Unlock Windows 7 Password by Third-party Software

If you don't have a password reset disk and can't access any administrative account on your win 7 computer, then you need to create a bootable disk with Windows Password Recovery Tool Standard (Click to download). You can download it on any other accessible PC, then burn it to a CD/DVD and then boot your computer from the disk and it allows you to unlock password Windows 7 instantly.

1. Download Windows Password Recovery Tool Standard and install it on any accessible computer.
2. Burn it onto a CD/DVD.
3. Boot your locked computer from the newly burned CD/DVD.
4. Wait until the boot process is finished. When a window pops up with all your Windows accounts, select a user account and click Reset Password button to reset your lost Windows 7 password.
5. Click the Restart button to reboot the win 7 computer, now you can log into your win 7 system without any password.

It is annoying when you forgot or lost your Windows 7 password. However, with the Windows 7 password unlocker (Click to know more info) solutions above, you can unlock your forgotten password and regain access to your Windows 7 OS easily and quickly.

On boot up tap the F8 key until you get a menu. Select Safe mode. If it boots disable all startup processes and services by clicking Start, run and type msconfig. Reboot, if it boots the you can enable one item and reboot until it no longer works and you will have your culprit.

just right mouse click on your desktop and and scroll down to personalize if it is win 7 and then click and desktop background and select you desired background

Step 1: To turn off the hover option on your Windows 7 laptop, click your Start button (bottom left of your screen), then type main.cpl in the search box and click Enter on your keyboard. You can also go to your Control Panel, click Hardware and Sound, then choose Mouse beneath Devices and Printers.
Step 2: When the Mouse Properties box opens for your trackpad, choose the Device Settings tab to the far right, then click the Settings button below Devices.
Step 3: Double-click the word Tapping (or click the plus sign in front of Tapping once) in the list to the left, then uncheck Enable Tapping. Click OK for both boxes, and you're done. Now you can click when YOU want to click, not when your mouse decides to.

I would verify that you have the compaq drivers installed for the mouse pad NOT the microsoft defaults alot of the time they add functionally like the double tap click and things like that. The link is

Its under input devices I selected windows XP I dunno your operating system but if your operating system is Windows xp that will work.

Like this if it worked for you. PLEASE!!!!

First, try double tapping the light again. You may have just mis-tapped.

Next try restarting the laptop. Certain laptops re-enable the track pad on restart so long as a USB mouse isn't connected.

If that fails, navigate to the Mouse Settings on your PC and re-enable it there. If you have a USB mouse you can use that. If not, you can use the keyboard. Windows Key will launch the Start Menu, arrow keys can highlight options, Enter will click on them, Control+Tab and Control+Shift+Tab will switch tabs (in a window that has tabs).

In Windows XP and 7 (and probably Vista), Mouse Settings is located at Control Panel > Mouse > Settings.

What Model is your Laptop? if the Touchpad went off, you will be able to see a red Touchpad light on! if so, please quickly double tap on that color! I hope that works for you!
if not working, please reply with your PC model number!!! (ex. Compaq Presario CQ32)

1. The touchpad and external mouse drivers should be able to work together. Just make sure that you have the touchpad enabled. To see if you have the touchpad enabled, hold the Fn key and press F9. The combination Fn-F9 locks and unlocks the touchpad. If pressing Fn-F9 once, twice, thrice does not seem to lock/unlock your touchpad.. then you might not have the Toshiba hotkeys working or enabled. So lets forget it and try step 2. If Fn-F9 solved your problem.. there you go !

Arrow The way it works is you have to keep holding Fn key and have to hit F9 once, that should lock the touchpad. Again if you keep holding Fn and hit F9 again, that should unlock it and so on..

2. Sometimes this solves the problem.. Do a power cycle of your computer.. i.e., unplug the AC.. take the battery out.. Plug the AC back in and try to turn computer ON with AC alone (i.e, leave the battery out and just start computer with AC power).. Once windows loads up and everything is fine, then turn system off. Unplug AC.. put battery back in.. Plug AC back in and restart computer.. All should be working now.. if not, keep reading..

3. Click on START>go to RUN>type devmgmt.msc

4. Now in the Device Manager, click on the + sign next to Mice and other pointing devices. Right click on each device listed under "Mice and other pointing devices" and Uninstall ALL the MOUSE Devices you see listed there..

attention Make sure you ONLY uninstall the Mouse devices and not ALL devices from Device Manager like your CD, Display etc.. Just uninstall the devices listed under Mice and Other pointing devices after you have clicked on the + sign to the left of it..

5. Go to http://support.toshiba.com there click on Downloads.. select your computer.. Product=Portable, Family=Satellite, Model=M35X-S149.. then click on "GO" button on the right.. Again in the next page that comes up click on "Downloads"..

6. In the page that came up saying Downloads ( All operating systems, All categories ), at the top drop the list Filter by Operating System and select Windows XP (I am assuming you have XP.. if you have another OS, select that instead).. then on the right of it, drop the list Filter by Category and select Touchpad.. then click on the button "Apply Filters"..

7. Now you just see two drivers listed..

09-30-2004 Toshiba Utility
Touchpad Toshiba Touchpad Enable/Disable Utility for Windows XP (v1.27.0.3; 09-24-2004; 5.34M)

06-15-2004 Driver
Touchpad Alps Touchpad Driver for Windows XP/2000 (v6.0.303.5; 05-26-2004; 2.43M)

Click on the Download link on the right.. Save them to your computer somewhere in a folder or desktop, where you can remember.. After the files are downloaded, double-click on the file.. Unzip.. then Run.. and it will install the driver..

8. Restart your computer.. Now the Touchpad should be working fine.. Try Fn-F9 combination.. i.e, keep holding Fn key and tap F9 once, twice to see if it locks/unlocks the touchpad..

If above doesnt solve it, then please post any errors that you get and I will see if we need to try something else.

Thanks for using fixya...
