i installed windows 10 around 1 hour ago and installed nothing but chrome,dropbox,avg antivirus, jre jdk and netbeans.
all are certified (nothing is pirated). and for some reason i cant open any file or driver, other programs work well including the browser. i tried scanning for virus, avg and windows defender found nothing. i tried running REGSVR32 /i SHELL32 but it didnt work- it failed for installdll problem...
can someone help me solve it? im working with lenovo y50

when trying shell32 i get error code 0x8002801c.
