How to check a Windows installer SHA-256 checksum
Compare a downloaded Windows installer with its published SHA-256 checksum, then check compatibility and publisher information before installing.
Start from the product and receipt pages
Use the official product page to check the release name, Windows version, processor architecture and installer size. Keep the receipt private: a receipt or download URL can grant access to your purchase. A filename alone does not show where the file came from or whether it is complete.
Calculate SHA-256 locally
Open PowerShell and use Get-FileHash -LiteralPath followed by the quoted full path to your downloaded file, then -Algorithm SHA256. This reads the file and calculates a digest; it does not run the installer. Replace the example path with the actual installer location and compare the complete result with the checksum on the official release page.
Interpret the comparison correctly
Matching digests indicate that the downloaded bytes match the referenced file. They do not prove that the publisher is trustworthy or that the program is safe. Obtain the expected digest from the official HTTPS website, not an unrelated copy posted alongside an unknown download. If it differs, stop and contact support.
Check the Windows requirements and publisher
In Windows Settings, System then About shows operating-system and device information. Compare it with the app requirements rather than assuming all Windows devices use the same architecture. Review the installer publisher against the release page. If Windows blocks the file or the publisher differs, stop and ask support; do not disable security protections.
Keep a recoverable first-run example
Before importing a large document library, try a copy of a small representative file. Save and reopen the result, inspect an export, and keep your originals. Store the installer and receipt securely for future reference. IndepApps publishes availability separately from preparation notes; this guide does not mean every candidate is available to download.
