Before running an EXE or extracting a ZIP, compare its SHA-256 hash with the published value for the exact filename and version. Checksum lists: Blue Wave 2.1.0 · Weather 1.1.6 · Notepad 1.3.0 (portable and setup) · Time Core 2.3.0.

1. Open the folder containing your completed download in File Explorer. Right-click an empty area and select Open in Terminal, then use a Windows PowerShell tab. Administrator access is not needed.
2. Run this command, replacing the quoted filename with the exact name of your downloaded file:
   Get-FileHash -Algorithm SHA256 -LiteralPath ".\HBOMB.Blue.Wave.2.1.0.exe" | Select-Object -ExpandProperty Hash
3. Compare all 64 characters with the checksum beside that filename in the list above. Uppercase and lowercase letters are equivalent. For Weather, check the downloaded ZIP before extracting it. Notepad's installer and portable EXE have different hashes.
4. If the hashes differ, do not run or extract the file. Download it again from the app's official link. If it still differs, report the filename and version.

A matching checksum confirms that your download matches the published file. It does not prove the app is safe, identify its publisher through a digital signature, or replace code signing. Keep Windows security protections enabled.

1. Quit older Blue Wave copies from their system tray menu, and close other live wallpaper apps.
2. Save HBOMB.Blue.Wave.2.1.0.exe in a folder you want to keep, then double-click it. No installation is required.
3. If the controls are hidden, press Ctrl+Alt+H or use Blue Wave's tray menu. Keep any MP4 wallpaper you select in its original location.

1. If upgrading, quit Time Core from its tray menu first. Open HBOMB.Time.Core.Setup.2.3.0.exe from your Downloads folder (or your chosen save location).
2. Follow the setup prompts and wait for installation to finish.
3. Open Time Core from the Start menu after setup completes.

1. Right-click HBOMB-Weather-1.1.6-Portable.zip, choose Extract All, and extract the entire archive to a folder you want to keep.
2. Open the extracted folder and double-click HBOMB Weather.exe. Do not run it from inside the ZIP.
3. Keep the resources and weather-assets folders alongside the executable. Move the whole extracted folder together if you relocate the app.

1. Open HBOMB.Notepad.Setup.1.3.0.exe from your Downloads folder (or your chosen save location).
2. Follow the setup prompts and wait for installation to finish.
3. Open HBOMB Notepad from the Start menu after setup completes.

• Download incomplete or file will not open? Check your browser's download list and available disk space. If the download failed, retry using the app's Download button above.
• Weather reports missing files or assets? Extract the entire ZIP again into a new folder and run the app from there, with both resource folders beside it.
• Windows shows a security warning or blocks the app? Stop and read the exact message. SmartScreen and Smart App Control assess apps and downloads; a warning should not be assumed harmless. Keep Windows security protections enabled. Do not add antivirus exclusions or bypass the block. Record the app version and warning text for a bug report; on a managed PC, ask your administrator.
• Still unable to start? Close the app, restart Windows, and try again. Record your Windows version (press Win+R, type winver, then press Enter), app version, and exact error message when requesting help. Remove personal information from screenshots.
