While the very efficient & effective in-built Windows Troubleshooters are meant to make your life easy, what if they themselves refuse to work properly, some day, for some reason!?
1. See if a System Restore helps you.
2. Click Start >Search Menu Bar >cmd >rt click on result > Run As Administrator > Type sfc /scannow > Hit Enter. This will run the System File Checker. This will examine all your system files and replace them if any are found to have been corrupted. Reboot when asked. Alternatively simply download FixWin and click the Run System File Checker button.
3. Try using the Troubleshooters when logged on as a new Administrator user.
4. If its your online troubleshooters which are failing, try a local troubleshooter. Its possible that there may be issues with the connection to the site where you download the online troubleshooters
5. It could even be an issue with the files being stored in %temp% folder/s. Run Disk Cleanup utility to clear temp and junk files.
6. The troubleshooting reports, logs & other data are saved in the following locations:
- %LocalAppData%\Diagnostics : It contains folders for previously run troubleshooter.
- %LocalAppData%\ElevatedDiagnostics : It contains folders for each troubleshooter which was Run as Administrator.
- Windows Logs/Application
- Applications and Services Logs/ Microsoft/ Windows/ Diagnosis-Scripted/ Admin
- Applications and Services Logs/ Microsoft/ Windows/ Diagnosis-ScriptedDiagnosticsProvider/ Operational
- Applications and Services Logs/ Microsoft/ Windows/ Diagnosis-Scripted/ Operational
See if anything here helps you here.
While this eventuality may never arise, should it, hope some of these general suggestions are of help to someone, someday.
