Since yesterday, I have been working on getting my 6 year old XPS 435 MT to run Windows 10.
The 'Get Windows 10' App, never showed up, despite trying all the troubleshooting steps outlined on microsoft.com.
I had downloaded the 3.8 GB ISO already (international version).
So, after wasting 3-4 hours, I simply converted that ISO into a USB bootable version (using the Media Converter - or similar named tool from Microsoft's website).
So, after that, I double clicked on the setup from the USB pen drive and the process started.
I wanted to preseve all my programs and data, so I chose that option (the first one that came up).
Also, I did not choose to download needed updates, since I expected that to slow down the whole process. I have a 1 Mbps connection - not exactly fast.
So, after around 35 minutes, I was into the desktop.
1. Graphics card - some generic driver was used. Downloading AMD's 15.7.1 driver was an excruciatingly slow process. The speed was roughly 30 Kbps. Finally managed to download the file after 3 hours (size 245 MB).
That took care of the graphics part.
2. Kaspersky itself popped up a message that I should use a version compatible with Windows 10, so I started that download and that one took a good 1.5 hour as well.
I noticed that all the download speeds were around 500 Kbps, even if I am trying to do multiple downloads together. My broadband connections bandwidth was not used optimally by Windows 10 it seemed.
Windows Update process was also slow.
3. I updated Samsung Magician 4.6 manually (for my SSD)
4. I noticed that audio output was very less. I have to put volume to 100% to get the same level I would get at 30-40% with Windows 7.
Then I noticed that Windows Update was able to find a RealTek driver for me. I thought 'lucky me' and updated that (again slow process).
After a reboot, I can barely hear the audio. So, the drivers are definitely not working properly.
The output from headphones is just normal though. I am not sure why the speaker output has gone down so drastically.
Not used the system much, but it does seem to be slower than Windows 7.
