Can I install Windows 10 Pro (64bit) to my CQ40 laptop?

Hi,

I want to upgrade my OS from Windows 7 ultimate (64bit) to Windows 10 Professional (64bit). Can I run the Windows 10 on my old laptop with normally and without lagging?

Specifications:

- Processor : Core 2 Duo T9600 (I upgraded my processor from Pentium T4200)

- Ram : 4GB DDR 2 (Max)

- HDD 250GB 4300Rpm (this is so slow obviously)

Please give me an advice

Given the date of your post, I would have expected someone to respond to it before this -- but since that has not happened, I will take a shot at it ...

The main issue you are going to run into with a laptop this old is the lack of Win10 video drivers.  Different models have different video chips but they all share one problem -- a lack of current Win10 video drivers.

If you are forced into using the infamous Microsoft Basic Display Adapter, your PC is going to slow to nearly a halt and be unusable.  I know because I have a really old laptop that also does not have Win10 drivers, and it is useless under Win10.

If it were mine, I would do the following 
1) Use Macrium Reflect to create a backup on a large USB stick or external drive (see below)
2) Use this link to download and create Win10 install media: https://www.microsoft.com/en-us/software-download/windows10
3) insert that into your PC (do NOT boot from it), find the folder containing the media, select the setup.exe file, right-click that and select Run as Administrator.  This will start an in-place Upgrade which could then take a couple of hours to complete.

If you are presented with a window asking for a product key, down near the bottom is a entry you can click to skip that. Do NOT enter a product key, as it will reuse your existing key and when you finish and get back online, Windows will automatically reactivate.

------------------------------

I personally prefer to use third-party Backup solutions as they tend to be both more flexible and more reliable than any built-in solutions.

Macrium Reflect (MR) provides a FREE version that can be used to image and restore partitions or entire drives.

What I recommend is the following:
1) Download and install Macrium Reflect (MR) from here: http://www.macrium.com/reflectfree.aspx
2) Run MR and choose the option: "Create an image of the partition(s) required to backup and restore Windows" to write a full backup to an external drive or USB stick
3) Use the option to create a boot USB stick or CD

My experience is that MR, when using the High Compression option, typically can compress the saved image file to about 50% of the USED space in the OS partition. This means if you have an 80GB OS partition, and 40GB is used, MR only needs about 20GB to store the image file.

I use this all the time and it typically takes less than 15 minutes to do the image backup and about the same time or less to do a restore.

NOW, you have the means to restore a full working system from the external drive or USB stick in only a few minutes.

Thanks for your advice but I will not to re-install my windows 7 to windows 10 because my laptops are slow enough for surfing.
