-Still seeing many failed Win 10 upgrades. Before you attempt this please make a “disc image” backup of your current system. With this you can return the computer to it’s current state should the upgrade go bad. Use an external hard drive for storing the backup. Step by step instructions for creating a disk image backup in Win Vista/7/8/10 here: http://www.howtogeek.com/howto/4241/how-to-create-a-system-image-in-windows-7/

-Electricity here is inconsistent. To avoid serious problems that this can cause get an UPS (universal power supply) to supply power to computers, external hard drives and monitors. Providing 220 volts regardless of incoming surges or drop-outs, it also stores enough power to allow you to close open files and shutdown properly in the event of a power outage. Standard “surge protectors” are insufficient for computers. UPS units, with 2 sockets, start at around 50 euros. Plugging an extension cord into a UPS may place too great a load on it. If necessary, get a UPS with more sockets.

-Sent emails not arriving, updates or Skype stalling, or unable to use sync or cloud services? This may be the result of a poor quality connection or slow upload speeds. Poor quality may cause some services to decide you have disconnected and drop you before the task is complete. Run the test at www.pingtest.net , note this test requires Java and Flash Player to be installed. A score of “B minus” or lower indicates your connection lacks the quality required by some popular services. Check the results details for explanations in plain language of any problems found. If the test shows a poor latency score, or many dropped packets, you can expect some problems uploading. Then check the upload speed at www.speedof.me . To give you an idea of what upload speed you require, Skype will probably be the biggest use of uploading you do unless you are a game player., Skype recommends 300kb/s for basic video calls, 700kb/s for group calls and 1.5mb/s for HD calls.
