Stop Roku from changing my screen saver Does anybody know a way to stop Roku from changing my screensaver every few weeks when they decide it needs to be different!? I have six Roku devices and I'm continually having to reset my wallpapers because they want their holiday paper on my TV. Trying to STOP the constant changing of my desktop background image Please forgive me for appearing in this forum nude-headed, but I've ripped all my hair out in total frustration. No matter what I do I cannot get Win7 to quit changing my desktop background every few minutes.

First of all, open Run command box (WIN+R), type powercfg.cpl in the box and hit Enter to launch the Power Options window. For your selected power plan, click on Change Plan Settings to modify the settings. Then click on Change advanced power settings to open the Power Options with a lot of power consumption options. Here, look for Desktop Background Settings → Slide show. @ddebus: Have you got a Wallpaper multipack selected, as this would cycle through the wallpapers within the pack in some instances? To address this, head to Settings Wallpaper My Wallpapers, and select an alternative option, or choose one from your Gallery.

If you’re having trouble hanging your wallpaper, or there’s a wall that’s got spots or bubbles in the wallpaper then there are things you can do to fix them.

Poor Colour Or Pattern Match

If you find you are unable to match the pattern on the first 2 or 3 lengths then it may be because too much was trimmed from the edge of the paper during manufacture. Make sure you check the whole batch and take any rejects you find back to your retailer for an exchange.

Colour shade variations can occur in different production batches which is why you should always buy all your rolls at the same time and check they all have the same batch number. If you find rolls with the same batch number still have some variation then you can try and have them replaced by your supplier. If this isn’t possible then use these lengths in areas where they won’t show, such as behind furniture or in window reveals. Look at your room and assess where the light is poorest and use them there so that variations won’t be as obvious.

Persistent Bubbles In Your Wallpaper

Small bubbles should disappear as the wallpaper dries, but sometimes you will have those that persist. These occur because the paper has expanded after hanging, usually the result of not having soaked it long enough or sometimes if you’ve applied new wallpaper over old.

You should always strip any old wallpaper before you hang your new paper as the moisture in the paste can cause the old paper to expand and result in bubbling.

To resolve the problem cut the bubbles with a razor blade and put new paste behind them using an artist’s paint brush. Press the wallpaper back into place and make sure you wipe away any excess paste to avoid staining. If a full length of wallpaper is badly affected by bubbles then you’re better off stripping the whole piece and hanging a new strip, making sure you allow enough time for the to wallpaper soak.

Your Wallpaper Won’t Slide

There are several reasons this can happen: the wall is absorbing the water in the paste, the walls aren’t sized properly or the paste is drying out too quickly.

The wall will absorb water from the paste if it has been mixed with too much water. Always mix according to the instructions on the packet and don’t be tempted to add more water to make it go further. Lay the piece of wallpaper back on your pasting table, make up a fresh batch of thicker paste, and re-apply before attempting to re-hang.

If you think the reason for the lack of slip is that the wall hasn’t been sized properly then make sure you use a glue size on them as this creates better slip than paste.

The last option is that the glue is drying out too quickly – make sure you turn off the heating in the room or try opening a window.

The Relief Pattern Is Flat

This happens when you apply too much pressure to the wallpaper when you are smoothing it onto the wall and occurs most frequently at the seams. Don’t use a seam roller on relief wallpapers. Unfortunately there is nothing you can do to ‘un-flatten’ most relief wallpapers though expanded vinyls will recover with time.

Shiny Patches on Matt Wallpaper

If you have shiny patches on your matt wallpaper then it’s a result of it having been rubbed to hard when being hung, or over time. There’s little you can do to fix shiny patches but taking a ball of white bread and rubbing it over the area can help reduce the problem. Hint: you can also do this to clean non-washable wallpapers.

When hanging matt finish wallpapers try smoothing it with a dry sponge or dry nylon or lambs wool roller.

Staining at the Seams

This happens when old size that was on the wall is reactivated by the water in the new wallpaper paste. Wiping with a clean cloth or rag can help to make them appear less obvious. To prevent this happening in future you should wash down your walls with hot water to remove any old size before preparing your walls for papering.

Gaps at the Seams

If your wallpaper paste wasn’t strong enough to hold the paper it can shrink when it dries – this is why it’s vital you use the correct type of paste for your wallpaper.

You can try painting in the gap with watercolour if you can find a close enough colour match.

Seams Are Lifting

This is a common problem when there hasn’t been enough paste applied to the edges of the wallpaper, and often happens with relief papers and vinyls. Lift the edge of the paper with a knife blade and use an artist’s paintbrush to apply more paste. If you have a vinyl with overlapping edges you can get specialist vinyl seam adhesive.

Before you hang more lengths make sure you apply your paste in sufficient quantities right to the edge of the paper.

Creases in the Paper

This can happen when wallpaper has been hung on an uneven wall, but is more likely the result of being careless when hanging your wallpaper. They can be fixed in the same way as bubbles: tear down the crease (or cut it if it’s a vinyl paper), apply more paste if needed and smooth back down.

To avoid creases in future make sure you fill any cracks or indentations in the wall with filler, or re-skim before wallpapering.

Brown Spots Showing Through The Wallpaper

This can be caused by impurities in the plaster which are the result of using wire wool or a wire brush to prepare the walls. It can also be caused by fungus growth on the wall because of damp and/or cold conditions.

If the problem is severe you will have to strip the wallpaper and redecorate. When preparing the walls make sure you use abrasive paper instead of wire wool or a wire brush. Treat the wall with fungicide if damp is a problem and if you think cold is an issue you can line the wall with expanded polystyrene. If the area is likely to suffer from condensation use a wallpaper paste with fungicide.

Damp Patches on Wallpaper

If, once the wallpaper has dried, you are still left with damp patches then there is either damp striking through the wall or condensation forming on a cold area.

If you ignore the problem it will end up staining your wallpaper so you’ll need to find the source of the damp and treat it. If you do this in a timely manner the damp on the wallpaper should then disappear without leaving any long term effects.

The Paper is Coming Away From The Wall

There are 4 possible causes of this:

1. 1. The paste wasn’t strong enough for the type of wallpaper
2. 2. The wall wasn’t sized
3. 3. The wallpaper has been hung on old distemper or gloss paint
4. 4. Condensation is forming after the wall was prepared

If the problem is only affecting small areas of wallpaper then you can lift the area, apply new paste and press it back into place. If a whole length is affected it will have to be completely removed and replaced.

To prevent this happening in the future make sure you use the correct type of wallpaper paste mixed according to the instructions, prepare the walls thoroughly and eliminate any possible causes of condensation in your room.

How To Repair Damaged Wallpaper

Background For My Laptop

If your wallpaper has torn you can patch it using a piece of leftover wallpaper:

• Tear away the damaged wallpaper leaving only that which is firmly attached to the wall.
• Hold the new wallpaper over the damaged area and adjust it so that the pattern matches.
• Tear a piece from the new paper (don’t cut it) large enough to cover the damage and then tear away about 3mm all around the edge from the back of the paper.
• Paste the patch and lay it over the hole making sure the pattern matches.
• Smooth it down, working from the centre of the patch towards the edges.

Patching Vinyl Wallcovering

You can’t tear vinyl wallpaper like you can standard wallpaper so the repairing technique is different.

• Cut a square of your replacement vinyl paper that’s bigger than the area you’re patching – again, if necessary make sure the pattern matches.
• Tape the square over the hole and using a metal edge and sharp blade cut a square shape through both layers of paper.
• Remove the damaged patch within the square and replace it with the new piece using vinyl paste

If you have a corporate wallpaper pushed to your desktop / laptop, chances are it’s being done with Windows Group Policy. It’s likely this is a PR rather than IT initiative, IT being there to service rather than brand the customer.

You can override this wallpaper with some local settings, although this *may* have impacts down the track where other settings are also blocked. This may or may not be a bad thing, depending on your perspective. It will definitely mean that IT won’t be happy as your PC is no longer standard and may not behave as they expect. This isn’t really a big stress, as with the advent of the Internet and web applications, no machine is the same as another anymore, despite opinions to the contrary. Your mileage may vary.

Prevent Changing Desktop Background Policy

You need to have local administrative rights to make these changes. You may be this already, many laptop users are due to deficiencies in XP. Vista users are less likely to be local admin, as the newer design doesn’t require admin rights as frequently. To test if you are a local admin, try the below steps, if it denies you access, you need to escalate your privileges. Your friendly IT staff member may do this by adding your user account the the local pc administrators group, or alternately you can look at escalation of privilege attacks on the system. It is preferable not to be an administrator all the time, as the computer is MUCH more vulnerable to being attacked if you log on with Administrative access.

There is another way to gain administrative access. Every computer has a default Administrator account. Normally it’s named “Administrator”, but many companies to rename it. If you can get he password for this account, you can logon with it, and do what you want.
If you can’t get the password a nice utility from Peter Nordahl called NT Password Reset Disk will reset the password for the Administrator account, renamed or not. There is some risk with using this tool, but it still worked on NT/2K/XP/Vista including SP1 when I use it. You break your PC, you get to explain to IT what happened.

Once you have admin access you need to open a Registry Editor

Presto – you now own your wallpaper again. You still can’t set it from the usual “Right Click” – select, but changing the path above isn’t too difficult.

The other options you have as workarounds against wallpaper policies depend on where the wallpaper file comes from.

If the file is stored locally on your PC, you can simply replace the file with something else with the same name, and change the permissions to stop it being over-written.

If it’s on the network, if you boot up disconnected, you won’t get the wallpaper.

Happy playing.
