Microsoft Windows 10 operating system last release, launched in April is messing sometimes, up to disabling some vital devices. While upgrading my personal and friends laptops, I experienced different issues :
Lenovo Legion Y520 (update OK) :
On this laptop (bought 2 months ago), the update went fast and the old windows files were deleted by the system. Everything worked fine.
Asus EeeBook X205TA laptop (update failed):
On this laptop bought two years ago, the update went fairly quickly, but once it was complete, the keyboard and the touchpad weren’t working any more. To make sure it wsn’t a hardware issue, I restarted, then I pressed several times the key F2, and once into the bios, I found that the keyboard was fine. I restarted Windows and found that the usb mouse was still working. With the mouse I launched the virtual keyboard with the following sequence : [Windows key / Settings / Ease of acces / Keyboard / Use your device without a physical keyboard / switch on]. Eventually I went into settings and in the recovery menu, I chose « Go back to the previous version of Windows 10 ». It worked fine.
Thomson NEOX13C-4RD32 Notebook PC (update long and difficult):
On this notebook, bought two months ago, since there was not enough space disk ( 32 GB eMMC) to install the update, I was required to insert a USB key during the setup. It took a while for the files to download, but the installation itself took about 5 hours, with the progress indicator increasing a couple of percents during the first two hours.
