Hello,
By a clean boot we mean the Windows OS loaded with as few programs, services, and user options as possible.
The following is from my notes on how to do a clean boot:
Log on to the computer by using an account that has administrator rights.
Click Start, type msconfig.exe in the Start Search box, and then press Enter to start the System Configuration utility.
If you are prompted for an administrator password or for confirmation, you should type the password or provide confirmation.
On the General tab, click the Selective startupoption, and then click to clear the Load startup items check box. (The Use Original Boot.ini check box is unavailable.)
On the Services tab, click to select the Hide all Microsoft services check box, and then click Disable all.
Note This step lets Microsoft services continue to run. These services include Networking, Plug and Play, Event Logging, Error Reporting, and other services. If you disable these services, you may permanently delete all restore points. Do not do this if you want to use the System Restore utility together with existing restore points.
Click OK, and then click Restart.
For more information about how to perform a clean boot in Windows 7 see the Video: How to do a clean boot in Windows.
After the computer is restarted, you now have a clean boot environment. Do one of the following as appropriate:
· If you previously could not install or uninstall a program or an update, try to install or uninstall the program or update again.
Note If you receive the "The Windows Installer service could not be accessed" error during the installation or uninstallation, follow How to start the Windows Installer service when system services are not loaded, and then install or uninstall the program or update again.
· If the installation or uninstallation is successful, you have resolved your issue. Follow How to reset the computer to start as usual to reset your computer to the normal startup.
· If the installation or uninstallation still fails, that means this issue is not caused by application or service interference. You may have to go to Microsoft Support
for more specific support.
· If you previously could not run a program, try to run the program again.
· If the program runs correctly, that means this issue is caused by application or service interference. Follow How to determine what is causing the issue by performing a clean boot to determine what application or service causes the issue.
· If the program still does not run as expected, that means this issue is not caused by application or service interference.
I hope this helps; keep me posted.
