and select Delete. Leave the deletion confirmation box open.
Go back to Windows Task Manager and click Wgatray.exe.
Click End Process. When you are prompted for a confirmation to terminate the process, align the "End Process" confirmation box with the previous "Delete File" confirmation box, or at least have them close together. Do this because you'll need to do both actions quickly — at least within 2 or 3 seconds.
Click Yes in both boxes, quickly. Click on Yes on the Task Manager prompt (to "end the process") and then quickly press Yes on the deletion confirmation (to delete the actual file). You'll need to repeat this if you miss it.
Launch the Registry Editor. Click Start, then Run, and enter regedit.
Browse to the following location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify
Delete the folder WgaLogon and all its contents.
Reboot Windows 7.
Check your work. As a precaution, after you have followed the above instructions:
Go to Control Panel > Security Center > Automatic Update Settings.
Select the third option, "Notify me but don't automatically download or install them."
The next time the "Windows Updates" icon appears in the system tray, click on the icon and it will display a list of available updates. Windows won't automatically download and install them anymore.
If "Windows Genuine Advantage Notification Tool" is there, uncheck it and press enter to download everything else (if you want to). You can right-click to "hide updates" that you don't want.
Select "Don't notify me about these updates again", so that they will be ignored every time updates are downloaded.
Just remember, from now on, make sure to check the list of downloads so that you don't install any new versions of this "tool".
Method 4 of 9: Command Delete
Try system restore first. If you have only just installed Windows Genuine Advantage notifications, simply using the system restore function will remove the program. Then refuse to accept the WGA update next time Windows updates. Otherwise, proceed as detailed below.
Open a Command Prompt window. Click on Start, then Run. Type CMD and press OK.
Change Directory into the System32 Folder. Type "cd \windows\system32" (without quotation marks).
Open Notepad window. Type the following lines:
taskkill -IM wgatray.exe
Highlight and copy the three lines above to the Clipboard.
Paste the contents of the Clipboard to Command Prompt. This should kill the wgatray.exe process from the Taskbar and immediately delete both files wgatray.exe and wgalogon.dll.
Method 5 of 9: Executing a Batch Script
Right-click on your desktop. Choose New, then Text Document.
Enter the name as "remove.bat" without the quotes.
A message should appear saying that you are changing a file type. Click Yes. If the message does not appear, and the file icon is a picture of a piece of paper, then you need to enable "show file extensions for known file types" in the Windows Explorer Tools ->Folder Options dialog.
Right-click on remove.bat and select Edit. Notepad will open.
Paste the following lines into Notepad, then save and exit:
taskkill -IM wgatray.exe
Double-click on the remove.bat icon. A command prompt window should briefly appear, then close automatically.
Method 6 of 9: System Tools
Open System32 by either of the following methods:
Click Start, then Run. Type "system32" (without quotes), and click OK.
Find system32 manually by clicking Start, My Computer, (C:) (or whatever your drive letter is), WINDOWS, then system32.
Hide extensions. In system32, go to Tools, then Folder options. Click on the tab, View, and uncheck "Hide extensions for known file types" if it is not already.
Check to make sure the window that comes up has a full screen of various files. The files are in alphabetical order, which makes it easier to locate the specific file.
Find WgaLogon.dll. Rename it "WgaLogon.dll.bak" (without quotes).
Create an empty copy of WgaLogon.dll.
Right click on a blank space in system32 and select New, then Text Document.
Leave the text document empty and label it "WgaLogon.dll" (without quotes). Press Enter (on your keyboard).
You may get a warning from the above step that says, "If you change a file name extension, the file may become unusable. Are you sure you want to change it?" Click Yes on this warning.
Be ready to complete the next two steps very quickly.
Find WgaTray.exe in system32 and delete it.
You will then have 5 seconds to find WgaTray.exe in the Task Manager.
Note that if you remove the files mentioned above while you are in Safe Mode, the next step is unnecessary.
Immediately open Task Manager. You can do this three different ways:
Press Ctrl, Shift, and Esc simultaneously.
Press Ctrl, Alt, and Delete simultaneously.
Right click the Taskbar and select Task Manager.
Click on the process tab and select WgaTray.exe. Click on End Process.
Note that if you take longer, do not panic! All that will happen is that WgaTray.exe will keep reappearing in the processes list (i.e. you won't be able to delete it as required). To remove the notifications after this, return to system32. You will find two files:WgaLogon.dll.bak (the one you renamed) and an Application Extension (0KB) called WgaLogon.dll. Delete the Application Extension, rename WgaLogon.dll.bak to WgaLogon.dll and repeat the process at a greater speed, from deleting WgaTray.exe from system32.
Restart your computer when finished. All the notification messages should be gone.
Method 7 of 9: Renaming
Open a Command window. Click on Start, then Run. Type CMD and click OK.
Open Notepad. Click Start, then Run, and type NOTEPAD. Click OK.
Type or copy the following lines into the Notepad window:
rename wgatray.exe wgatray.exe.bak
rename wgalogon.old wgalogon.old.bak
rename LegitCheckControl.dll LegitCheckControl.dll.bak
taskkill /F /T /IM wgatray.exe
Leave a blank line. Make sure there is a blank line at the end of the text document, right after the last line of text.
Select all the text (Ctrl-A) and copy to the clipboard (Ctrl-C).
Paste the clipboard into the CMD window. Right click and select Paste, or Press Ctrl-V.
This should kill the wgatray.exe process and delete the files it uses.
Method 8 of 9: Renaming (Graphical Interface by selection)
Select "My Computer" on an Admin account of your Windows-computer.
Select the Windows folder of your "Local Disk (C:)" drive.
Find and select the "system32" folder.
Right-click "wgatray.exe" and rename this file as "wgatray.exe blocked" (without quotations).
Right-Click "wgalogon.dll" and rename it as "wgalogon.dll blocked" (without quotations).
Method 9 of 9: Alternative
Launch Windows Task Manager.
Locate the process "wgatray.exe" and end it.
If you are unable to end the process then try to rename file wgatray.exe to aaa in both c:\Windows\System32\dllcache and c:\Windows\System32 directories.
Type regedit in the Run box to open Registry Editor.
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify key and ??
Delete the folder WgaLogon and all of its contents.
Restart the PC normally.
Delete the file aaa from c:\Windows\System32.
Delete the aaa from c:\Windows\System32\dllcache.
