The problem is that I can't type in Arabic from my new laptop at all.

I wish somebody (who knows the real answer) can help.

By the way, I'm using 3asq website in Arabic version.
but the problem still there.

Yeah, I can't type in Arabic at all.

BUT make sure that u are sure of your solution please, if u r sure, then give me it.

Otherwise, don't try if your solution will work or not please, I'll just be waiting who knows the answer surely.

ادخل على control panel اختار region and language

تظهر نافذة اختار kyebord and language

اختار change kyebord

ثم اختار add

وابحث عن اللغة العربية ثم اضفها

ثم ok ستضاف

I have windows 8.1. So, I don't know where control panel is.

جزاك الله خيرًا.

تم حل المشكلة، شكرًا جزيلًا لك.

السلام عليكم ورحمة الله وبركاته.

الله يسعدك يغلق للانتهاء

بالتوفيق
