What is Start.exe?

The genuine Start.exe file is a software component of Sandboxie  by Invincea.
Sandboxie is a sandbox-based isolation application. Start.exe launches the Sandboxie program. This is not an essential Windows process and can be disabled if known to create problems. Sandboxie creates a virtual sandbox (an isolated environment in which applications can operate without permanently modifying the local drive). Sandboxie can be used to safely test untrusted programs or for surfing the Internet. The program was originally authored by Ronen Tzur. Sandboxie supports the Windows platform. Invincea is an American company that develops security solutions for digital data. The company was founded in 2006 by Anup Ghosh with major investments from major firms such as Dell Ventures, New Atlantic Ventures, and Grotech Ventures. Invincea is currently headquartered in Fairfax, Virginia, USA.

Best practices for resolving Start issues

A clean and tidy computer is the key requirement for avoiding problems with Start. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the Start.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
