I isolated NWIZ.exe as causing a problem in photoshop not opening png files and causing sketchup layout crashes when updating documents.
This is a part of the nVidia GeForce driver and is required. If you have a geForce card DO NOT DELETE IT else Windows will DIE because of it.

People don't seem to understand that a virus can be installed by deleting the NVIDIA nwiz.exe which is safe and then writing itself in the same place and call itself "nwiz.exe" and then when windows starts next time the bad "nwiz.exe" runs instead of the safe nwiz.exe.So if you have the bad copy then yes its bad.

Nwiz.exe is part of the N-Video adapters and allows me to rotate my rotable monitor, I need it and love this feature as part of capabilities of video display adapters using the NVIDIA engine

Found nwiz in System32 files, size 1,583k. At 11:22am today, my CPU usage hit 100% and the HardDrive light was constantly on. I checked the file details and it said it was modified, you guessed it, at 11:22, 08/03/2012. Deleted it and the HardDrive stopped and CPU usage went back down to 3%. If you find it and its as big as mine was...KILL IT!
It caused a problem with MS Excel. Excel would open but then nothing would work. None of the buttons in the menu setup.

Best practices for resolving nwiz issues

A clean and tidy computer is the key requirement for avoiding problems with nwiz. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the nwiz.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
