I have win 10 in my notebook that has 4 gbytes. I do not use this notebook too often, but when i do, i am greeted with updates.Slow as it is with that little ram, it was passable for the little time i used it. Now with these constant updates beyond that October release last year, it seems that its getting sluggish. I cannot "X" and close certain sites...it has no effect. As for that recent change in windows explorer, its impossible to get past "Quick access" to my C drive and main folders. I've tried clicking on all those arrows to no effect. I was trying to get to my Download folder, but cannot get to it. I was thinking maybe a good scan might clear up some of the problem....but i cannot even get to the site to create a scan.The more upgrades, i feel it won't work at all. I can't add anymore ram to this Acer Aspire One-722. It has a 284 gb HD and 198 gb's free. I thought by removing the last couple of updates, it might resolve itself, but i went to security and updates and nothing appears there...so i cannot even remove the updates. This is a typical win 10 problem when it enters later updates. I'm writing this from my desktop with Win 7. I send an email from that desktop to myself and Thunderbird does not show it, Spam or inbox.
