• A while ago I started having trouble with my optical drives. Both of them keep showing up in Explorer as CD/DVD drives on boot, but as soon as I put a disc in either one, it suddenly turns into a hard-drive—“local disk” is displayed in the Type column, though the File System column remains UDF/CDFS. (I though that maybe it was a permission issue on the registry key in HKLM\System\CurrentControlSet..., but I’m not so certain because of the next test.)
• When I try to open a disc (of any type), I get an access denied error message. If I open an elevated command-prompt, I am able to access the files.

Solution

Access to CD/DVD Drive is Denied through Windows 7 Explorer (Permission Problem) from superuser.com

window 7 explorer / My Computer crashes when you open it. somtimes it can be straight away and other times seems random, but you never get long to browse.

---

error was caused by:

c:\windows\system32\thumbcache.dll

this was discovered by reading the event log

---

solution:

empty thumbnail cache with disc cleanup.

spyware could also be the cause of this so service PC if the first option does not work

cursor and keyboard really slow to respond like the laptop is overheating (after this is ruled out) and the computer is running generally slow but laptop responds fine with bartpe or safe mode and when the battery is removed everything runs fine

---

solutions:

1. remove the battery and keep it out
2. buy a new battery
3. disable in device manager, 'Microsoft ACPI-Compliant Method Battery'

when trying to install a extension in joomla you get a Bas Request 400 error. Try the following:

1. delete all cookies and restart browser,
2. Use a different browser
3. possibly empty cache

These version of windows and above are capable of doing an offiline SFC scan via the command line and is very useful if you cannot boot windows.

The following code is what you would use:

• sfc /offwindir= C:\windows /offbootdir= c:\ /scannow

These cheap CCTV systems will only work on internet explorer, in compatability mode, an utilise activeX technology so can be problematic to get working.

---

Solution 1

add website/IP to trusted sites in internet explorer

eg: make sure the ip of the local device 192.168.2.234 is added in to the 'Local intranet' zone as a safe site.

---

Solution 2

This is more indepth just incase solution 1 does not work. In security section make sure all prompts are set properely and this should allow activeX to run normally.

• use internet explorer
• goto to internet options/Security Settings
• select he appropriate zone ie  Internet/Local intranet Zone
• set the following in the
• click on custom level
• goto the 'ActiveX controls and plug-ins' section
• set the following

allow activex filtering enabled ?
allow previous unused activex controls without prompt ?
automatic prompting for activex controls - enabled
download signed activex controls ? - prompt
download unsigned activex controls - prompt
intitialize and script activexcontrols not marked as safe for scripting - prompt
run activex controls and plug-ins - enabled ?

 

if any issues reuce all security, try and load, tehn reset all ie settings to default
