Just my take here: Having no issues whatever with this Windows 10 install, I did an Reflect Image & out of interest RE: This thread I installed Driver Booster & let it do its stuff, there were dire warnings to update & install Pro as my NVIDIA driver was exploitable (I didn't) - Anyway I ran the PC for a couple of days having had many drivers updated yet no discernible improvements including network speeds etc.
O&O Defrag latest did have issues running slowly, nothing was improved - Anyway as there were unwanted bits & RougeKiller found bits of malware I decided to image back as I saw no improvements to a state I knew worked OK. For the first time I can remember Reflect failed running Windows PE? and I got a repeated black screen.
This required using a boot medium & went back a few days & all is well - My initial assessment it messed up a really well working PC & as there were no backups made by the program? (As I could boot into damaged Windows with Boost changes) - I often think leave well alone, if its running well leave it? As it was I always have images but others may not have but this was just my experience. Could be a one off? Never again
EDIT: For fairness to me & a morbid fascination, I'm going to do the same thing again tomorrow & see if the same issues occur as other factors could have been involved? If I'm never seen on here again, well..? Of course nothing is proved apart from it may cause issues on this PC.
Sounds like you have other problems, not associated with driver updates.
