I have had windows 7 for 18+ months working on my computer.

Hi my name is Jeremy, I would like to assist you with your question. I am an expert here on JustAnswer.com in the computer field.

How are you doing today?

A lot of times Microsoft Office comes pre-installed on the computer as a limited trial. When this happens it will let you use it for a certain amount of time then try to force you into buying the application.

If you purchased Office however a re-install will correct this issue using the Office CD.

I do however have a really great suggestion for you.

You can install Open Office which is brand new, is near identical to office, and more compatible, it's always up-to-date. Also it's 100% free.

I along with pretty much everyone of my customers prefers Open Office over Office .

Here is what you need to do to install it

Click the link above. A download will begin. It will ask if you want to run or save. Choose Run

Follow the prompts to complete the installation. Once installed you will notice an Open Office icon

About the only difference you will notice is that Open Office uses different names for the applications. (example: Word is called Writer Excel is called Calc, etc)

It also is compatible with Office 2013 and older versions of office. This program is absolutely perfect for you to write drafts, letters and advanced projects if you ever needed to (spreadsheets, powerpoint presentations, etc).

If you ever have any questions on open office you can reply to me anytime and i'll help you in any way I can

If you have a moment don't forget to rate my help below (an excellent service rating is most appreciated) (To rate my help click the smiley faces below then press the submit button)

Thanks again for all you patience

Jeremy

You may want to try to boot into Safe Mode and see if it lets you in and try a system restore. It sounds like something in Windows is corrupt

To do that

Shut the computer off

Turn it back on and rapidly push F8 on the keyboard.

Use the arrow keys to select Safe Mode then push enter

Once in safe mode

Hold the Windows Key (looks like a flag on the keyboard) and press r

In the run box type rstrui then push enter

This will bring up the system restore.

Try restoring it to a previous date.

Let me know if that does the trick

An alternate solution would be a system recovery of the Sony. This would however restore it to how it came from Sony

To do that

Turn the Sony off

Turn it back on and immediately tap F10 on the keyboard

It will bring up the system recovery options and allow a complete restore.
