The are  two possibilities:

First, your name is not in your friend's contact. although you have him/her in your contact but if your name is not in your friend's contacts, then you can not see your friend's status.
Means if you want to see the status of your friend, ask your friend to put your name in his/her contact.

Second. Your name is in your friend's contact list but in your friend WhatsApp Privacy status setting, your name is in the list that can not see status of your friend. In this case it means that your friend intentionally blocked you from seeing his/her status.

Too much hard drive activity windows 10

If you are sure there is no virus on your Windows computer, no your application is running in the background, like Antivirus on the scanning process, etc.  and you still see the hard drive indicator is always busy. or from the task manager the disk activity get the high value 90% or more. whats is the cause?.



One possible cause is : the computer is optimizing your hard drive, defragmenting  the drive. This is happen because at default Windows 10 has optimization schedule automatically which it is set one time a week.

You can set/change the optimization schedule, or you can stop/turn off it (manual defragment process).
