Brightness Issue after creators update.

Okay so I have noticed that when I go into a game such as Resident Evil 7 full screen or Dark souls 3 and some other games into full screen mode the game will get really bright or when I exit back to desktop it will be really bright. However if I run a game in borderless windowed it will keep my current brightness settings. Now this doesn't happen to all of my games in full screen mode, but I have noticed a number of them starting to do this more.

I use the Nvidia control panel to adjust my Desktops brightness settings, usually when this happens I go into the control panel and click on and off my color settings. Apparently on the Nvida forums I'm not the only experiencing this too.
My GPU is a Gigabyte GTX 970 G1.

Is anyone else getting this too here?

Here are some fixes suggested by Microsoft Support. The 1st method worked for me.
I was a bit skeptical for the 1st one, since uninstalling anything is a bit scary, but it worked. Hope it helps you too.

Method1: This circumstance can occur if the device hardware fails or if the device driver fails.
Please follow the below steps and see if it helps,
1. Go to Run by typing Windows + R simultaneously and then type devmgmt.msc to go to device manager.
2. Select Display drivers right click on it and select uninstall and click ok.
3. Right-click your computer name in Device Manager and click Scan for hardware changes. Device manager scans your system and automatically reinstalls your device.
4. Right-click the device and click Properties. On the General tab of the device Properties dialog box, in Device status, you should see the message This device is working properly.

Method 2:If issue persist suggest him to visit manufacturer's and download latest display driver and install in compatibility mode.
Follow the steps below on how to install driver in compatibility mode:
1. Download the driver from the manufacturer’s website and save it on your local disk.
2. Right click on the setup file of the driver and select “Properties”.
3. Select “Compatibility” Tab.
4. Place a check mark next to “Run this program in Compatibility mode” and select operating system from the drop down list.
5. Let the driver install and then check the functionality.

Uninstalling Nvidia's driver from device manager is not a good thing to do, if you do that you could risk errors and corruption, if you uninstall it's recommended to do it from control panel.

As for the latest drivers unfortunately people in Nvidia's forums have been reporting issues from thier latest drivers and it would be best to wait for a newer driver to be released.

I have a possibly related issue: The brightness control on my laptop no longer functions properly. At the lowest, it dims to unreadable. Moving it up just a notch goes to full brightness. Moving it further makes no change until about midway through the range it dims slightly and then at the very top it DIMs about 50%. Have tried every permutation of driver/uninstall/version without success...

For some weird reason, disabling write combining (USWC) did the trick for me. Now ICC profiles are fine after exitting games.

Where is write combining located?

False alarm. I rechecked with uswc on and it's still fixed. Maybe it was a Steam glitch that was corrected. Write combining is faster on and there is no easy way for toggling in ON/OFF so leave it alone for now.

I have been on the Nvidia forum looking, and it would appear there are BIG issues with Win 10 CU & Nvidia drivers. As for me, outputting to a 4k TV via HDMI 2.0, before CU everything was fine. After, my display is VERY dark to the point of being unusable. There are numerous other issues on their forums, games dropping FPS, crashing, BSOD...don't know if the fault lies with MS, Nvidia or both...
