Edge is really an application made for tablets, I think its why is struggles so much.
I have upgraded to Win10 with no issues, but you have to follow certain steps.
FIRST... BACKUP ALL IMPORTANT DATA TO AN EXTERNAL SOURCE!
If you are using Win 8/8.1 then it should upgrade without a problem, and should actually run better. But do not do the automatic upgrade through Microsoft. Download the upgrade to a USB drive and run it from there. If it asks you to check and install updates first, I recommend skipping this stel. Once you upgrade Win 8/8.1 you will have 30 days to revert back if you don't like, and you may not be able to revert it back correctly without some tools. Win10 is much better than Win8, you just need to make sure its installed properly.
On Win 7, make sure your copy is valid, and check the specs to make sure your laptop will upgrade properly. Not all Windows 7 machines meet the upgrade criteria.
You cannot upgrade XP or Vista for free. If you need these upgraded, just buy a new laptop and save yourself the headache!
Once you upgrade
