Find the Windows Version of a non-booting PC? Boot using a Linux Mint CD or Memory Stick and use Nemo (the Mint file manager) to open Windows/System32/license.rtf If it does not show you the actual Windows Version, it means the system was running Windows 10.

Malware: If you still have a problem with malware after the above steps, or if one of the steps, like Malwarebytes, fails or loops forever, you might as well cut your losses and go for a complete reinstall of Windows (after backing up your data). It is easy to waste time and money on virus and malware removal tools from major companies that simply do not work. Windows 8 to 10 have System Refresh which keeps your documents, photos etc. safe.

Windows 7 Login Profile Corrupt Error: Reboot and keep pressing F8 as your computer starts until you see the boot options menu. From there click on 'Safe Mode'. From Safe Mode, restore your PC to a date a few days before the Profile Corrupt error occurred.

Windows 7 Microsoft Teredo Tunneling Adaptor not working: Open regedit and navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\TCPIP6\PARAMETERS. In the right pane, right click Disabled Components and select edit. Set the DWord value to 0. Restart your computer and check in Device Manager that the exclamation mark has gone.

Windows 8 Blank screen after login: Wait 5 minutes to see if it eventually completes the log in. If it fails, consider Refreshing your PC. This should resolve the problem without affecting your data, though you will need to reinstall programs. Restart your computer and at the Login screen hold the shift key down and click the shutdown button, then click Restart. A 'Choose an Option' screen will be displayed. Click 'Troubleshoot' and then 'Refresh your PC'.

Windows 8 Lenovo: Uninstall Browserguard to resolve problems with AOL desktop. It also triggers antivirus software so is best removed.

Windows 8 Lenovo: May have a BIOS vulnerability introduced by Lenovo. Remove it here.

We're open from 09:00 to 17:30 Monday to Friday. We are closed Christmas, New Year and Easter.
