1. Disable the Windows 10, 8, or 7 Superfetch


Enable or disable the Windows 10, 8, or 7 Superfetch (otherwise known as Prefetch) feature. Superfetch caches data so that it can be immediately available to your application. Sometimes this can affect the performance of certain applications. It tends to not work well with gaming, but can improve performance with business apps.
To modify whether Superfetch is enabled or disabled, you can perform the following steps.

Disable from Services

1. Hold the Windows Key, while pressing “R” to bring up the Run dialog box.
2. Type “services.msc“, then press “Enter“.
3. The Services window displays. Find “Superfetch” in the list.
4. Right-click “Superfetch“, then select “Properties“.
5. Select the “Stop” button if you wish to stop the service. In the “Startup type” dropdown menu, choose “Disabled“.

Enable or Disable from Registry

1. Hold the Windows Key, while pressing “R” to bring up the Run dialog box.
2. Type “Regedit“, then press “Enter“.
3. The Registry Editor window appears. Navigate to the following location in the Registry.
   • HKEY_LOCAL_MACHINE
   • SYSTEM
   • CurrentControlSet
   • Control
   • Session Manager
   • MemoryManagement
   • PrefetchParameters
4. On the right side, double-click on “EnableSuperfetch“. If this value doesn’t exist, right-click the “PrefetchParameters” folder, then choose “New” > “DWORD Value“.
5. Give “PrefetchParameters” one of the following values:
   • 0 – to disable Superfetch
   • 1 – to enable prefetching when program is launched
   • 2 – to enable boot prefetching
   • 3 – to enable prefectching of everything
6. Select “OK“.
7. Close the Registry Editor.

Note: If you disable Superfetch and would like to enable it for certain applications, you can use special switch in the program shortcut: /prefetch:1

2. Dissable by net service

Using NET to stop a Windows Service

To stop a service, run:

net stop <Service-Name>

c:\>net stop "windows Search"

Starting a Windows Service with NET

To start an idle Windows Service, run:

How to identify your Tablets Processor and Board ID

How to identify your Tablets Processor and Board ID?

The process of identifying your tablets firmware begins with knowing your Tablets Processor and board ID, believe it or not most of these entry-level Chinese tablets are usually sporting similar boards and processors for the most part, the names of the devices might change e.g. Alldaymall, Irulu, GPad or so on but beneath they are sporting similar hardware and all you have to do is find a firmware that matches the board ID and the processor or ones thats close and you can flash your tablet and have it functioning as new. The two main type of processors that you will find on your tablet are usually the A13 and A10 processors respectively.

To find out both you will need to open your Tablet, do not panic it’s not as bad as it sounds trust me, here are the steps:
1. Tablets do not have screws that seal them in most cases so you will have to find the seems that hold both halves together.
2. Once you have found the seems, use a tool set such as the ones used in opening phones or a blunt object and force it into the seems,its best to start around the charge port in most cases, the parts will separate with little trouble as long as you are firm-do not break the clips that hold both halves together but separate the halves until the entire thing comes apart.You can refer to the video for details instructions.

3. Once both halves separate, carefully move them apart and watch out for wires such as the one that runs from the speakers.
4. Look on the main part of the board and you should see a processor look out for A13 or A10 marked on them clearly:


5. Last look on the board for a number its usually at the top section and it’s clearly written, this will be your Board ID, record it:

That’s it you have just found your Motherboard ID and Processor, in this case the board in the tablets ID was: CB-M RU 94V-0
The processor was: A13
So now I need to search in Google for “A13 CB-M RU 94V-0 Firmware”

BIOS Password

Laptops in general have much better hardware security than PCs. Some of them even come with fingerprint reader build in.

 

Most laptops come with a very strong BIOS password capability that locks up the hardware and makes the laptop completely unusable. This is the password that has to be entered before the operating system loads, usually on a black screen a few seconds after the laptop is started.

 

Of course BIOS password can be set on a PC too, but there it is stored together with the other BIOS settings – date, time, hard disk size, etc. It is very easy to reset the BIOS settings (and the password) on a PC – usually there is a jumper near the BIOS battery on the motherboard that needs to be moved from connecting pins 1+2 to pins 2+3 for a few seconds and than moved back to pins 1+2. Next time the PC is started it will alert you “… BIOS settings invalid… Defaults loaded… Press F1 to continue…” or something similar, and…. the password is gone!

 

However most laptops store the BIOS password in a special chip, sometimes even hidden under the CPU, that is not affected when the rest of the BIOS settings are reset. This makes the removal of a BIOS password on a laptop almost impossible. The only option in most cases is to replace the chip which is quite expensive and risky procedure and, of course, not supported by the manufacturers.

Some manufacturers (like Dell) can generate a “master password” for a particular laptop (from their service tag) if sufficient proof of ownership is provided. Others (like IBM) would advise replacing the laptop’s motherboard (very expensive). On some old laptops (4 – 5 years or older) the BIOS password can still be reset relatively easy, usually by shorting two solder points on the motherboard or by plugging a special plug in the printer port, etc.

 

In almost all cases on newer laptops it is either a big hassle, expensive or even impossible to reset the BIOS password, making it a very good way of protecting your laptop from unauthorized use.

However what makes your computer exactly yours are your own files, documents, emails, pictures, etc. They are all stored on the hard drive. So, even if your laptop has a BIOS password that locks it up and makes it completely unusable to anyone that doesn’t know it, your hard drive can still be removed from the laptop and connected to another computer, and your files retrieved quite easily.

 

How do I clear a laptop BIOS or CMOS password?

  A laptop BIOS password is more secure than a traditional desktop to help protect the data if it was stolen. If you are the original owner of the laptop, we highly recommend contacting the manufacturer of the laptop. Companies such as Dell, Lenovo, and Toshiba can reset the password if you are the original owner using the Service Tag, disk, or give you exact steps for your laptop.

If you are not the original owner of the laptop, there are some ways to bypass the password depending on the manufacture and model of the laptop.

5 to 8 character code on System Disabled screen

 

    In the CMOS setup, when prompted for a password, guess three times until you're giving the code. If, after entering the wrong password three times, the computer is displaying a 5 to 8 code, as shown in the picture, continue to the next step.
    Write down the code and visit Dogbert's BIOS Password Backdoors scripts page to download Python and the free Python scripts to clear many of these types of passwords.
    As the computer is booting, press F1, F2, or Del to enter CMOS setup.

Clear by dip switches, jumpers, jumping BIOS, or replacing BIOS

If the above suggestions do not apply to your laptop, you need to open the laptop and clear the password using dip switches or jumpers. You may also be able to jump the BIOS using a paperclip, by soldering a wire to pins on the BIOS, or replacing the BIOS chip.

The location of dip switches or jumpers on the motherboard depends on the brand and model of your laptop. Check the technical documentation for your laptop and contact the manufacturer to determine which motherboard is in your laptop. Search the Internet for that motherboard model for a technical diagram of where components are located, including the dip switches or jumpers for resetting the BIOS.

Which step you take depends on the manufacturer and model of your laptop computer. For most end users we highly recommend having the laptop serviced by a qualified technician who can properly disassemble a laptop.

Contact laptop manufacturer

If the above steps do not help remove the CMOS password for your laptop, we suggest contacting the laptop manufacturer for steps on how to clear the password. Many manufacturers have strict policies in place to help protect their customers' laptops and only they have the information on how to clear CMOS passwords.
