Windows 10: How do I block my domain from my old PC?

I had a old PC and after I moved schools I kept my old windows school laptop and I want to use that laptop again for new purposes, but my domain still joined in that PC, so how do I block my domain from managing my old PC so its all mine again and I get going, I used my old PC for online school.

Block domain in Hotmail

I've added icu.com to the blocked list but I'm still getting the junk.

The junk mail is always in the format "L: [email protected]". The "xxx" is different in every message.

I tried to add "*@*.icu.com" to the blocked list. (i.e. using wildcards) but got an error message telling me that the e-mail address was not formatted correctly.

Did I need to add the domain icu.com differently so that everything gets blocked?

 

UnattendedJoin error: failed to find the domain data (0x6e)

Thanks for the suggestion! I don't want to add a domain account, as this is a generic unattended install that will be used for all company machines. Do you think it's possible that the computer would join the domain if, instead of using UnattendedJoin in specialize, I used your steps but left out the specific account? The other thing I was thinking was to use a generic account to allow the domain join during the specialize step. I added a machine password in the UnattendedJoin component, and instead of getting the error listed above, I got an authentication error, which makes me think I could probably do a secure join instead of the unsecure join. Thoughts?

 

Block domain in Hotmail

Not much you can do yourself, these domain names are faked and/or randomised intentionally.
Sure, you can try by blocking a domain but almost instantly that will change and you are back to square one.

You will find that your long list of blocked senders and domains will be totally useless in a very short time.
Sad but true unfortunately.

Fortunately the Mail providers filters are much more effective these days.

What has worked for me, to some extent, is to severely limit where your Email Address(s) are known or exposed. Spammers have Software to auto-farm Email addresses from various sources.
