❌ [Error] Lock screen wallpaper unchangeable

[Luximoz]

❌ Error report

Describe the error

• So, I tried WinPaletter's latest version again after months of not using it, and I noticed it broke the accent color and the colorization color on my 1809 setup (both values were no longer synced at Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM, they should be synced except for the transparency values where AccentColor is at FF (fully opaque) and ColorizationColor's transparency can be anything), resulting in my window borders having different colours from the taskbar (I'm using StartIsBack++), it also resulted in StartIsBack++ having a purple color in the start menu, so I decided to use a System Restore point before I gave WinPaletter another try and now, the lock screen can no longer be changed via Winaero Tweaker no matter if I revert the wallpaper to the default one and then try to get a custom one back.

How to reproduce the error

• Have a custom lock wallpaper set by Winaero Tweaker prior to WinPaletter's installation and then setup a System Restore point, then install WinPaletter, and revert to the System Restore point

Screenshots/Screen records

I didn't take any screenshots prior to using System Restore because I thought I would have reverted all of the issues I was facing

1: Titlebar and border color

• Modifying HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Accent : AccentColorMenu with a color different from HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\DWM : AccentColor in Windows 10 results in borders having different color from titlebar, and I was about to create a new color entry in Windows 10 till I discovered that it is a bug; shutting down (not restarting) Windows and reopening it will re-synchronize both colors, and so I reverted this color entry.
• I am unsure if StartIsBack++ should modify these 2 registry keys. WinPaletter modifies both keys by the same color:

EditReg(TreeView, @"HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Accent", "AccentColorMenu", Titlebar_Active.Reverse().ToArgb());
EditReg(TreeView, @"HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\DWM", "AccentColor", Titlebar_Active.Reverse().ToArgb());

This is a code snippet of what WinPaletter does.

• To fix this issue, try setting another color in Windows Settings.
• If this didn't help: delete the values (not keys) AccentColor and AccentColorMenu in registry, shutdown your Windows then reopen it.
• Let me know if these steps don't help you.

2: Lock screen image

• WinPaletter doesn't modify lock screen image for Windows 10. It only modify preferences\tweaks.
• Delete registry value LockScreenImage in key HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization
• Try not to use Winaero Tweaker to change lock screen. Try the following steps:
  1. Open Windows Settings and go to lock screen settings
  2. Use a different method for lock screen like Windows Spotlight, or try another image.
  3. Lock your Windows or sign out
