Internet issues after Windows 10 Anniversary Update

He did the reinstall without affecting most of my files, only lost some apps.

Some websites work ok most of the time, other times they only partially load.

Unsure about OEM drivers as it came with Windows 8.

Not synching with anything else.

I just spoke with Asus tech, and they don't supply their machines with product key, so I would have to send it to them to do a factory reinstall of Windows 8, or buy it.

Create Bootable USB Flash Drive to Install Windows 10 Installation Upgrade Tutorials

Hi, if you don't already have a bootable win 10 medium then follow the above.

Then follow the tutorial you posted. As part of the process you will delete all the (4 if UEFI) partitions comprising Win 10.

Note that if your existing Windows build is 1703 (Creator's) then the one you will install is 1709 (the Fall Creator's build).

We strongly urge and advise all users to routinely use disk imaging e.g. Macrium Reflect (free) so that if something goes wrong- even a disk failing- you can restore a previously created disk image of Windows (or any data partition or disk) and have your PC running as it was when you created the image.

This can eliminate the need to do a clean install in many cases and give you a second chance.

 

You still here, DAL? Or anyone? When I am doing this - reinstalling windows. Is there anything specific I should be careful with? Do people do their own reinstalls then come back here with the same issues. Just want to make sure I do not mess EVERYTHING up *Smile It seems fairly easy. But, I do not know what I am doing. However, I am amazing at following instructions as they are written 100% of the time, the first time. Just want to make sure there are no frequent mistakes I could make.

 

Another thought, looking at this it seems like this is an "update". I want to completely remove (or as closely as possible) remove everything on my computer then start from the beginning. This is the best method to do so, correct? I just started and it seems like it is more an "update" but I am only a few minutes in. I will keep reading all the provided information as well.

 

If you follow Dalchina's instructions, particularly deleting all of the partitions, DL the ISO and create your media, then follow the Clean Install....you should be just fine. They are written well.
