I've serviced a couple of x64 W10 laptops for my sister.
On one, Mcafee had run out and she wanted freebie Avast instead. I took Mcafee off and enable Defender AV instead since the W10 version seems favourable these days.
On the other lapppy, Lenovo G50, it had started being very sluggish on boot.
I emptied Temp, both Windows and User account and Recycle Bin.
I defragged, albeit only 2%.
Did sfc /scannow resulting in no issues found.
Boot scanned with Defencder AV having removed Avast first.
Scan with SuperAntiSpyware
Scan with Malawarebytes.
Still sluggish!
Then what I did was take the HDD out, wiped the all contacts with an alcohol swab, put the drive back in and the boot is much improved.
Oxide film build up on HDD contacts causing resistance across SATA contacts seems the logical cause. The same way you're not supposed to touch a penny battery with your fingers when you put one in a car's fob.
