The System Info page is used for at-a-glance problem diagnosis,Quality Assurance purposes, and as a shortcut to common tasks not limited to information gathering alone.
Many items on this tab can be CLICKED on to perform various functions. If you see your mouse cursor turn to a HAND, then you can click it for some function. Go ahead, click and see what happens!
NOTE: If a field is too short to display all the information, hover your mouse over the label to see the full information in a tooltiptext popup.
Items appearing in BLUE deserve your attention, but are not 'wrong' in any way, they are merely worthy of your attention, for example in the picture the Domain appears in BLUE, because it is in fact, on a Domain and not in a workgroup, something you should know about when working on a system.
Items appearing in RED means there is something wrong.
In the Info column:
- Inst - The data Windows was installed (or repair-installed)
- Env - Environment, e.g. Normal mode, Safe mode, etc.
- User - current user name as reported by the %username% environment variable.
- Path - The user's profile directory as reported by the %userprofile% environment variable.
- CN - The computer name as reported by the %computername% environment variable.
- Domain - Reports if the PC is joined to a domain, of course! Item will appear in BLUE if so.
- Anti-Virus - Reports the A/V software installed as reported by Windows Security Center via WMI.
- UAC - Displays User Account Control status. Clicking this item will toggle UAC on/off. Obviously it does nothing on sub-Vista systems.
- PageFile - This gives an alert to the right in RED when the paging file is too small. D7 calculates the paging file should be 2.5 times the system RAM, or 2GB, whichever is smaller, and alerts you if it does not meet this criteria.
- x Drv - Usually C: Drv, this is your operating system partition. This gives an alert to the right if the partition has less than (I think I set it at) 15% free space.
- CPU - Line one gives the registry string of the CPU, and line two gives the actual speed and HT/Core/CPU count. (D7 cannot differentiate between HT and Multiple core or multiple CPU systems.)
- Video - Gives video info. This can be incorrect if you have (or once had) multiple video adapters installed on the system. Clicking this item offers to take you to the video manufacturer's downloads section of their website.
- MB - Gives the motherboard info retrieved from the BIOS, and hopefully the motherboard model number. In the case of a DELL system, it will give the Dell Service Tag instead of the motherboard model number. Clicking on this label will offer you the option to go directly to the downloads section of the motherboard manufacturer's website, and will also copy the model number of the motherboard to the clipboard, so you can paste it directly into the search box. For a Dell system, it copies the service tag to the clipboard instead. Also on a Dell system, if you choose NO to go to the downloads, it will offer you the option to check the Dell warranty status for that particular service tag.
- BIOS - obvious
- Dump - Displays the minidumps found on the system. Clicking on this item launches BlueScreenView (if installed) to analyze the dumps.
- Uptime - Time the system has been running since the last reboot.
In the Alerts Column:
- Windows Service Pack alert
- IE version alert
- RAM alert - alerts you when RAM is either running low, or just needs an upgrade. D7 decides your RAM needs an upgrade if you aren't running at least 1GB on WinXP, or 2GB on Vista+
- Check Event Log - Appears in RED if there are errors in the event logs since the last system reboot. Appears in BLUE if there are only warnings since the last system reboot. Click this item to launch D7's internal event viewer.
- A/V alert - D7 alerts you when you either have no anti-virus installed, or multiple anti-virus packages installed.
- Paging File check
- Free Space check
- Device Manager check
- PIO Mode check - If D7 suspects a device is in PIO mode that should be in DMA, clicking this item will apply a fix for the issue which requires a restart of Windows. Sometimes the alert is false, as D7 cannot differentiate between MWDMA2 and PIO mode, however applying the fix regardless has no adverse effects. See this option on the Repair tab for more details on the actual repair being performed.
- Automatic Updates check
- Windows Activation check
- System Restore check - Note does not alert if System Restore is BROKEN, only if it is enabled/disabled.
* SPECIAL NOTE - Anti-Virus Software Detection
I get many questions regarding D7's Anti-Virus software detection, and how it works. Mostly people wonder:
- Why is it detecting A/V software (or even fake or rogue A/V software) that I have removed from the system?
- Why does it not detect _______ A/V software?
Maybe this will answer your question. How it works: D7 doesn't detect Anti-Virus software installations themselves. Instead, D7 queries Windows Security Center (WSC) via a WMI call. D7 only reports back to you what WSC returns in the WMI query.
When Anti-Virus software installs, it registers itself with WSC (or it should, however some off brand A/V packages and even reputable ones that didn't install 100% properly may not correctly register themselves with WSC...)
When Anti-Virus software is uninstalled, it removes itself from WSC (OR IT SHOULD.) Some A/V uninstallers merely do not remove themselves from WSC. In the case of ripping malware (rogue A/V's) out of a system that have registered themselves with WSC, obviously that information wouldn't be removed from WSC.
But how to fix these phantom entries? The easy answer is to use D7's Repair WMI/WBEM/DCOM function on the Repair tab. Among the many things this does, it also clears phantom A/V entries from WSC. The only downside is that some A/V software only registers with WSC during install, not on every startup when the info is missing, so if you have legitimately installed A/V software and use this repair function, D7 may no longer recognize your installed A/V product unless you reinstall it. As a result, your best practice (where possible) is to remove all A/V software from the system, perform the repair mentioned above, and then properly install your intended A/V software.
How to see what Windows sees and verify D7 is correct - and how to pluck out a specific A/V no longer present without using D7's Repair functionality.
- From an elevated (admin) command prompt, type WBEMTEST and hit enter.
- In the new window, click the Connect button
- In the new window, under the Namespace entry, type root\SecurityCenter and click the Connect button
- Next click the EnumInstances button, and in the box type AntiVirusProduct
The final window that pops up will show you what Windows thinks is the Antivirus software (and what D7 queries to get it's information). From here, you should be able to selectively delete A/V products that are no longer installed.
