喜欢卡巴斯基的朋友，一不小心，卡巴key就被封掉，下面笔者就说一下永久使用巴斯基无需激活码授权文件的方法，但是更建议大家买正版，现在已经很便宜了。

方法1：手动修改注册表

1.暂时关闭Kaspersky.
2.打开注册表,去掉下面的三项. 
HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\LicStorage
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\RNG
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\SPC\Certificates
3.再运行Kaspersky, 选择 30-day trial key and activate.
4.When the 30-day trial key expired, run these steps again.

方法2：批处理 

写个简单的批处理..

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
@echo off
@reg delete HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\LicStorage /f
@reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\RNG /f
@reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\SPC\Certificates /f 
pause & exit

复制红色部分并保存为*.bat运行后就可以了，大家以后就不用为找激活码和授权文件而到处求人了。
