I use Advanced SystemCare, CCleaner and MBAM to scan / remove issues on my laptop about once a week.
About a year ago I downloaded a similar program from CNet Downloads and ran a scan / clean. However, a few days later I noticed I get errors for example when right clicking on the desktop and clicking 'personalise', I now get an error - 'explorer.exe no such interface supported' and similar issues like when in 'Control Panel\System and Security' if I click a sub-category nothing will happen.
These errors don't have any effect on my laptop for daily tasks, but 'niggle' at me now and again.
I don't have my Windows 7 disks with me, their at my house some 200 odd miles away (not going back for a while), but was wondering if there was a way to repair my system without the disks?
