Problem:

A delay between switching folders in inbox, which is als present when switching back to inbox from other places such as Calander and Contacts. This can be fixed by disabling hardware accelleration.

Solution:

There may be a control for this in file/options/advanced under “Graphics” or “Display”. If not, you’ll have to edit the registry.

Step 1 – open your registry. Press the windows key and type “Regedit” then press enter or click the Regedit icon, windows 7 users you can type Regedit in your start bar.

Step 2 – Browse to: COMPUTER HKEY_CURRENT_USER Software Microsoft Office 15.0 Common Graphics. If you don not have a “Graphics” right click on “Common” and choose “New” then “Key” and create “Graphics” (no quotes)

Step 3 – Once on the Graphics “folder” right click it and choose new DWORD (32-bit) Value

Step 4 – Give the new DWORD a Value name: DisableHardwareAcceleration and give it a Value of 1 – Click OK to save it.

Problem:

You start up and can’t log in or do anything. Many times customers will think thier PC has frozen, but in actuallity it’s just not loading the USB mouse and keyboard drivers on boot (finds new devices but fails the driver install). You can tell this if you see ascreen saver come on or new messages still popping up in the corner.

Solution:

If it’s not finding the driver, quick solution is to point the search to the WindowsInf folder (browse my computer for drivers). This should at least get you functionality.

Setup searches a predefined path on the drive, looking in .inf files to find the best match for the Plug and Play ID of the device. This path is defined in the following registry location and is set to %SystemRoot%Inf by default:

HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionDevicePath: REG_EXPAND_SZ:%SystemRoot%Inf

Adding an entry with the actuall path may solve the problem her. Don’t delete the current path thoguh, add a ; and then type the path
; C:windowsinf

Problem:

How to check optimal WAN MTU settings.

Solution:

The primary reason is that in most if not all cases if you send packets at 1500 they will need to be fragmented resulting in degradation of performance. I would not reccomend changing the MTU settings without first checking the optimal settings for your environment, do not just take the word of your ISP, they are making a generalized statement that covers the masses, it is not a total optomization.

Checking is easy to do. First make sure that your MTU setting is in fact 1500 or the test is compromised and will result in a number that is too low.

The command is to see the largest packet is “ping -f -l XXXX www.XXX.com” -f -l forces the ping packet size to be what you specify, any size to lage returns a reply that the packet needed to be fragmented.

-l is a lowwercase L
XXXX is mtu speeds start at 1500 and decrease in multiples of 10 (1500, 1490, 1480 etc…) until you get a ping result, then increase in multiples of 1 until you again get the reply that the packets needed to be fragmented. The highest numbet that did not have to be fragmented is your highest optimal number. I would actually suggest decreasing it by 2. So if 1464 is the highest you could send without fragmentation set the MTU to 1462.

and XXX is a website of your choosing.

Problem:

The User Profile Service failed the logon, loging on with a temporary account

Solution:

In the past, we’ve “fixed” this by creating a new profile and copying all the data from the old one (in the users or documents and settings folder) over to it. However, you can try this registry fix first;

Step 1. To fix the user profile, click Start and type regedit into the search box and press Enter.

Step 2. Registry Editor will launch and you need to navigate to the following key:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList

Step 3. Click each S-1-5 folder and double-click the ProfileImagePath entry to find out which user account it relates to

Problem:

If security center service is missing or damaged, or antivirus software is not installed and current, Outlook 2010 will not allow sync with other apps without prompt.  Eg. Commit.

Solution:

You could try adding the following key to the registry:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice14.0OutlookSecurity

In this key add the following value:
ObjectModelGuard, DWORD =2

The values 0, 1 and 2 correspond to the options in the Programmatic Access Security settings in the Trust Center.
0 = Warn if Anti-Virus is out of date (recommended)
1 = Always warn
2 = Never warn
