erratic screens; windows8.1 missing files

[vze81cra]

can't change date & time due to mouse not being able to select drop down panel options; screen only goes up, opening screen won't allow me to login in unless I swipe the first screen by hand. Tried erecovery, window8.1 asking for installation key which I don't have since it was a free upgrade. can't select installed printer to print, screen defaults to fax. Oringinal OS was 7 ultimate, upgraded to 8, then 8.1, then the problems started.

First of all, you need to buy an official activation KEY for Win 8.1

Right-click start, click command prompt (admin), launch:

dism /online /cleanup-image /checkhealth

It should last few seconds, then report the final result here.

After it, launch:

sfc /scannow

It should last 15-50 minutes, then report the final result here.

Then launch this command:

copy %SYSTEMROOT%\logs\cbs\cbs.log %userprofile%\desktop\cbs.txt && findstr /c:"[SR]" %userprofile%\desktop\cbs.txt > %userprofile%\desktop\SR.txt

After it, you should find two files on your desktop: cbs.txt and SR.txt.

Post here the sr.txt .

If the command won't work, try these, one after the other (one by one):

copy %SYSTEMROOT%\logs\cbs\cbs.log %userprofile%\desktop\cbs.txt
findstr /c:"[SR]" %userprofile%\desktop\cbs.txt > %userprofile%\desktop\SR.txt
