I know a few people that had major problems. One friend rolled back, and that didn't work either, he had to do a factory recovery.

I suffered only one major issue. I had to redo my entire network due to some services being turned off by default, services needed for networking.

I'm sure this was connected with MS removing Homegroup.

Oh, and Windows told me that things like Speccy, CCleaner, CPUZ, and GPUZ would no longer be available, but they still work.

Updated my lappy...and Edge no longer works.

Par of the course for 10 ....

I wouldn't use Edge anyway, but I'll give it a try. I did notice that MS decided to put a shortcut to Edge on my desktop.   

Edge working fine here. Well, as good as it ever did.

So... no loss in daily driver functionality than? 

So far so good on my personal PC & roughly a dozen work PCs on my end.

For me when it tried to upload it the upload failed ( 4 times )

So I guess lucky me   

Only thing I've noticed so far is that it reset all my icons (as in IconPackager) to system default even though IconPackager thought my theme was still loaded.  That actually makes sense I think.  Applying a different IP theme took care of it.

I'm sure there's more lurking around in there that I just haven't noticed (and may never notice).

i don't have major problems. just some quirky minor stuff. wonder if patch tuesday will fix any of those.

Hah! I am still running the original version of Windows 10, every time I try to update it a failure occurs. It says the system reserve partition is too small or something.   

Nope...my REAL MACHINE is still running 7 just fine...

My only peev was that it took four hours from start to finish. The update also did what I expected it to do. Reset all my icons to those butt fugly yellow ones. Resetting the icons though took care of that.

gpedit.msc is your friend.

And, though it goes without saying, "Welcome back, Doc!!"

1. Lost all settings in my user profiles after updating. 1st time something so bad happened to me with a new release or even insider builds

2. Lost my Logitech mouse and keyboard and other usb devices as windows standard drivers for USB where installed and failed after update.

Before Microsoft going batsh*t insane, installing a new version of Windows always had the potential to go very wrong.

The difference is: then we only had to worry about it every 3-4 years and only when we were ready, now it's every 6 months whether we like it or not.

I compare Windows 10 to that crazy gf that always makes you feel like you are walking on egg-shells: she can blow up on you at any moment without warning. You are not given any time to adapt (it's impossible anyway) and your anxiety levels go through the roof - until you dump the crazy b****.
