Months ago, I believe I might have gotten malware on my windows laptop.  Bought kaspersky total and did scans and found nothing.  Ended up doing a clean reinstall of windows 10 pro anyways.  When I did this, there was no internet.  I found out i had to download the wifi drivers.  So on another windows laptop, i downloaded 2 wifi adapter/drivers and then put it on a usb flash drive.  Then plugged that usb flash drive to my clean reinstalled laptop and was able to get wifi.  I then went to dell site and entered in my dell xps 15 9550 serial number to see what drivers i had to download.  I basically downloaded all the drivers that said important.  I downloaded some other drivers that were recommended.  But when I was doing this, I noticed there were some yellow exclamation marks on device manager so I know some drivers I didn't have.  I ended up doing a bunch of trial and error by downloading any driver on dell site that seemed important.  I then noticed many of those yellow exclamation marks were almost gone which mean almost all the driers i installed that is needed.  Then I went to windows updates and installed one of the optional drivers on windows update and after restarting my laptop, notice no more yellow exclamation marks so figure that was good enough.

 

I then downloaded kaspersky total again on the laptop.  Then downloaded chrome and other programs.  I been using this laptop for many months already but notice some lagging especially on chrome.  Now anytime there is a required windows update, I eventually do it.  But how do I know if I downloaded all the necessary drivers for my laptop?  Thing is everything seemed good last time when I set it up so I thought that was good enough.  But how do i know all my drivers are up to date?  Example the intel hd 530 graphics when i check task manager - performance shows the driver is from few months ago so that is most likely updated??  But the nvidia geforce 960m shows a 2020 date so that mean it has to be not update?

 

When i go to device manager and i click on processor, intel core (TM) i5-6300 HQ @ 2.3 Gigahertz, it shows the driver date as 2009?  Does that mean its not updated?  Got this laptop around 6 years ago so why does it show that?  No idea what this showed last time before I did clean reinstall.  But is this normal?  I know this laptop is an older laptop but still works fine but how do i know if all my drivers are up to date?  When there is a windows update, does it update those things?  What about the graphics card?  Again I didn't install all the drivers from dell site... but installed the important ones or the ones that looked important.  So what do i do now?
