Windows is running DNS and HTTP test against www.msftconnecttest.com to check if it has internet connection or not. So if your internet can’t access this website, for example, in China, sometimes this domain is hijacking by GFW, then windows will show as no internet connect.
A quick fix is to disable Active Probe via modify registry.
Change below value from 1 to 0 to disable Active Probe
Today when I tried to upgrade my windows 10 1909 to windows 10 20H1, I got multiple BSOD. Based on the information on the BSOD screen, the BSOD were caused by some drivers (aksdf.sys, hardlock.sys, aksfridge.sys)
After investigation, looks like all these drivers were Sentinel Data Filter Device Driver/Aladdin HASP Data Filter Device Driver, Which provided by Safenet. I have no idea how these driver got installed into my computer, and I can’t remove them from control panel.
