Compatibility And Older Links
Check what carries over when moving from an older release.
Old Website And Download Links
Existing article and installer addresses on this domain are retained or mapped to a relevant current page. The main download keeps the stable address /FastStartup.exe.
Upgrading From The Previous Release
Close Fast Startup in every Windows session, then run Setup normally from your usual Windows account. Setup now asks for administrator permission and installs in Program Files for all users.
For the supported previous 8.1.0 user installation, Setup verifies the new program files before removing the old installation through your original Windows account. Saved appearance settings and restore records remain in your user profile. Each Windows user keeps separate settings and startup entries.
If Setup cannot safely verify your account or the previous installation, follow its message before retrying. It does not force running applications to close. If removal of the old installation does not finish, Setup reports this and retains the new application and a configuration backup.
Files And Features From Older Releases
The current version manages supported entries for your account. It does not replicate every historical startup location or change the Windows power feature called Fast Startup. Older tutorial URLs continue to explain the supported workflow.
Light, Dark And Saved Settings
A new profile starts in dark mode. You can switch to light mode, and your choice is remembered. Upgrading keeps your saved theme and eligible restore records.
Windows Requirements
Use 64-bit Windows 10 version 1809 or later, or Windows 11. The app uses the compatible .NET Framework included with these Windows versions. Administrator permission is needed for installation, while normal app use runs with your own account.
