I have a Toshiba Satellite L755. Recently it began showing a warning that says something like the computer was running an unauthorized edition of windows. it also won't install any updates and I can't install or uninstall anything.
Computer OS: Windows 7
I've run the windows troubleshooter. It says it fix the updater problem but I still can't install updates
Welcome to Justanswer
It is possible that your Windows 7 installation is not yet activated
In this case you should run the Windows Activation tool by clicking on the Start button and then entering: slui.exe
Follow the instructions on the screen to activate your Windows 7
If this doesn't help or in case your Windows 7 is already activated, you should do a System Restore to reset your configuration to a date when Windows was still working.
After logging in to Windows, click on the Start Orb and type the command: rstrui.exeAlternatively you can click Start -> All Programs -> Accessories -> System Tools -> System Restore.You will then see a window where you can choose a date to restore your system to. Click on an available date when your computer was still working and finish System Restore.Your system will restart and restore itself.

I've tried system restore but I can't seem to get a restore point older than a week or so.
In this case there are no system restore points that are older than one week.
Have you tried to manually activate Windows?
Hi Thomas, sorry about delay. I waited for a while but had to go to work. I admit I'm not that computer literate, but I thought the computer automatically created restore points. I haven't tried to activate windows manually because it worked fine up until a couple weeks ago. I've had the computer several months now. I don't know but i think I picked up a virus although when I run a scan with Norton it doesn't find anything. I will try to activate windows manually and see what happens.

I tried to activate manually. It said it was successful and could install updates now. When I tried it looked like it was going to work but then it failed. Said it encountered an unknown error. Then gave error codes 8000FFFF and FFFFFFE.
Thanks for your reply.
Microsoft offers a fix for the error 8000FFFF.
Please go to:
There is a "Fix It" button on the website that downloads a small tool which can automatically fix this error.
When I tried to install the fix it tool it says download failed. Encountered unknown error. Then error codes 2503 and 2502. this happens whenever I try to install anything
That sounds like your Windows 7 system configuration is seriously damaged. It could be a virus infection.
The best way to solve this problem would be to backup all your files and then restore the notebook to factory default.
To restore it restart the laptop and wait for the Toshiba logo to appear on the screen.
Press the key that brings up the hard drive disk utility menu. In most cases the key will either be "0," "F1" or "F8."
Press "1" or click "Restore Original Factory Image." Click "Yes." Select "Next" to begin the restoration process.
Restart the Toshiba laptop when the restoration process finishes. Follow the prompts that appear on the screen to set up the laptop's date, time and language settings.
After the restore process, copy your files back to the hard drive.

Hi Thomas, Thanks I think that is what I will have to do. I'm not real sure how to back up my files. Sorry if I seem like a complete idiot. When it comes to computers I
