Q  Ever since I bought a Dell laptop with Windows 10, updating Windows has become a nightmare. It takes several hours over a Jio connection and I am often told that the update could not be installed. Is there another way to instal the updates? I have a similar problem with Office 2013 updates.

First, any mobile Internet connection will hamper your work, as the data is limited to 1GB a day after which the speed drops drastically. You should have a wired broadband in your home or office connected to a WiFi router. Operators such as Airtel, Alliance and BSNL provide wired broadband. Get a connection with a speed of 8 Mbps or more. To manually download Windows updates, you need to check the current version of Windows 10 you are running. You can check this by pressing Windows key + R, and type: winver and then hit Enter. The dialog box that opens will reveal the update version installed on your machine.

Next, go to this URL from your browser: com/en-us/help/4000825/windows-10-windows-server-2016-update-history. Download the most recent update. This will ensure that you get versions that you may have missed. Save the downloaded file to your hard disk and run the .msi at your convenience to instal it. Similarly, you can download the Office updates from and manually instal them.

Pen drive format

Q  The file system on my Sony 16 GB pen drive has changed to RAW. I am not able to format it.

This can happen when you do not safely remove the pen drive from your computer. Go to go to and download version 4.40 of HDD LLF Low Level Format Tool. After you use the tool, the contents of the pen drive will be erased. Now you will be able to format it in Windows or whatever tool you choose.

iPhone X

Q  I am planning to buy an Apple iPhone X from the US. Will the models sold there be compatible with the 4G LTE network available from Vodafone, Reliance Jio or Airtel?

Ajit Kumar Kundu

The model A1865 (GSM) will support the LTE bands offered in India by the various operators. This model is also sold in the US. The other model sold in the US will not be able to access the LTE bands of Indian operators. It has become more difficult to identify the model number in the iPhone X since Apple has stopped etching it on the back of the phone. Now you have to insert the SIM card removal tool into the SIM card pin slot and take out the tray. The model number is etched on the top of the slot. Another way is to go to Settings on the phone, navigate to General-About. Tap on Model and it will show you the model number beginning with A.

Restore power

Q  The screen on my Windows 10 Dell laptop becomes dark every time I start the machine. I have to open the display options and adjust the brightness to continue working normally.

Dilip Ganguly

There is something wrong with the brightness setting in the power options. Go to Power Options and choose a plan and restore it to default. If the problem persists, choose a plan and select Change Plan Settings. Next, go to Change advanced power settings. Scroll down to Display and click on the plus sign. Scroll down until you see Enable adaptive brightness. Expand it. By default, Battery and Plugged in should be on. Switch them off and see if it improves.

Malware detector

 Please recommend a safe malware detector and remover for Windows 10.
