como quitar la estrella de microsoft?

Open Windows Explorer by clicking Start -> All Programs -> Accessories -> Windows Explorer.

Browse to C:\Documents and Settings\All Users\Application Data\Windows Genuine Advantage\data folder.

Delete (or backup or move to another folder, if you want) data.dat file.

Create a new empty data.dat: You can create a new text file by (make sure you are at the right folder at above) clicking File -> New -> Text Document or right clicking on Windows Explorer window then click New -> Text Document. Then, either rename the file to data.dat. The original .txt extention of the text file need to be changed too. You can disable the hiding of extension of known file types, or follow the following steps to create a new file out of the text file:

Open the text document you just created.

Click on File -> Save As.

Change the Save as type to “All Files”.

In the File name, type data.dat

Click Save.

Go back to the Windows Explorer, at folder C:\Documents and Settings\All Users\Application Data\Windows Genuine Advantage\data, check that data.dat exists.

Delete the text file you created previously.

Set the attributes of data.dat to Hidden and Read-Only. Attributes can be set by right click on the data.dat file, and then click on Properties.

Windows Genuine Advantage (WGA) validation check has been disabled.

Note: The data.dat that are replacing the original data.dat can be blank text file or empty, or you may type whatever you want there.

With this hack (or crack if you want), Windows WGA piracy check will be bypassed and you can now download software from Download Center or apply updates from Microsoft/Windows Updates.
