you probably just need to reboot your PC...
I just did a test last night (upgrade and rollback to Winows 7), everything is fine.
I would do a clean install of Windows 10 instead of the upgrade install and see if that fixes your problem. If not future builds may fix them. You have until October to decide if it's worth keeping or not.
Upgrading would create a crazy size restore point
Eh up... took the tip given earlier about linux... the upgrade win 10 was not stable due to my computers missing files, very wobbly and programmes would not load.. so now the old lenovo is now operating on ubantu 14.4 which is every bit as good as win7 for all the things I want it to do.. in some cases its much much faster others not so.. but all in all for a FREE OS its really something to write home about, have also read... that it was considered the most secure system according to some peeps who have something to do with GCHQ security.
I have talked with MS about this and its a dead end.. end of the day I should have made sure I had the rescue disks instead of assuming I would know where they are as it was over 3 years ago the lenovo's keyboard gave up. So I will wait a few more weeks and see if I really want win 7 back.
I among with many others were the one most disgruntled with windows8.. the update from 8 to 8.1 was always problematic and often resulted in BSOD's.. in efforts to find a fix I was forced into areas I never would have gone, read and read the most mundane, long winded explanations and tried the solutions offered always in the end reverting back to win8.
Funny thing is that once I got my lenovo going and win7 started.. I knew my win8 was faster and more slicker on my toshiba laptop which is more or less same specs as the lenny except for the AMD.. win8 beats win7 and ubantu 14.4 imho and I never ever thought I would say that..
So now my time with win10 is done, the rollback wrecked my computer which if I had had the sense to back up with new disks instead of thinking I could find the old ones was my mistake, but to be honest I like to face danger head on hence why I updated me perfectly working win7 lappo with new keyboard on Friday da 13th LOL and paid the price for assuming and playing about..
Ubantu 14.4 though is the silver lining and its strange not having to have an anti virus, but as they say.. the biggest threat to a computer usually lies between the computer and the chair LMAO.
The factory OEM key is blacklisted for a reason. OEM PC's with Windows 7 pre installed use a common key to that manufacturer. That same key will be used on every Lenovo with that version of Windows 7 installed on it. Those PC's do not activate online, they activate against a SLIC table in the BIOS. That code is blocked so you can't read it out and try to use it on another PC. If you use anything other than the custom OEM install disks that key is useless. The code on the sticker is there so if need be, you can install Windows 7 with normal install media. You will most likely have to activate online, I have had to do it that way any time I used one of those codes on the OEM sticker. That being said, I have yet to have any issues activating it that way. It's all automated with voice recognition etc. The tricky part is getting clean unmodified ISO's for Windows 7. It seems a lot of the links like digital river, have gone dead. Right about the time mainstream support ended? If you order a set of recovery media from Lenovo, it should install and use the factory OEM key just like it did when you bought it. Recovery media should be cheaper than buying a full version of Windows 7. If they still offer it that is.
Just want to say that I haven't had any issues installing Skype for desktop, or anything else.
Even my old Tomb Raider games work.
My only real problems have come because it keep updating drivers that I don't want to change.
Every time it updates my sound quits working.
Try creating a bootable install disk for Windows 10 and just start from scratch.
I'm not sure what will happen when Windows 10 goes live some computers that I have bought in the past have come with 2 registration numbers, one from the manufacturer and a sticker with a Microsoft one you can use too reinstall.
The last 3 computers that I've gotten have come with Windows install disks.
I'm not sure that anyone knows exactly how the whole process is going to work yet.
My two laptops that have embedded windows 8 keys, have stickers that just say Windows 8. There is no second product code on a COA sticker. It's not needed. Official Microsoft install media will read the embedded key and use it automatically. OEM provided install media will too. If you buy the OS separately, by itself, you'll obviously get a code with it. How Microsoft does the free upgrade to 10 is anybody's guess.
There does seem to be this - it requires a product key though so not sure if it will work with the one the OP has - it may just work for retail keys (not OEM ones) by the look of it.
Microsoft Software Recovery
I tried 3 different Windows 7 product codes and non of them worked. Two TechNet keys that are Retail and one OEM key for an OEM version I bought online. There was a thread on that download and I don't think anybody got it to work. Can't hurt to try it though.
I have tried 5 Ultimate keys and all were declined. I thought maybe the system needs IE instead of Firefox so I tried that. Same results except one key was in the wrong language (English). The system is an outrage as I know my keys are retail and valid. Anyone looking to download from that site is going to end up disappointed and probably that is the idea so they buy an 8.1 key.
Someone needs to do something about making that site work.
