windows 10

[unfazed]

I'm not really sure about that as it is part of the Windows 10 installation so there's no reason why it would have to be installed a second time unless the upgrade process failed at some point which isn't going to be a common occurrence.

And you go to a windows site to get the true information  :rollin

The number of upgrades I have had to fix tells me otherwise, many are caused by malware on the machines when the upgrade took place others were cause by anti virus programs not working correctly which in a few cases the install process did not catch.

At this stage any one who comes to me with odd ball problems from the upgrade that cannot be sorted in 30 minutes I back up the complete disk to a spare, wipe the original and install Windows 10 from scratch. Not only is it faster it is also more far more stable.
