Following the instructions/article by Mr Lawrence Abram titled "How to boot Windows 10 by C Prompt" as I could not otherwise boot my PC,I successfully reached the Command prompt stage by following the above suggestions.However,login to normal boot of windows 10 failed and when re-booted/restarted from Command prompt it stopped showing the blank black screen after signing in to my account.I can still invoke restart or shut options through ctrl+Alt+del which will bring the login screen but when signed in to my account it will repeat the above and fails to reboot windows.
Background to the problem
For some unknown reasons,Explorer.exe stopped working and with Programs Icons on the Task Bar including Start,Edge and most others stopped responding when clicked to open.I also recall UAC,profiles also changed. I tried to find solution by reading the suggestions on internet files but failed to repair it.
I remember having made some changes in in Windows/system32 and sysWOW64 where I changed the file extension of the file "ExplorerFramae.dll to BAK" in both the folders and also copied the old file "ExplorerFrame.dll" as before,in both the folders which was done following instructions on net which became necessary as I could not open the Start tab,Search option tab,Microsoft Edge and almost all the links to other programs on task bar including internet and for most of these when clicked to open the error a window popped up showing error "Explorer.exe" in the upper part and" class not registered." in the middle part.So,in nutshell because of these issues, I had to look for a solution on the internet which after trying a few I got attracted by a suggestion to replace/ change file extensions (as stated above) from dll to BAK but also keeping/replacing dll file extension in both the holders.
After doing this change the PC simply failed to boot after sign-up.
Without reboot and windows running,obviously I can not reach the folders "System32' and "SysWOW64" in windows main folder on Drive C. I do not want to take another risk to fiddle with computer on my own and looking for some suggestions on removing this problem so that computer can be rebooted. Is there any method by which I can reverse the changes made in System 32 and SysWOW64 folders in the ExplorerFrame.dll files or any other solution which can be applied.
Shall appreciate any help to fix this situation
