The genuine sqlwriter.exe file is a software component of Microsoft SQL Server by Microsoft Corporation. The Microsoft SQL Writer Service ("sqlwriter.exe") installs automatically when SQL Server is installed. Although a computer can have multiple instances of SQL Server, of different versions, SQL Writer is a shared service and only present once. Windows Installer always installs the latest binary in "C:\Program Files\Microsoft SQL Server\90\Shared\sqlwriter.exe". This service must be running and should not be removed if the Volume Shadow Copy (or VSS) backup service is in use. (If not using VSS for backup and restore, "sqlwriter.exe" is not needed.) It resolves the conflict that would otherwise occur because of the SQL Database Engine having database files locked with exclusive access when the Windows backup programs want to copy them. It briefly freezes I/O in a given SQL Server Database Engine instance so that data is not backed up or restored while transactions affecting it are incomplete, such as between deleting moved data in one place and writing it in another.
SQLWriter stands for SQL Server VSS Writer

Best practices for resolving sqlwriter issues
A clean and tidy computer is the key requirement for avoiding problems with sqlwriter. 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 executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
To get your computer running as fast as it did on day one, you can 8reset your PC. Your personal files will remain intact, but any programs you installed will need to be reinstalled.
To help you analyze the sqlwriter.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. A good Bantivirus software detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
