Build 10532 is the latest Insider Preview build. The only reason why you get it is because you have asked to receive preview builds, or you are on Insider Preview build program.
You said you have reverted back to Windows 10 Pro.
Are you sure it is NOT build 10525 or 10240 ?
If it is Windows 10 Pro RTM you have reverted back to, and if you do NOT want to receive Insider Preview builds anymore, then follow these steps......
Start button > left side, click Settings > select Update and Security > click Advanced Options > scroll down a bit, under Get Insider builds heading, click Stop Insider builds.
