OK I knew going in that all new computers come with a complement of preloaded apps for which the manufacturer receives "inducements". They propose it is to  "Enhance the users experience" but in reality they are at best a nuisance and some are malicious usage trackers.. In the past these were relatively easy for technically literate users to eliminate. Now they have become much more sophisticated and devious and it took me about 5-6 hours to "disinfect" this ACER 5 slim machine. I use my laptop for serious work and cannot have tracking software of any kind so I am very careful what I load on my machines. I do not use Facebook, Twitter, Skype or even the Google search engine because of their  "behind-the-screens" mischief. SO I thought I have every thing cleared off except the pre-installed Firefox browser (my browser of choice). I was setting this machine up for my wife and upon boot-up the desktop and functionality has to "look" just like the old machine else she is not "happy" with the change. Even to the point of having the exactly same Firefox tabs open in the new machine as was open in the old machine. So after everything was prepared and all the other software installed I moved her old Firefox "profile" to the new machine and turned it over to her. After about 5-10 minutes Firefox locked up and would not exit. Even "task manager" could not clear the fault. I was able to force a "restart" but then Firefox would not load at all. At this point I have about 20 hours of time in this project. If I was doing this for a customer that would be about $1000 dollars for a $500 dollar computer. In the end and MANY hours of work later, after doing aWindows restore to the initial state of the machine and removing all the "crapware" again I used control panel to uninstall Firefox and deleted all its related folders including those in the hidden c:/user/username/%APPDATA% and c:/user/Public/downloads folder (delete everything there). I then downloaded Firefox from their website and set everything up again. So far all looks good but she uses Facebook so her footprints are being collected. I never use her computer for my work so that's OK. In the near future I will need a new machine and am not looking forward to having to set it up.Next time I will buy a Microsoft Surface Tablet I hear they have very little useless software preinstalled. This is not just an ACER problem HP is probably the worst. It seems everyone is trying to copy the Facebook model to collect as much user data as they can as there is a HUGE market for this data, The problem is once they have it it is lucrative for "hackers" to harvest it and they sell for nefarious purposes. I guarantee that your social security number can be purchased on the dark web.  Anyway be careful out there.Added 1 star to my review because this screen is the best I have ever seen on a laptop the "sharpness" is what makes this stand out. I don't know if is the IPS tec that improves viewing angles or not, just that the difference is quite noticeable. It far exceeds the Mac's vaunted "Retina" display. (I have both.)
