“Windows cannot access the specified device, path, or file. You may not have the appropriate permission to access the item.”
I get the error no matter what I open a program, I can’t even access Run As Admin or go to Programs and go to components; also tried removing Bitdefender firewall and antivirus but I don’t think that’s a problem because this error occurred 2 or 3 days after I installed it. Is there any fix to it? I have also looked on the other threads and I have tried them and they don’t seem to apply to me.
I am Running:
Windows 7 (for information)


this is not a big issue, its very easy to solve if you have some know how of system registry because some of your files are disassociated from registry values that is why the problem occur. this not only happens with device manager but many other programs can disassociate, for this you have to clean windows registry if you can otherwise use some kind of registry repairer software like reginout.
Your not the administrator. You have to be the admin. Right click on the file and press “RUN AS ADMINISTRATOR”
If the error occurred 2 or 3 days after you installed Bitdefender Firewall….get rid of it…..Bitdefender AV is good enough by itself……then do this >>> System Restore………go back about 3 or 4 days before you were having this problem….
