Most of the time the blame for these problems will be on your ISP side.

...but just in case do:

In router, allow access to all of your Internet devices and block all others.

Check your model...

Just another pretty face with outstanding graphics and very poor driving model..

Will do great among arcade racers I'm sure

Could not wait for WU to offer the upgrade. Downloaded the latest ISO and installed from USB. Glad to report all is fine now.

Win10 activated inmediately and updated to latest build (10586.318),...

It seems so, that's why 10 didn't activate as previous OS version didn't match it's key

I'd like to download the ISO image too..

Well, I went ahead and upgraded to 8.1 with the option DVD. OS is activated and this is the result for ShowKey

81076

Looks good in my opinion. Will wait a week or so to be offered the upgrade...

Nope not there, nor it is mentioned in the documentation, not even in the DVD upgrade to Win 8.1 that came with it, which I never did.

Nope, no sticker, but Windows says it is activated. Maybe Superfly will chime in and give some advice..

Cheers

I did restore laptop to its original Win7 Pro from a recovery partition and it is activated. ShowKey displays this

80977

I would think that my best bet now, is to download an ISO image of Win...

Will let you know when done..

Thank you much for all your help

Ok, may go that way. I already have a USB with recover options made for Desktop. Can I use it to recover in laptop?.

Version in Desktop is 1511 build 10586.316, version in laptop is 10.0...

Running ShowKey gets me a "File System Error (-1073741819)" message.

Daughter says someone recommended to delete OldWindows folder to recuperate space on HD, so she did.

Does this means to reinstall Win 8.1?

Thanks in advance

I have a Desktop PC which I upgraded to Win10 with no problems. I also have a Laptop, HP ProBook which was also offered to upgrade to 10 which I did and gave to my daughter.

She attends University...
