I disagree with you on McAfee. Because after testing everything out there. McAfee was the only one to not hog the CPU when you boot up or it decides to suddenly scan like the Stupid Windows Defender likes to do.
I do not go by what the likes of PCMag or some forum decides. I have one machine reserved that is for nothing else but software testing for clients.
I guess I'm not the only one with this problem. My 2015 Asus zenbook 305f (256ssd, 8gbram) (pre packaged with win10) is a week old. Once I did the Nov 2015 win 10 update I have noticed a 30s wait between typing in my pw and waiting for the desktop to appear. Prior to that it was maybe 6 seconds. I disabled all startup programs. Have enabled/disenabled fast startup, disabled/enabled the requirement for a pw at login, but still no change. What gives? I notice that in msconfig I have 194 services running at startup (95% microsoft, a few intel/asus and 1 for mozilla/adobe)
However, if just do a reset, the login screen is maybe there for 5 s.
I find this frustrating as my 2009 macbook pro with a 2.26 intel core duo and 8gb ram with a ssd takes like 3 seconds... I would think that a computer 6 years newer would surely be quicker than 30s...
Any other suggestions?
Yes I have McAfee Live Safe and have had no issues with it at all has a good record in fact all of my systems I look after in the house have McAfee on them including all the smartphones we use.
When big upgrade came I did not even shut down McAfee and once upgraded it came back in.
Check that your drivers are up to date as I have an automatic driver updater installed and on every upgrade and the update just installed one driver updated its self.
This is on all laptops and tablets we use for business and pleasure
1. Run a system restore. Pick a date when you did NOT have this "slowness" as your restore point.
System Restore Windows 10
2. If nothing has helped, do a Rest option.
Left click at Start button > left side, click Settings > select Update & Security > left side, click Recovery > right side, under Reset this PC, click the Get started button.
