Common Solutions

What are some common solutions for software problems?

RebootRebooting the computer resolves many issues
There can be many unnecessary programs occupying the memory, and they will close when the computer is rebooted
Always reboot the computer  
Restart ServicesA service that has crashed or is not responding can be restarted
Go to Services, find the service that is affected, and restart it  
Uninstall / Reinstall / Update ApplicationsUpdate affected applications if an update is available
Repair the application if a repair option is available (from Add & Remove Programs)
Uninstall and reinstall he application if no updates are available and the repair fails or is not available  
Add ResourcesAdd additional hardware (RAM or hard disk space) if the current hardware is overloaded

Verify RequirementsVerify that your computer hardware meets the requirement of the software that you are running

Change or increase the hardware if necessary

System File CheckRun the system file check to find errors with system files and repair them (see the section on Windows commands for more details)

Repair WindowsRepair the Windows installation

RestoreRestore Windows to a time when it was working

Apply UpdatesApply updates to drivers, the operating system, and/or software programs  
Roll Back UpdatesUninstall recent updates if they are the source of the issues

Disable Windows Services/ApplicationsDisable services that are causing issues
Disable applications that are causing issues
This isn’t an ideal option because some applications/services may be necessary  
Disable Application StartupDisable applications that automatically load with Windows

Safe BootSafe Boot loads Windows with only minimal applications/drivers
Once Windows has loaded with Safe Boot, enable applications and drivers one at a time until the error reappears
Safe Boot is only for diagnostics and isn’t an option to use regularly  
Rebuild Windows ProfileDelete an affected Windows profile and log in again.  This will allow Windows to rebuild the profile.

ReimageErase the entire computer, reinstall Windows, and reinstall all the applications
This is a last resort when all the other attempts to repair the issue have failed
