The computer can only log in to the specified QQ number setting method

One & sect; delete “WizardCtrl.dll” this file in the installed QQ file. In this folder, delete the QQ number file that you don't want it to be mounted, and keep the QQ you want to use, so that QQ without a number on the computer can't be mounted. If you delete “WizardCtrl.dll” I want to log in to the QQ number that I don't have on my computer. There is no way, you only have to reinstall QQ. It is best to back up this file and restore it when you want it!
This method I tried is not bad. In fact, you only need to modify the name of WizardCtrl.dll, I usually modify it into WizardCtr1.dll, is it very confusing? Hey. If you want to log in to another number, just change the name of WizardCtrl.dll back.
Second & Sect; can use the folder's "security permissions" to solve
1, to ensure that the QQ installation disk is NTFS format, if not, please convert: convert c: /fs:ntfs
2, first let the normal QQ number login, there will be a QQ directory in the QQ directory
3, modify the security attribute to deny everyone to write to the QQ directory
4, modify all directories and files under QQ, allow Everyone has full control
5. Modify the user right to log in to the computer to be a non-ADMINISTRATORS group user
. Other QQ numbers cannot be written to this directory, so you can't log in.
