重置脚本
1、新建一个重置时间.bat脚本,然后进行编辑，内容是

@echo off

echo Delete HKEY_CURRENT_USER\Software\PremiumSoft\NavicatPremium\Registration[version and language]
for /f %%i in ('"REG QUERY "HKEY_CURRENT_USER\Software\PremiumSoft\NavicatPremium" /s | findstr /L Registration"') do (
    reg delete %%i /va /f
)
echo.

echo Delete Info folder under HKEY_CURRENT_USER\Software\Classes\CLSID
for /f %%i in ('"REG QUERY "HKEY_CURRENT_USER\Software\Classes\CLSID" /s | findstr /E Info"') do (
    reg delete %%i /va /f
)
echo.

echo Finish

编辑之后直接保存就行，然后双击运行就会重置试用时间，这样就可以一直试用了
每次试用结束都可以试用这个脚本
