Local account:

• You use a user name (and password if you want one) to sign in to Windows 8 just like it was in Vista and Windows 7.

• When you sign in with a Microsoft account, your PC is connected to the cloud.
• Your friends’ contact info and statuses are automatically up to date from your Hotmail, Facebook, Twitter, LinkedIn, and other accounts.
• You can get to and share your photos, documents, and other files from SkyDrive, Facebook, Flickr, and other accounts without signing in to each one.

• You can get apps in the Windows Store and use them on any PC running Windows 8 that you sign in to.
• Easily reacquire your Metro style apps on multiple Windows 8 PCs. The app’s settings and last-used state persist across all your Windows 8 PCs.
• You can associate the most commonly used Windows settings to your user account. In this way, the saved settings are available when you sign in to your account on any Windows 8 PC. So your PC will be set up just the way you are used to.
• You can also save time with sign-in credentials, because now the same credentials are available for the different apps and websites you use and you can easily get back into them without having to enter credentials every time.

​

​

26. If there's nothing in them that you would like to copy back into Windows 8 from the C:\Windows.old folder, then you could use Disk Cleanup to delete the Previous Windows installation(s), Temporary Windows installation files, and Windows upgrade log files items to free up the large amount HDD space that they take. (see screenshots below)
NOTE: This step will delete C:\$Windows.~BT and the C:\Windows.old folder from step 25 above.

​

​

​

​

27. It is highly recommened that you create a password reset disk for your user account just in case you forget it later. You will be able to use it to reset your user account password.

That's it,
Shawn

You're most welcome ummagumma.

Another vitally important point is to UPDATE YOUR BIOS AND DRIVERS for Win7 prior to trying to upgrading to Win8. My (very tech savvy) friend hung up in the upgrade process simply because his Intel drivers had not been updated in a year. The mobo manufacturer even clearly stated that the newer driver was necessary for Win8 upgrade on the update page. Do yourself a favor and get your drivers ready for the upgrade!
Whew, nice job Brink! I had to read through all the posts to make sure I was not duplicating any other post, and your dedication is outstanding!

When you upgrade to Windows 8 and go into the desktop are any of your Windows 7 desktop icons still available or do you have to put them back onto the Windows 8 desktop, also when I downloaded Windows 8 I forgot to download it as an ISO, and it just downloaded all the files that were in the iso, can you upgrade to Win 8 using those files from the HDD or do you have to install it via usb or DVD.

 

[Brink]

Hell Nugar, and welcome to Eight Forums.

It all depends on if you select the Keep Windows settings, personal files, and apps at step 8 or not for the desktop icons. In addition, it depends if the programs any icons may be for are compatible with Windows 8 and kept. If incompatible programs get removed, then any icon on the desktop for them will be as well. The Windows 8 Upgrade Assistant will let you know if anything is incompatible though.

If you used the "Windows 8 Upgrade Assistant" to download Windows 8, do you still have the Install Windows shortcut on your desktop? If so, then you could just run that shortcut to start upgrading to Windows 8.

If you don't have the shortcut, then the "Windows 8 Upgrade Assistant" stores the Window 8 upgrade installation setup.exe to run in the hidden folder below.

Not sure about this, but if you're upgrading from XP to 8 you will be required to wipe XP, but the installer should still keep al your user info. programs, drivers, etc will have to be reinstalled from scratch. this isnt the case when upgrading from 7 to 8. correct me if i'm wrong, but this is what i've heard.

 

[Brink]

Hello Stephen,

When upgrading from XP (SP3), you only keep user accounts and files.

When upgrading from Windows 7, you keep backup schedule, programs, Windows settings, user accounts and files.

The blue Note box at the top of the tutorial will have more details about this though.

Hope this helps,
Shawn

 

[muiacir]

which one is better?upgrade or simple install?
if we upgrade , our programs that are installed in windows drive or our firefox history and etc will work?

 

[Brink]

Hello muiacir,

It's more of a personal choice, but a clean install usually gives you the best results.

http://www.eightforums.com/tutorials/13375-clean-install-windows-8-upgrade.html

 

[muiacir]

so what is differenet between them and if we upgrade , our programs that are installed in windows drive or our firefox history and etc will work??

 

[Brink]

If you clean install, then you start with a fresh install of Windows 8 without anything from your previous Windows.

If you upgrade, you keep backup schedule, programs, Windows settings, user accounts and files from your previous Windows 7 in Windows 8.

 

[muiacir]

thanks shawn.
i have 2 question
1-as you know if we clean install the windows , all of our program will remove and we should install them again.if i upgrade windows 7 to windows 8 , my programs like firefox office andetc will work correctlly?
2-if our system has incorrect registry or virus , after upgrading will them correct?
3-can we upgrade windows 8 enterprise to again windows 8 enterprise or win 8 professional?

 

[Brink]

You're welcome.

1-as you know if we clean install the windows , all of our program will remove and we should install them again.if i upgrade windows 7 to windows 8 , my programs like firefox office andetc will work correctly?

Yes, it should.​

2-if our system has incorrect registry or virus , after upgrading will them correct?

An upgrade will not help with a virus. The virus will still be there. If you have a virus, then a clean install would usually get rid of it since it formats the hard drive.​

3-can we upgrade windows 8 enterprise to again windows 8 enterprise or win 8 professional?

No. You cannot upgrade to the same or lower edition. You could do a refresh that is close to doing an in-place upgrade with the same edition though.

or

http://www.eightforums.com/tutorials/3610-refresh-windows-8-create-use-custom-recovery-image.html​

 

[muiacir]

thanks.
1-the answer 1 "it should" means the programs will work and do not need install?
2- after upgrading , the past windows(7) will remove?

 

[Brink]

Q1) Yes, if you select the Keep Windows settings, personal files, and apps option at step 8 in the tutorial on the first page. If there are any incompatible programs that will not be carried over into Windows 8, then you will let known at step 9.

Q2) Yes. When the upgrade to Windows 8 is successfully completed, Windows 7 will no longer be installed. Instead, you will have a copy of it in the Windows.old folder as per step 25 that you could delete if you like.

 

[muiacir]

thanks shawn.but do you recommended that i have windows 8 and 7(2 OS) or only have one OS?

 

[Brink]

Since when you purchased the Windows 8 upgrade, you agreed to not to use the product key for that Windows 7 anymore as per the EULA to qualify for the lower priced Windows 8 upgrade.

If you have another Windows 7 product key, then you could use it to dual boot Windows 7 and 8 if you like, but otherwise you would be violating the EULA.

 

[muiacir]

thanks shawn.you helped me so much

 

[Brink]

You're most welcome.

 

[Ex_Brit]

I noticed this today which is useful for those people who were slow and missed the deadline for their Windows 8 previews which are now rebooting every 2 hours. This way, instead of downloading the OS which could feasibly take longer than that 2 hour window, it provides an installer.

Shawn: just realised this should perhaps be in a separate thread, feel free to split if off if you agree.

Hello Peter,

Yeah, it's the same as doing step 4 here to either download/install with a key.
