I am running Windows 7.0 on my PC and quite like it but I have got 2 issues with my PC. On start up I get an error message about a file missing and I have a spyware file I cant get rid off. When I bought my PC i didnt get a Windows 7 CD otherwise I could do a fresh install and sort out these issues. My question is, if I buy a Windows 8.1 CD and do the upgrade is it like doing a fresh install and it will remove these 2 problems or is it more like an upgrade and these problems will remain.

If you're installing a new windows I'd recommend you do a Fresh install every time.

How about some more details about the PC? Does it have a name and model number?

So when you start the install it gives you the option off fresh install or upgrading.

That depends what version you've bought.

I would not consider that an upgrade. In my opinion, win 7 is their best OS yet. Why not take the computer to a computer professional and see if they can fix your problem?

Download hitman pro its free for 1 month, after that month it will still scan but not remove malware.

P.S. What is the name of the file that is missing?

After posting the original post I thought to myself why do I want to spend 5000 Baht on Windows 8.1 when I prefer Windows 7.0. Gates has got enough money, its silly making him even richer if you can help it. I spent an hour reading up on the internet about the issues my PC had and have now resolved them. Happy Days.

I wouldn't be running 8 (8.1) on my laptop even though it shipped with it except that it won't run on 7. I tried it. Toshiba didn't make 7 drivers for this newer laptop and I learned that the hard way by not checking first. I had to revert (format and reinstall) to 8 to have all of the drivers I needed.

7 will be around a long time, I believe. XP was so much more stable than 98 because it did a CRC on every OS file as it booted and replaced them if needed from a cache. No more formatting and reinstalling every 6 months. XP hung around for 12 years and is still on many computers.

But 7 is so much better. Now if they'd just put the backup imaging scheduler back on 8 like it is on 7 and dump the crazy new backup, I might start to like 8.

Win 8 is the best yet apart from the horrid interface - easily fixed with free tools like Classic Shell.

If you do not want to shell out for Win 8.1 then why not download an official copy of Win 7 and burn to DVD. You can then try to repair your installation.

Ref the 'spyware file' if it cannot be removed by the usualMalwarebytes/Superantispyware/hitmanPro/Bitdefender then post its name. Maybe some more specialised remover is required.
