Unusually Operating System is installed on C drive and whenever you install new program it goes to C:Program Filesprogram name

I is because the default suggested installation path is C:Program Files.
It can cause a problem when C drive is been wrong partitioned and the size of C drive is small
You can use registry to change the default application installation path to for example install in D:Programs,
To set different default installation path, follow the steps bellow:

1. Pres on start
2. Type in run regedit
3. Navigate to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersion.
4. At the right panel, loacate ProgramFilesDir.
   
5. Double click on it to change the value to your desired path. For example, change the value from C:Program Files to D:Programs.
