My PC has viruses and I'm wondering if it's necessary to factory reset with clean all drive and fully clean all drive choosed or I just need to choose clean drive where window is installed and only remove all files?

fully clean drive

After doing a "fully clean drive" in resetting pc, my sign in screen and name are still displayed. Why wasn't that removed, "cleaned " as well? Is it a hardware or software issue?

 

Factory Reset Full Clean

Hey guys! So I was trying to do a full clean factory reset last week but I forgot to plug in the charger. After turning my laptop on, it brought me back to my original settings and files but I can no longer do a full clean factory reset. An error popped
up saying that, "There was a problem resetting your pc" when i tried redo the factory reset. I tried doing a system repair but it said I was missing something. I want to fully clean my acer laptop if possible.

Thank you for your input!

 

Windows 10 Reset and "Fully Clean The Drive" on SSD

Hi,

I have a quick question about the "Fully Clean The Drive" option for Windows 10...

I have read that if you are planning on selling your computer you should reset Windows 10 and select 'Fully Clean The Drive'. I have read this is 'similar' to running format.exe c:\ /P:0, which would overwrite the whole drive
with zeros, making data recovery from a traditional HDD pretty much impossible.

My questions are

1) What exactly does fully clean the drive do? Does it overwrite the WHOLE drive or just delete user files and overwrite the free space? Because if it were to overwrite the whole drive how could it reinstall windows because there
would be no remaining data on the drive.

2) How does fully clean the drive work on SSD's? A single overwrite on a SSD would not be sufficient to sanitise the drive unless a TRIM command was also issued. Would fully clean the drive issue a TRIM command?

I guess my main question is how likely is it you can recover user data after you 'fully clean the drive' on an SSD?

Thank you in advance!
