registry edit, windows tweaks, etc. yes, i can't access reg editor but i have another pc and i can acces reg entries via network
dude, the reason you cant access your reg editor is a malware infection which cannot be resolved by a registry tweak. i have seen this on my own computer. But...its your baby. good luck!
registry editor have connect network registry function (works only if target machine's remote registry service started) but if you experienced this and resolved via malwarebytes, of course i prefer this and for usb keyboard issue, yes i have usb keyboard but legacy usb support in bios already enabled and i tried ps/2 connection also. otherwise, 32 bit memory limit removed win7 boot's advanced options already work, i said
well, i find first solution for regedit.exe finding problem, both automatically and manually malwarebytes detects causing malware and removes & shows information about this. it's automatic solution manual solution; this malware modifies HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options key by creating sub key named regedit.exe. every sub key named with an executable's name in image file execution options key, redirects associated executable to another selected executable specified in (default) string and/or just associating another executable specified in debugger string for debugging works etc., executables starts together. so, malware's sub key redirects not existing executable because sub key's string doesn't have a value now, it's time to find second solution, f8 key problem
