Does Windows keep telling you that the computer needs to restart to finish installing updates even after you have already restarted the computer repeatedly? Here’s how you can fix the problem.

It is paramount to install these updates correctly because getting the latest updates means getting the latest security fixes that prevent infections from compromising your system.

Before trying anything else, run a System Restore:

In Windows 7, click the Start button, click the Accessories folder, then System Tools, and select System Restore.

In Windows 8, use the mouse to swipe the right edge of the screen of the cursor, then click the Search Charm.

In the box that comes up, type restore point and click Create a restore point.

Choose the last date your computer worked correctly before the failed update. In the System Restore Wizard window, select the restore point that corresponds with that date. If the wizard doesn’t display the date in question, check Show more restore points.

After you have found the correctly dated restore point, click Next. Then select Finish to allow Windows to run the wizard and reboot.

After rebooting, run Windows Update again.

If Windows fails to update again, malware may be the culprit. Malwarebytes anti- malware is a useful tool that can remove these types of infections that block updates. For more information on how to remove malware, please refer to the following article.

If the failed updates are not the result of malware, try the Windows Update Troubleshooter. It is a free Microsoft diagnostic tool that can sort out update problems.

If all of the solutions mentioned above cannot rectify Windows update, try rebooting one more time. Sometimes temporary problems arise that prevent updates from installing. A simple reboot often clears Windows of these problems.

As a last resort, you can reset windows update. This is a very complicated process that involves precisely following the steps described in this Microsoft support article.

Do other people use your Windows computer? If so, you probably want to prevent them from installing programs that you are unaware of. If you are the only one using your computer, you may simply want more security and control over what gets installed.

Here we will show you how to require a password for anyone to install software on your Windows Vista/7/8 computer.

First you must be logged in as a user with administrative privileges.

To do this from Windows 7 or Vista, first click the Start button and select Control Panel.

From the Windows 8 Desktop, drag the mouse to the right edge of the screen to allow the Charms bar to appear. On the bar, click Settings (represented by a gear icon).

From Settings, select Control Panel.

From Control Panel, use the drop- down arrow next to View by near the top right of the screen. Select Category from the drop- down selections.

User Accounts and Family Safety is one of the categories that will appear. Under this category, click Add or remove user accounts.

Select Create a new account.

Choose the name for the new account. This can be the name of another person using your computer or the name for another user account used by you. Make this user a Standard User. This will require the user to enter an administrative password whenever they want to install a program. Click Create Account.

To give it a password, click the icon representing the account you just created and select Create a password.

After entering the password twice and typing in a password hint, click Create password.

Log out of Windows and re-login under the new account name. Now programs will not be able to install without your administrative password being entered.

Zero Day Internet Explorer Exploit Targets Users

A zero day exploit affecting Internet Explorer 6 through 11 has been discovered which allows an attacker to execute code and install malicious software. Security firm Fire Eye has recently released the details of how this attack works.

Internet Explorer accounts for about 25% of the worlds browsers used to surf the internet. We will cover a high level summary and how you can protect yourself and your business.

How does it work?

The exploit works by loading a corrupted Adobe Flash SWF file in a webpage, which allows the attacker to modify data in memory, effectively bypassing Internet Explorer’s security and allowing any malicious software to be downloaded and installed. This can include viruses, malware, keyloggers, bitcoin mining software, fake anti-virus programs among other destructive software.

Rapid 7 shows an attack on a Windows 7 system using this exploit.

The exploit can be used on any version of Windows that runs IE 6, 7, 8, 9, 10 or 11, which means this is the first time that running a newer version of Windows does not protect you from an exploit.

What can I do to protect myself?

Microsoft has already started rolling out an update to patch the security bug, so be sure to keep your operating system up to date. It is also recommended that you install Microsofts EMET 3.0, which brings better security protection especially for older Windows operating systems.

As always, we recommend running more secure and light weight web browsers such as Chrome or Firefox and avoiding Internet Explorer unless absolutely necessary.

All Onsite PC Solution clients with monthly maintenance plans will automatically be patched during their next monthly maintenance cycle.
