Quote:W10 upgrade went fine.
If one wishes to start with a "clean" system, a new installation is better than an upgrade.
Installing new is also possible with W10 ... you have to register on an MS server in order
to get the W10 key (which you need for the installation from a downloaded iso-image).
After that, you have to reinstall all applications. While this can be a real PITA (depending on
how many different programs you need), you have the chance for a nice and tidy installation
to start with.
I bought a small 11'' notebook (mainly for travelling ... to backup images and do a bit of processing).
It came with a preinstalled W8.1 ... I clicked the "update me" button straight away ... anyhow,
the W8.1 installation decided to first bring all the missing 8.1 patches in, before upgrading.
So I ended up with about 7.5Gb download ... half of that to update W8.1 to the latest
patchlevel, and the other half to install W10 ... and a bit to bring W10 to the latest patchlevel.
So far, the only really strange thing that happened to me with W10 was while I was using
the prerelease W10 builds. I had (for testing) an encrypted systempartition (with truecrypt).
When a bigger W10 update (in fact an entire new prerelease) was published, it would entirely
and repeatedly fail to install. This only stopped, after I unencrypted the systempartition again.
Then it would install. (After this, I could again encrypt the partition).
Just my 2cts on W10 ... Rainer
