Have received calls from this number on several occasion say that they are with Windows. THIS IS A SCAM. They try to gain remote access of your computer to hack your information. They tell you that they are getting error reports from your computer and need remote access to fix it. DON'T DO IT. Windows is a Microsoft product and; after a chat with Microsoft corporate; understand they Microsoft will NEVER INITIATE contact with you unless you specifically request contact. BLOCK THIS NUMBER! Also they have called back within minutes with a call that has no caller ID. It's the same demons.
