How do I reset preferences in Windows 8?

Adjustments I make to images will not stick. I read that this might be because I need to rest my preferences. I can only find a lesson for how to do this for Windows 7 or XP. I have Windows 8 and the directions do not apply as the path does not lead to the folders I need.
Thanks

I'm using CS5.
I'm worried about deleting preferences by using the shift+Alt+Ctrl method because the tutorial lady said it can cause things like keyboard shortcuts to disappear too. I'm not sure if I need to delete preferences or not now.
So my problem is that I have illustrations, line drawings of artifacts, stone tools to be precise. The images look too light and I want to darken the lines. These images are saved as JPEG files. I tried using the brightness/contrast option inder image tab and in the preview it darkens and looks really good, but when I press ok to save the change it reverts back to the original image. I have made sure to make a duplicate copy of the layer and that the original is turned off, but still no luck. I don't really understand the difference between the different modes and channels but changing those did not make a difference. I did find since posting my question that if I try to make the adjustments on a TIF instead of JPEG then it works. So I've converting all of my files to TIF. Kind of tedious though.
Thanks for the reply.

How can I reset preferences on my desktop file arrangement? I cannot change it using the prescribed way.

I am running OS 10.5.8. Recntly I have been unable to set the arrange preferences on my desktop icons to anyhting but by "name". I can select the other options but it always returns arranged alphabetically by name.

If you have the B&W G3 mini-tower, it has an ATAPI interface for the optical drive on the motherboard. If someone has installed a SCSI CD-ROM drive in it, it would have to be connected to a SCSI controller PCI card. If you don't mind investing about $30-$35 in the computer, replace the CD-ROM drive with an ATAPI Pioneer DVD±RW drive in the optical drive bay. Because it isn't Mac-specific, it can be purchased anywhere - including PC stores. I recommend a Pioneer drive because it tends to be more compatible with Macs, in terms of booting to the "C" key at startup. Set the jumper on the back of the drive to Master (factory default is typically Cable Select). The B&W G3 doesn't support the Startup Manager feature, so the Option key doesn't function for that purpose. Additionally, the B&W G3s don't support FireWire booting. If you have an alternate (supported) bootable source, it's best to use the 4-key combination at startup: Command + Option + Shift + Delete to select it. The CD versions of Tiger look the same as the DVDs (black disk with silver X across it) and aren't grey restore disks. The CD versions of Tiger are more scarce, so the price for them is quite high. The same has become true for the Tiger universal installer DVD.

Hi,
iChat (it would help to know which version) can accept Apple IDs as valid AIM Screen Names.
However if you have iChat 5 or earlier you cannot use ones ending in @me.com or @icloud.com issued by iCloud. (they can be used in iChat 6 or Messages as these versions make a double login to AIM and Apple to allow the use of the password).
In addition if you are using an Apple ID for an AIM Screen Name the password still needs to keep to the 16 character limit that AIM has.
AN @mac.com name can be used on any version of iChat (Until the 30th June 2014)
As it does not need a double check with Apple you can use it to log in to the AIM Web pages
Login here with an AIM Name registered at AIM or and @mac.com name and see if you get any suspended account messages.
Sometimes account can be suspended. Usually because something has triggered the "Unusual Activity" item.
About a year ago many @mac.com users that travelled out of their own country found themselves suspended when they got home.
If the Name checks out of if an Apple ID the password in known to be 16 characters or Less then do this:-
In Lion upwards open a Finder Window and use the Go Menu whilst holding down the ALT key.
Select the Library that appears in the menu list.
Navigate to Preferences.
(If you have version earlier than Lion the just navigate to ~/Library/Preferences (that's the Library in you Home - Little House icon - folder)
Fnd com.apple.ichat.aim.plist (even if you are using Messages)
Drag the file to the Trash and Restart the app.

Without your printer model numbers, readers can only give you vague general directions.
System Preferences > Print&Fax > ...
... shows a list of all set-up printers.
If you are having serious problems, it makes sense to "Reset the Printing System" (which also removes all printer set-ups) and add back each printer. It only takes a few minutes.

I recently had some repairs done to my ATT U-verse connection, and now my Safari doesn't open in a full screen. How do I reset that to open in full screen?

I recently had some repairs done to my ATT U-verse connection, and now my Safari doesn't open in a full screen. How do I reset that to open in full screen?

Mountain Lion is set up to close windows when you quit a program instead of saving them. To change this, put Safari in full-screen mode, move the cursor to the top, open Safari menu while holding Option key and close Safari from the menu.
If you want to do it automatically with all programmes, open System Preferences > General, and deactivate "Close windows when quitting an application"

How do I reset iChat and Facetime on an Air so I can basically start fresh?

How do I reset iChat and Facetime on my Air. When I bought it we had everything on my husbands MacBook put on the Air. All the iChat and Facetime setting are his so the Air and MacBook won't iChat or Facetime with each other.

Remove their preference files in the /Home/Library/Preferences/ folder. Remove any related folder in /Home/Library/Applications Support/ folder. Relaunch each application and reconfigure.
Check the rest of the computer for other inconsistencies. For example, the Computer Name in Sharing preferences may need to be changed. Settings in Accounts preferences for the long name, account name, and password. Changing the account name is quite complicated.
If you truly wish to start fresh then erase the drive and reinstall from scratch.

ICloud accidentally set-up with erroneous email acct. How do I reset the email originally used to start the Apple ID? I'm stuck in a loop...

Hi Apple friends! Here's my frustrating situation. When I got the new computer (2012 Macbook Pro), I tried to set up iCloud but accidentally input an erroneous email acct. I cannot access iClod because the email was accidentally input as "[email protected]", not "[email protected]". How do I reset the email originally used to start the Apple ID? I'm stuck in a loop, and not only cannot use iCloud, but I keep getting messages popping up to register my iCloud with a non-existent email...
Help?
Sincerely,
Cole
[email protected]

Have you tried to go into System Preferences > iCloud and entering the correct information there? You will first have to "sign out" of the wrong account and then log in with the correct information.
If that does not work you should direct follow up to the iCloud for Mac forum.

I am English but live in Spain, When I got my new Macbook Pro I set the language to English, so far so good. Then I stupidly set the keyboard to British when it is obviously a Spanish keyboard. How can I reset it to Spanish. Sorry cant find question mark

LizMaddock,
you can reset the input source to Spanish by selecting the Keyboard pane of System Preferences, selecting the Input Sources tab, and pressing the “+” button in the lower-left corner to select one of the Spanish input sources. The “Spanish – ISO” input source is most similar to the physical Spanish keyboard layout.
