Once my firewall told me that system process is accessing some ip location via protocol 41 . So I made IP search to know the receipient of this information . It was pointing to microsoft usa . I blocked it. Again it gave another message now the IP address was changed a bit now it was microsoft UK . So I blocked it . This way it tried 4 -5 times. Then on next boot it restarted the boot . After it gives message that windows has recovered from a serious error Do you want to send error report. on selecting no this message comes again . Only way to stop this is drag it to a corner of window

Best practices for resolving dwwin issues

A clean and tidy computer is the key requirement for avoiding problems with dwwin. 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 doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
