i was prompted by my laptop yesterday to perform a windows update...i did so, then restarted the computer to affect the changes.....ever since then, my laptop fails to boot up, using normal, safe, and any other mode that exists. i get a blue screen of death that contains the file win32k.exe, but am unable to log in far enough to find and delete this suspect file. any suggestions?

Win32k.exe is very suspicious. Windows uses a very important file called win32k.SYS, not EXE!
Message comes up saying "error" then giving the Win32k.sys as the problem.

Best practices for resolving win32k issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active win32k process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the win32k.exe on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
