Step 2: Delete residual files

  • Press Win + R, type %ProgramData%\Stardock, and delete the WindowBlinds folder.
  • Navigate to %LocalAppData%\Stardock and delete any WindowBlinds-related folders.
  • Manually check C:\Program Files (x86)\Stardock\WindowBlinds – delete if still present.

Step 3: Clean the registry (optional but recommended)

  • Run regedit as administrator.
  • Navigate to HKEY_CURRENT_USER\Software\Stardock\WindowBlinds – delete the key.

  2. Look for wblind64.dll. If it is missing or has a size of 0 KB, proceed.
  3. Navigate to C:\Program Files (x86)\Stardock\WindowBlinds\
  4. Copy wblind64.dll from the install folder.
  5. Paste it into C:\Windows\SysWOW64\ (you will need admin permission).
  6. Open Command Prompt as Admin and run: regsvr32 C:\Windows\SysWOW64\wblind64.dll
  7. Reboot.
