problems with windows 10 and google chrome

since loading windows 10 i have seen a number of frustrating issues when using google chrome which i have never had before. The most frustrating of these (i have a touch screen laptop) is if i drag the cursor over the screen it resizes either larger or
smaller which is not what i want. Not a techie so whilst i have tried to fix it looking at other issues i have still not been successful - any ideas how i can fix this please?

 

upgraded to windows 10 big big big problems

hi i upgraded to windows 10 about a week age {big mistake} it was a bit like little red riding hood syndrome got the reminder to up grade from windows 7 to windows 10 ALL YOUR FILES WILL REMAIN RIGHT WHERE YOU LEFT THEM but they didn't and i am really stuck
i am a builder not a computer programmer and i now was left looking at a blank screen which after upgrading, i managed to find out that my laptop had to be plugged into an external screen to allow me to get it back running which i did that problem solved.
next issue was home screen is missing all my old shortcuts not a big problem as i will try put them back on when i have time. my biggest and most FRUSTRATING PROBLEM lies with not been able to access all my word documents when i bought the laptop i had to
buy word document separate which i did

now its gone when i open a document i just get a heap of symbols. i cant do this in my business sell something {word starter 2010, word documents}and then take it away when a newer version comes out.

i am really upset and frustrated with this i have tried to recover this but cant and have been locked out of my business laptop for over a week now with customers needing information and other work needing doing

sorry about the rant but help help please

 

Sounds like you got yourself on a non administrator account does it ask for a password when you try to install a program or delete program.

 

No i'm on admin account it dont ask for password when i try to install a program it says a error because it can't write to registery! but i just wanna reinstall to factory settings but i did everything i could think of

Windows 10 installation cd
Windows 10 installation usb
Systemrestore
...

But everything fails

Thanks for your time !

 

So you cannot clean install from USB or DVD during boot-up?

 

i solved it ! The only solution whas to put the hdd in another computer as a second hdd and format it.

 

Probably the safest way. We'll never know now, but my guess is that some malware had blocked access to the registry. A format would have wiped that clean.
